compatible with C99 and C++. + + +Initialization +-------------- + +In order to use the API, OSPRay must be initialized with a "device". A +device is the object which implements the API. Creating and initializing +a device can be done in either of two ways: command line arguments or +manually instantiating a device. + +### Command Line Arguments + +The first is to do so by giving OSPRay the command line from `main()` by +calling + + OSPError ospInit(int *argc, const char **argv); + +OSPRay parses (and removes) its known command line parameters from your +application's `main` function. For an example see the [tutorial]. For +possible error codes see section [Error Handling and Status Messages]. +It is important to note that the arguments passed to `ospInit()` are +processed in order they are listed. The following parameters (which are +prefixed by convention with "`--osp:`") are understood: + + -------------------------- ----------------------------------------------------- + Parameter Description + -------------------------- ----------------------------------------------------- + `--osp:debug` enables various extra checks and debug output, and + disables multi-threading + + `--osp:numthreads ` use `n` threads instead of per default using all + detected hardware threads + + `--osp:loglevel ` set logging level, default `0`; increasing `n` means + increasingly verbose log messages + + `--osp:verbose` shortcut for `--osp:loglevel 1` + + `--osp:vv` shortcut for `--osp:loglevel 2` + + `--osp:module:` load a module during initialization; equivalent to + calling `ospLoadModule(name)` + + `--osp:mpi` enables MPI mode for parallel rendering with the + `mpi_offload` device, to be used in conjunction with + `mpirun`; this will automatically load the "mpi" + module if it is not yet loaded or linked + + `--osp:mpi-offload` same as `--osp:mpi` + + `--osp:mpi-distributed` same as `--osp:mpi`, but will create an + `mpi_distributed` device instead; Note that this + will likely require application changes to work + properly + + `--osp:logoutput ` convenience for setting where status messages go; + valid values for `dst` are `cerr` and `cout` + + `--osp:erroroutput ` convenience for setting where error messages go; + valid values for `dst` are `cerr` and `cout` + + `--osp:device:` use `name` as the type of device for OSPRay to + create; e.g. `--osp:device:default` gives you the + default local device; Note if the device to be used + is defined in a module, remember to pass + `--osp:module:` first + + `--osp:setaffinity ` if `1`, bind software threads to hardware threads; + `0` disables binding; default is `1` on KNL and `0` + otherwise + -------------------------- ----------------------------------------------------- + : Command line parameters accepted by OSPRay's `ospInit`. + +### Manual Device Instantiation + +The second method of initialization is to explicitly create the device +yourself, and possibly set parameters. This method looks almost +identical to how other [objects] are created and used by OSPRay +(described in later sections). The first step is to create the device +with + + OSPDevice ospNewDevice(const char *type); + +where the `type` string maps to a specific device implementation. OSPRay +always provides the "`default`" device, which maps to a local CPU +rendering device. If it is enabled in the build, you can also use +"`mpi`" to access the MPI multi-node rendering device (see [Parallel +Rendering with MPI] section for more information). Once a device is +created, you can call + + void ospDeviceSet1i(OSPDevice, const char *id, int val); + void ospDeviceSetString(OSPDevice, const char *id, const char *val); + void ospDeviceSetVoidPtr(OSPDevice, const char *id, void *val); + +to set parameters on the device. The following parameters can be set on +all devices: + + ------ ------------ ---------------------------------------------------------- + Type Name Description + ------ ------------ ---------------------------------------------------------- + int numThreads number of threads which OSPRay should use + + int logLevel logging level + + string logOutput convenience for setting where status messages go; valid + values are `cerr` and `cout` + + string errorOutput convenience for setting where error messages go; valid + values are `cerr` and `cout` + + int debug set debug mode; equivalent to logLevel=2 and numThreads=1 + + int setAffinity bind software threads to hardware threads if set to 1; + 0 disables binding omitting the parameter will let OSPRay + choose + ------ ------------ ---------------------------------------------------------- + : Parameters shared by all devices. + +Once parameters are set on the created device, the device must be +committed with + + void ospDeviceCommit(OSPDevice); + +To use the newly committed device, you must call + + void ospSetCurrentDevice(OSPDevice); + +This then sets the given device as the object which will respond to all +other OSPRay API calls. + +Users can change parameters on the device after initialization (from +either method above), by calling + + OSPDevice ospGetCurrentDevice(); + +This function returns the handle to the device currently used to respond +to OSPRay API calls, where users can set/change parameters and recommit +the device. If changes are made to the device that is already set as the +current device, it does not need to be set as current again. + +### Environment Variables + +Finally, OSPRay's generic device parameters can be overridden via +environment variables for easy changes to OSPRay's behavior without +needing to change the application (variables are prefixed by convention +with "`OSPRAY_`"): + + Variable Description + ------------------- --------------------------------- + OSPRAY_THREADS equivalent to `--osp:numthreads` + OSPRAY_LOG_LEVEL equivalent to `--osp:loglevel` + OSPRAY_LOG_OUTPUT equivalent to `--osp:logoutput` + OSPRAY_ERROR_OUTPUT equivalent to `--osp:erroroutput` + OSPRAY_DEBUG equivalent to `--osp:debug` + OSPRAY_SET_AFFINITY equivalent to `--osp:setaffinity` + ------------------- --------------------------------- + : Environment variables interpreted by OSPRay. + +### Error Handling and Status Messages + +The following errors are currently used by OSPRay: + + Name Description + ---------------------- ------------------------------------------------------- + OSP_NO_ERROR no error occurred + OSP_UNKNOWN_ERROR an unknown error occurred + OSP_INVALID_ARGUMENT an invalid argument was specified + OSP_INVALID_OPERATION the operation is not allowed for the specified object + OSP_OUT_OF_MEMORY there is not enough memory to execute the command + OSP_UNSUPPORTED_CPU the CPU is not supported (minimum ISA is SSE4.1) + ---------------------- ------------------------------------------------------- + : Possible error codes, i.e. valid named constants of type `OSPError`. + +These error codes are either directly return by some API functions, or +are recorded to be later queried by the application via + + OSPError ospDeviceGetLastErrorCode(OSPDevice); + +A more descriptive error message can be queried by calling + + const char* ospDeviceGetLastErrorMsg(OSPDevice); + +Alternatively, the application can also register a callback function of +type + + typedef void (*OSPErrorFunc)(OSPError, const char* errorDetails); + +via + + void ospDeviceSetErrorFunc(OSPDevice, OSPErrorFunc); + +to get notified when errors occur. + +Applications may be interested in messages which OSPRay emits, whether +for debugging or logging events. Applications can call + + void ospDeviceSetStatusFunc(OSPDevice, OSPStatusFunc); + +in order to register a callback function of type + + typedef void (*OSPStatusFunc)(const char* messageText); + +which OSPRay will use to emit status messages. By default, OSPRay uses a +callback which does nothing, so any output desired by an application +will require that a callback is provided. Note that callbacks for C++ +`std::cout` and `std::cerr` can be alternatively set through `ospInit()` +or the `OSPRAY_LOG_OUTPUT` environment variable. + +### Loading OSPRay Extensions at Runtime + +OSPRay's functionality can be extended via plugins, which are +implemented in shared libraries. To load plugin `name` from +`libospray_module_.so` (on Linux and Mac OS\ X) or +`ospray_module_.dll` (on Windows) use + + OSPError ospLoadModule(const char *name); + +Modules are searched in OS-dependent paths. `ospLoadModule` returns +`OSP_NO_ERROR` if the plugin could be successfully loaded. + + +Objects +------- + +All entities of OSPRay (the renderer, volumes, geometries, lights, +cameras, ...) are a specialization of `OSPObject` and share common +mechanism to deal with parameters and lifetime. + +An important aspect of object parameters is that parameters do not get +passed to objects immediately. Instead, parameters are not visible at +all to objects until they get explicitly committed to a given object via +a call to + + void ospCommit(OSPObject); + +at which time all previously additions or changes to parameters are +visible at the same time. If a user wants to change the state of an +existing object (e.g., to change the origin of an already existing +camera) it is perfectly valid to do so, as long as the changed +parameters are recommitted. + +The commit semantic allow for batching up multiple small changes, and +specifies exactly when changes to objects will occur. This is important +to ensure performance and consistency for devices crossing a PCI bus, or +across a network. In our MPI implementation, for example, we can easily +guarantee consistency among different nodes by MPI barrier’ing on every +commit. + +Note that OSPRay uses reference counting to manage the lifetime of all +objects, so one cannot explicitly "delete" any object. Instead, to +indicate that the application does not need and does not access the +given object anymore, call + + void ospRelease(OSPObject); + +This decreases its reference count and if the count reaches `0` the +object will automatically get deleted. + +### Parameters + +Parameters allow to configure the behavior of and to pass data to +objects. However, objects do _not_ have an explicit interface for +reasons of high flexibility and a more stable compile-time API. Instead, +parameters are passed separately to objects in an arbitrary order, and +unknown parameters will simply be ignored. The following functions allow +adding various types of parameters with name `id` to a given object: + + // add a C-string (zero-terminated char *) parameter + void ospSetString(OSPObject, const char *id, const char *s); + + // add an object handle parameter to another object + void ospSetObject(OSPObject, const char *id, OSPObject object); + + // add an untyped pointer -- this will *ONLY* work in local rendering! + void ospSetVoidPtr(OSPObject, const char *id, void *v); + + // add scalar and vector integer and float parameters + void ospSetf (OSPObject, const char *id, float x); + void ospSet1f (OSPObject, const char *id, float x); + void ospSet1i (OSPObject, const char *id, int32_t x); + void ospSet2f (OSPObject, const char *id, float x, float y); + void ospSet2fv(OSPObject, const char *id, const float *xy); + void ospSet2i (OSPObject, const char *id, int x, int y); + void ospSet2iv(OSPObject, const char *id, const int *xy); + void ospSet3f (OSPObject, const char *id, float x, float y, float z); + void ospSet3fv(OSPObject, const char *id, const float *xyz); + void ospSet3i (OSPObject, const char *id, int x, int y, int z); + void ospSet3iv(OSPObject, const char *id, const int *xyz); + void ospSet4f (OSPObject, const char *id, float x, float y, float z, float w); + void ospSet4fv(OSPObject, const char *id, const float *xyzw); + + // additional functions to pass vector integer and float parameters in C++ + void ospSetVec2f(OSPObject, const char *id, const vec2f &v); + void ospSetVec2i(OSPObject, const char *id, const vec2i &v); + void ospSetVec3f(OSPObject, const char *id, const vec3f &v); + void ospSetVec3i(OSPObject, const char *id, const vec3i &v); + void ospSetVec4f(OSPObject, const char *id, const vec4f &v); + +Users can also remove parameters that have been explicitly set via an +ospSet call. Any parameters which have been removed will go back to +their default value during the next commit unless a new parameter +was set after the parameter was removed. The following API function +removes the named parameter from the given object: + + void ospRemoveParam(OSPObject, const char *id); + +### Data + +There is also the possibility to aggregate many values of the same type +into an array, which then itself can be used as a parameter to objects. +To create such a new data buffer, holding `numItems` elements of the +given type, from the initialization data pointed to by `source` and +optional creation flags, use + + OSPData ospNewData(size_t numItems, + OSPDataType, + const void *source, + const uint32_t dataCreationFlags = 0); + +The call returns an `OSPData` handle to the created array. The flag +`OSP_DATA_SHARED_BUFFER` indicates that the buffer can be shared with +the application. In this case the calling program guarantees that the +`source` pointer will remain valid for the duration that this data array +is being used. The enum type `OSPDataType` describes the different data +types that can be represented in OSPRay; valid constants are listed in +the table below. + + Type/Name Description + ---------------------- ----------------------------------------------- + OSP_DEVICE API device object reference + OSP_VOID_PTR void pointer + OSP_DATA data reference + OSP_OBJECT generic object reference + OSP_CAMERA camera object reference + OSP_FRAMEBUFFER framebuffer object reference + OSP_LIGHT light object reference + OSP_MATERIAL material object reference + OSP_TEXTURE texture object reference + OSP_RENDERER renderer object reference + OSP_MODEL model object reference + OSP_GEOMETRY geometry object reference + OSP_VOLUME volume object reference + OSP_TRANSFER_FUNCTION transfer function object reference + OSP_PIXEL_OP pixel operation object reference + OSP_STRING C-style zero-terminated character string + OSP_CHAR 8\ bit signed character scalar + OSP_UCHAR 8\ bit unsigned character scalar + OSP_UCHAR[234] ... and [234]-element vector + OSP_USHORT 16\ bit unsigned integer scalar + OSP_INT 32\ bit signed integer scalar + OSP_INT[234] ... and [234]-element vector + OSP_UINT 32\ bit unsigned integer scalar + OSP_UINT[234] ... and [234]-element vector + OSP_LONG 64\ bit signed integer scalar + OSP_LONG[234] ... and [234]-element vector + OSP_ULONG 64\ bit unsigned integer scalar + OSP_ULONG[234] ... and [234]-element vector + OSP_FLOAT 32\ bit single precision floating point scalar + OSP_FLOAT[234] ... and [234]-element vector + OSP_FLOAT3A ... and aligned 3-element vector + OSP_DOUBLE 64\ bit double precision floating point scalar + ---------------------- ----------------------------------------------- + : Valid named constants for `OSPDataType`. + +To add a data array as parameter named `id` to another object call + + void ospSetData(OSPObject, const char *id, OSPData); + + +Volumes +------- + +Volumes are volumetric datasets with discretely sampled values in 3D +space, typically a 3D scalar field. To create a new volume object of +given type `type` use + + OSPVolume ospNewVolume(const char *type); + +The call returns `NULL` if that type of volume is not known by OSPRay, +or else an `OSPVolume` handle. + +The common parameters understood by all volume variants are summarized +in the table below. + + ------ ------------------------ --------- ----------------------------------- + Type Name Default Description + ------ ------------------------ --------- ----------------------------------- + vec2f voxelRange minimum and maximum of the scalar + values + + bool gradientShadingEnabled false volume is rendered with surface + shading wrt. to normalized gradient + + bool preIntegration false use pre-integration for + [transfer function] lookups + + bool singleShade true shade only at the point of maximum + intensity + + bool adaptiveSampling true adapt ray step size based on + opacity + + float adaptiveScalar 15 modifier for adaptive step size + + float adaptiveMaxSamplingRate 2 maximum sampling rate for adaptive + sampling + + float samplingRate 0.125 sampling rate of the volume (this + is the minimum step size for + adaptive sampling) + + vec3f specular gray 0.3 specular color for shading + + vec3f volumeClippingBoxLower disabled lower coordinate (in object-space) + to clip the volume values + + vec3f volumeClippingBoxUpper disabled upper coordinate (in object-space) + to clip the volume values + ------ ------------------------ --------- ----------------------------------- + : Configuration parameters shared by all volume types. + +Note that if `voxelRange` is not provided for a volume then OSPRay will +compute it based on the voxel data, which may result in slower data +updates. + +### Structured Volume + +Structured volumes only need to store the values of the samples, because +their addresses in memory can be easily computed from a 3D position. A +common type of structured volumes are regular grids. OSPRay supports two +variants that differ in how the volumetric data for the regular grids is +specified. + +The first variant shares the voxel data with the application. Such a +volume type is created by passing the type string +"`shared_structured_volume`" to `ospNewVolume`. The voxel data is laid +out in memory in XYZ order and provided to the volume via a [data] +buffer parameter named "`voxelData`". + +The second regular grid variant is optimized for rendering performance: +data locality in memory is increased by arranging the voxel data in +smaller blocks. This volume type is created by passing the type string +"`block_bricked_volume`" to `ospNewVolume`. Because of this +rearrangement of voxel data it cannot be shared the with the application +anymore, but has to be transferred to OSPRay via + + OSPError ospSetRegion(OSPVolume, void *source, + const vec3i ®ionCoords, + const vec3i ®ionSize); + +The voxel data pointed to by `source` is copied into the given volume +starting at position `regionCoords`, must be of size `regionSize` and be +placed in memory in XYZ order. Note that OSPRay distinguishes between +volume data and volume parameters. This function must be called only +after all volume parameters (in particular `dimensions` and `voxelType`, +see below) have been set and _before_ `ospCommit(volume)` is called. +If necessary then memory for the volume is allocated on the first call +to this function. + +The common parameters understood by both structured volume variants are +summarized in the table below. + + ------ ----------- ----------- ----------------------------------- + Type Name Default Description + ------ ----------- ----------- ----------------------------------- + vec3i dimensions number of voxels in each + dimension $(x, y, z)$ + + string voxelType data type of each voxel, + currently supported are: + + "uchar" (8\ bit unsigned integer) + + "short" (16\ bit signed integer) + + "ushort" (16\ bit unsigned integer) + + "float" (32\ bit single precision + floating point) + + "double" (64\ bit double precision + floating point) + + vec3f gridOrigin $(0, 0, 0)$ origin of the grid in world-space + + vec3f gridSpacing $(1, 1, 1)$ size of the grid cells in + world-space + ------ ----------- ----------- ----------------------------------- + : Additional configuration parameters for structured volumes. + +### Adaptive Mesh Refinement (AMR) Volume + +AMR volumes are specified as a list of bricks, which are levels of +refinement in potentially overlapping regions. There can be any number +of refinement levels and any number of bricks at any level of +refinement. An AMR volume type is created by passing the type string +"`amr_volume`" to `ospNewVolume`. + +Applications should first create an `OSPData` array which holds +information about each brick. The following structure is used to +populate this array (found in `ospray.h`): + + struct amr_brick_info + { + box3i bounds; + int refinementLevel; + float cellWidth; + }; + +Then for each brick, the application should create an `OSPData` array of +`OSPData` handles, where each handle is the data per-brick. Currently we +only support `float` voxels. + + ------- ----------- ----------- ----------------------------------- + Type Name Default Description + ------- ----------- ----------- ----------------------------------- + vec3f gridOrigin $(0, 0, 0)$ origin of the grid in world-space + + vec3f gridSpacing $(1, 1, 1)$ size of the grid cells in + world-space + + string amrMethod current sampling method; valid values are + "finest", "current", or "octant" + + string voxelType undefined data type of each voxel, + currently supported are: + + "uchar" (8\ bit unsigned integer) + + "short" (16\ bit signed integer) + + "ushort" (16\ bit unsigned integer) + + "float" (32\ bit single precision + floating point) + + "double" (64\ bit double precision + floating point) + + OSPData brickInfo array of info defining each brick + + OSPData brickData array of handles to per-brick + voxel data + ------- ----------- ----------- ----------------------------------- + : Additional configuration parameters for AMR volumes. + +Lastly, note that the `gridOrigin` and `gridSpacing` parameters act just +like the structured volume equivalent, but they only modify the root +(coarsest level) of refinement. + +### Unstructured Volumes + +Unstructured volumes can contain tetrahedral or hexahedral cell types, +and are defined by three arrays: vertices, corresponding field values, +and eight indices per cell (first four are -1 for tetrahedral +cells). An unstructred volume type is created by passing the type +string "`unstructured_volume`" to `ospNewVolume`. + +Similar to [triangle mesh], each tetrahedron is formed by a group of +indices into the vertices. For each vertex, the corresponding (by array +index) data value will be used for sampling when rendering. Note that +the index order for each tetrahedron does not matter, as OSPRay +internally calculates vertex normals to ensure proper sampling and +interpolation. + +For hexahedral cells, each hexahedron is formed by a group of eight +indices into the vertics and data value. Vertex ordering is the same +as VTK_HEXAHEDRON - four bottom vertices counterclockwise, then top +four counterclockwise. + + Type Name Description + -------- ----------- ------------------------------------------------------------ + vec3f[] vertices [data] array of vertex positions + float[] field [data] array of vertex data values to be sampled + vec4i[] intices [data] array of tetrahedra indices (into vertices and field) + string hexMethod 'planar' (default) or 'nonplanar' + -------- ----------- ------------------------------------------------------------ + : Additional configuration parameters for tetrahedral volumes. + +### Transfer Function + +Transfer functions map the scalar values of volumes to color and opacity +and thus they can be used to visually emphasize certain features of the +volume. To create a new transfer function of given type `type` use + + OSPTransferFunction ospNewTransferFunction(const char *type); + +The call returns `NULL` if that type of transfer functions is not known +by OSPRay, or else an `OSPTransferFunction` handle to the created +transfer function. That handle can be assigned to a volume as parameter +"`transferFunction`" using `ospSetObject`. + +One type of transfer function that is built-in in OSPRay is the linear +transfer function, which interpolates between given equidistant colors +and opacities. It is create by passing the string "`piecewise_linear`" +to `ospNewTransferFunction` and it is controlled by these parameters: + + Type Name Description + ------------ ----------- ---------------------------------------------- + vec3f[] colors [data] array of RGB colors + float[] opacities [data] array of opacities + vec2f valueRange domain (scalar range) this function maps from + ------------ ----------- ---------------------------------------------- + : Parameters accepted by the linear transfer function. + + +Geometries +---------- + +Geometries in OSPRay are objects that describe surfaces. To create a +new geometry object of given type `type` use + + OSPGeometry ospNewGeometry(const char *type); + +The call returns `NULL` if that type of geometry is not known by OSPRay, +or else an `OSPGeometry` handle. + +### Triangle Mesh + +A traditional triangle mesh (indexed face set) geometry is created by +calling `ospNewGeometry` with type string "`triangles`". Once created, a +triangle mesh recognizes the following parameters: + + Type Name Description + ------------------ ---------------- ------------------------------------------------- + vec3f(a)[] vertex [data] array of vertex positions + vec3f(a)[] vertex.normal [data] array of vertex normals + vec4f[] / vec3fa[] vertex.color [data] array of vertex colors (RGBA/RGB) + vec2f[] vertex.texcoord [data] array of vertex texture coordinates + vec3i(a)[] index [data] array of triangle indices (into vertex.*) + ------------------ ---------------- ------------------------------------------------- + : Parameters defining a triangle mesh geometry. + +### Spheres + +A geometry consisting of individual spheres, each of which can have an +own radius, is created by calling `ospNewGeometry` with type string +"`spheres`". The spheres will not be tessellated but rendered +procedurally and are thus perfectly round. To allow a variety of sphere +representations in the application this geometry allows a flexible way +of specifying the data of center position and radius within a [data] +array: + + ---------- ----------------- -------- --------------------------------------- + Type Name Default Description + ---------- ----------------- -------- --------------------------------------- + float radius 0.01 radius of all spheres + (if `offset_radius` is not used) + + OSPData spheres NULL memory holding the spatial [data] of + all spheres + + int bytes_per_sphere 16 size (in bytes) of each sphere within + the `spheres` array + + int offset_center 0 offset (in bytes) of each sphere's + "vec3f center" position (in + object-space) within the `spheres` + array + + int offset_radius -1 offset (in bytes) of each sphere's + "float radius" within the `spheres` + array (`-1` means disabled and use + `radius`) + + vec4f[] / color NULL [data] array of colors (RGBA/RGB), + vec3f(a)[] color is constant for each sphere + + vec2f[] texcoord NULL [data] array of texture coordinates, + coordinate is constant for each sphere + ---------- ----------------- -------- --------------------------------------- + : Parameters defining a spheres geometry. + +### Cylinders + +A geometry consisting of individual cylinders, each of which can have an +own radius, is created by calling `ospNewGeometry` with type string +"`cylinders`". The cylinders will not be tessellated but rendered +procedurally and are thus perfectly round. To allow a variety of cylinder +representations in the application this geometry allows a flexible way +of specifying the data of offsets for start position, end position and +radius within a [data] array. All parameters are listed in the table +below. + + ---------- ------------------- -------- ------------------------------------- + Type Name Default Description + ---------- ------------------- -------- ------------------------------------- + float radius 0.01 radius of all cylinders + (if `offset_radius` is not used) + + OSPData cylinders NULL memory holding the spatial [data] of + all cylinders + + int bytes_per_cylinder 24 size (in bytes) of each cylinder + within the `cylinders` array + + int offset_v0 0 offset (in bytes) of each cylinder's + "vec3f v0" position (the start + vertex, in object-space) within the + `cylinders` array + + int offset_v1 12 offset (in bytes) of each cylinder's + "vec3f v1" position (the end vertex, + in object-space) within the + `cylinders` array + + int offset_radius -1 offset (in bytes) of each cylinder's + "float radius" within the `cylinders` + array (`-1` means disabled and use + `radius` instead) + + vec4f[] / color NULL [data] array of colors (RGBA/RGB), + vec3f(a)[] color is constant for each cylinder + + OSPData texcoord NULL [data] array of texture coordinates, + in pairs (each a vec2f at vertex v0 + and v1) + ---------- ------------------- -------- ------------------------------------- + : Parameters defining a cylinders geometry. + +For texturing each cylinder is seen as a 1D primitive, i.e. a line +segment: the 2D texture coordinates at its vertices v0 and v1 are +linearly interpolated. + +### Streamlines + +A geometry consisting of multiple streamlines is created by calling +`ospNewGeometry` with type string "`streamlines`". The streamlines are +internally assembled either from connected (and rounded) cylinder +segments, or represented as Bézier curves; they are thus always +perfectly round. The parameters defining this geometry are listed in the +table below. + + ------------------ ------------- -------------------------------------------- + Type Name Description + ------------------ ------------- -------------------------------------------- + float radius global radius of all streamlines (if + per-vertex radius is not used), default 0.01 + + bool smooth enable curve interpolation, default off + (always on if per-vertex radius is used) + + vec3fa[] / vec4f[] vertex [data] array of all vertex position (and + optional radius) for *all* streamlines + + vec4f[] vertex.color [data] array of corresponding vertex + colors (RGBA) + + float[] vertex.radius [data] array of corresponding vertex radius + + int32[] index [data] array of indices to the first vertex + of a link + ------------------ ------------- -------------------------------------------- + : Parameters defining a streamlines geometry. + +Each streamline is specified by a set of (aligned) control points in +`vertex`. If `smooth` is disabled and a constant `radius` is used for +all streamlines then all vertices belonging to to the same logical +streamline are connected via [cylinders], with additional [spheres] at +each vertex to create a continuous, closed surface. Otherwise, +streamlines are represented as Bézier curves, smoothly interpolating the +vertices. This mode supports per-vertex varying radii (either given in +`vertex.radius`, or in the 4th component of a *vec4f* `vertex`), but is +slower and consumes more memory. Also, the radius needs to be smaller +than the curvature radius of the Bézier curve at each location on the +curve. + +A streamlines geometry can contain multiple disjoint streamlines, each +streamline is specified as a list of linear segments (or links) +referenced via `index`: each entry `e` of the `index` array points the +first vertex of a link (`vertex[index[e]]`) and the second vertex of the +link is implicitly the directly following one (`vertex[index[e]+1]`). +For example, two streamlines of vertices `(A-B-C-D)` and `(E-F-G)`, +respectively, would internally correspond to five links (`A-B`, `B-C`, +`C-D`, `E-F`, and `F-G`), and would be specified via an array of +vertices `[A,B,C,D,E,F,G]`, plus an array of link indices `[0,1,2,4,5]`. + +### Isosurfaces + +OSPRay can directly render multiple isosurfaces of a volume without +first tessellating them. To do so create an isosurfaces geometry by +calling `ospNewGeometry` with type string "`isosurfaces`". Each +isosurface will be colored according to the provided volume's [transfer +function]. + + Type Name Description + ---------- ---------- ------------------------------------------------------ + float[] isovalues [data] array of isovalues + OSPVolume volume handle of the [volume] to be isosurfaced + ---------- ---------- ------------------------------------------------------ + : Parameters defining an isosurfaces geometry. + +### Slices + +One tool to highlight interesting features of volumetric data is to +visualize 2D cuts (or slices) by placing planes into the volume. Such a +slices geometry is created by calling `ospNewGeometry` with type string +"`slices`". The planes are defined by the coefficients $(a,b,c,d)$ of +the plane equation $ax + by + cz + d = 0$. Each slice is colored +according to the provided volume's [transfer function]. + + + Type Name Description + ---------- ---------- ---------------------------------------------------- + vec4f[] planes [data] array with plane coefficients for all slices + OSPVolume volume handle of the [volume] that will be sliced + ---------- ---------- ---------------------------------------------------- + : Parameters defining a slices geometry. + +### Instances + +OSPRay supports instancing via a special type of geometry. Instances are +created by transforming another given [model] `modelToInstantiate` with +the given affine transformation `transform` by calling + + OSPGeometry ospNewInstance(OSPModel modelToInstantiate, const affine3f &transform); + + +Renderer +-------- + +A renderer is the central object for rendering in OSPRay. Different +renderers implement different features and support different materials. +To create a new renderer of given type `type` use + + OSPRenderer ospNewRenderer(const char *type); + +The call returns `NULL` if that type of renderer is not known, or else +an `OSPRenderer` handle to the created renderer. General parameters of +all renderers are + + ----------- ------------------ -------- ---------------------------------------- + Type Name Default Description + ----------- ------------------ -------- ---------------------------------------- + OSPModel model the [model] to render + + OSPCamera camera the [camera] to be used for rendering + + OSPLight[] lights [data] array with handles of the [lights] + + float epsilon 10^-6^ ray epsilon to avoid self-intersections, + relative to scene diameter + + int spp 1 samples per pixel + + int maxDepth 20 maximum ray recursion depth + + float minContribution 0.001 sample contributions below this value + will be neglected to speed-up rendering + + float varianceThreshold 0 threshold for adaptive accumulation + ----------- ------------------ -------- ---------------------------------------- + : Parameters understood by all renderers. + +OSPRay's renderers support a feature called adaptive accumulation, which +accelerates progressive [rendering] by stopping the rendering and +refinement of image regions that have an estimated variance below the +`varianceThreshold`. This feature requires a [framebuffer] with an +`OSP_FB_VARIANCE` channel. + +### SciVis Renderer + +The SciVis renderer is a fast ray tracer for scientific visualization +which supports volume rendering and ambient occlusion (AO). It is +created by passing the type string "`scivis`" or "`raytracer`" to +`ospNewRenderer`. In addition to the [general parameters](#renderer) +understood by all renderers the SciVis renderer supports the following +special parameters: + + ------------- ---------------------- ------------ ---------------------------- + Type Name Default Description + ------------- ---------------------- ------------ ---------------------------- + bool shadowsEnabled false whether to compute (hard) + shadows + + int aoSamples 0 number of rays per sample to + compute ambient occlusion + + float aoDistance 10^20^ maximum distance to consider + for ambient occlusion + + bool aoTransparencyEnabled false whether object transparency + is respected when computing + ambient occlusion (slower) + + bool oneSidedLighting true if true back-facing + surfaces (wrt. light source) + receive no illumination + + float / bgColor black, background color and alpha + vec3f / vec4f transparent (RGBA) + + OSPTexture2D maxDepthTexture NULL screen-sized float [texture] + with maximum far distance + per pixel + ------------- ---------------------- ------------ ---------------------------- + : Special parameters understood by the SciVis renderer. + +Note that the intensity (and color) of AO is controlled via an [ambient +light]. If `aoSamples` is zero (the default) then ambient lights cause +ambient illumination (without occlusion). + +Per default the background of the rendered image will be transparent +black, i.e. the alpha channel holds the opacity of the rendered objects. +This facilitates transparency-aware blending of the image with an +arbitrary background image by the application. The parameter `bgColor` +can be used to already blend with a constant background color (and +alpha) during rendering. + +The SciVis renderer supports depth composition with images of other +renderers, for example to incorporate help geometries of a 3D UI that +were rendered with OpenGL. The screen-sized [texture] `maxDepthTexture` +must have format `OSP_TEXTURE_R32F` and flag +`OSP_TEXTURE_FILTER_NEAREST`. The fetched values are used to limit the +distance of primary rays, thus objects of other renderers can hide +objects rendered by OSPRay. + +### Path Tracer + +The path tracer supports soft shadows, indirect illumination and +realistic materials. This renderer is created by passing the type string +"`pathtracer`" to `ospNewRenderer`. In addition to the [general +parameters](#renderer) understood by all renderers the path tracer +supports the following special parameters: + + ------------- ---------------- -------- ------------------------------------- + Type Name Default Description + ------------- ---------------- -------- ------------------------------------- + int rouletteDepth 5 ray recursion depth at which to + start Russian roulette termination + + float maxContribution ∞ samples are clamped to this value + before they are accumulated into + the framebuffer + + OSPTexture2D backplate NULL [texture] image used as background, + replacing visible lights in infinity + (e.g. the [HDRI light]) + ------------- ---------------- -------- ------------------------------------- + : Special parameters understood by the path tracer. + +The path tracer requires that [materials] are assigned to [geometries], +otherwise surfaces are treated as completely black. + +### Model + +Models are a container of scene data. They can hold the different +[geometries] and [volumes] as well as references to (and [instances] of) +other models. A model is associated with a single logical acceleration +structure. To create an (empty) model call + + OSPModel ospNewModel(); + +The call returns an `OSPModel` handle to the created model. To add an +already created geometry or volume to a model use + + void ospAddGeometry(OSPModel, OSPGeometry); + void ospAddVolume(OSPModel, OSPVolume); + +An existing geometry or volume can be removed from a model with + + void ospRemoveGeometry(OSPModel, OSPGeometry); + void ospRemoveVolume(OSPModel, OSPVolume); + +### Lights + +To let the given `renderer` create a new light source of given type +`type` use + + OSPLight ospNewLight(OSPRenderer renderer, const char *type); + +The call returns `NULL` if that type of light is not known by the +renderer, or else an `OSPLight` handle to the created light source. +All light sources[^1] accept the following parameters: + + Type Name Default Description + --------- ---------- -------- --------------------------------------- + vec3f(a) color white color of the light + float intensity 1 intensity of the light (a factor) + bool isVisible true whether the light can be directly seen + --------- ---------- -------- --------------------------------------- + : Parameters accepted by the all lights. + +The following light types are supported by most OSPRay renderers. + +[^1]: The [HDRI Light] is an exception, it knows about `intensity`, but +not about `color`. + +#### Directional Light / Distant Light + +The distant light (or traditionally the directional light) is thought to +be very far away (outside of the scene), thus its light arrives (almost) +as parallel rays. It is created by passing the type string "`distant`" +to `ospNewLight`. In addition to the [general parameters](#lights) +understood by all lights the distant light supports the following special +parameters: + + Type Name Description + --------- ---------------- --------------------------------------------- + vec3f(a) direction main emission direction of the distant light + float angularDiameter apparent size (angle in degree) of the light + --------- ---------------- --------------------------------------------- + : Special parameters accepted by the distant light. + +Setting the angular diameter to a value greater than zero will result in +soft shadows when the renderer uses stochastic sampling (like the [path +tracer]). For instance, the apparent size of the sun is about 0.53°. + +#### Point Light / Sphere Light + +The sphere light (or the special case point light) is a light emitting +uniformly in all directions. It is created by passing the type string +"`sphere`" to `ospNewLight`. In addition to the [general +parameters](#lights) understood by all lights the sphere light supports +the following special parameters: + + Type Name Description + --------- --------- ----------------------------------------------- + vec3f(a) position the center of the sphere light, in world-space + float radius the size of the sphere light + --------- --------- ----------------------------------------------- + : Special parameters accepted by the sphere light. + +Setting the radius to a value greater than zero will result in soft +shadows when the renderer uses stochastic sampling (like the [path +tracer]). + +#### Spot Light + +The spot light is a light emitting into a cone of directions. It is +created by passing the type string "`spot`" to `ospNewLight`. In +addition to the [general parameters](#lights) understood by all lights +the spot light supports the special parameters listed in the table. + + -------- ------------- ---------------------------------------------- + Type Name Description + -------- ------------- ---------------------------------------------- + vec3f(a) position the center of the spot light, in world-space + + vec3f(a) direction main emission direction of the spot + + float openingAngle full opening angle (in degree) of the spot; + outside of this cone is no illumination + + float penumbraAngle size (angle in degree) of the "penumbra", the + region between the rim (of the illumination + cone) and full intensity of the spot; should + be smaller than half of `openingAngle` + + float radius the size of the spot light, the radius of a + disk with normal `direction` + -------- ------------- ---------------------------------------------- + : Special parameters accepted by the spot light. + +![Angles used by SpotLight.][imgSpotLight] + +Setting the radius to a value greater than zero will result in soft +shadows when the renderer uses stochastic sampling (like the [path +tracer]). + +#### Quad Light + +The quad^[actually a parallelogram] light is a planar, procedural area light source emitting +uniformly on one side into the half space. It is created by passing the +type string "`quad`" to `ospNewLight`. In addition to the [general +parameters](#lights) understood by all lights the spot light supports +the following special parameters: + + Type Name Description + --------- --------- ----------------------------------------------------- + vec3f(a) position world-space position of one vertex of the quad light + vec3f(a) edge1 vector to one adjacent vertex + vec3f(a) edge2 vector to the other adjacent vertex + --------- --------- ----------------------------------------------------- + : Special parameters accepted by the quad light. + +![Defining a Quad Light.][imgQuadLight] + +The emission side is determined by the cross product of `edge1`×`edge2`. +Note that only renderers that use stochastic sampling (like the path +tracer) will compute soft shadows from the quad light. Other renderers +will just sample the center of the quad light, which results in hard +shadows. + +#### HDRI Light + +The HDRI light is a textured light source surrounding the scene and +illuminating it from infinity. It is created by passing the type string +"`hdri`" to `ospNewLight`. In addition to the [parameter +`intensity`](#lights) the HDRI light supports the following special +parameters: + + ------------ ----- -------------------------------------------------- + Type Name Description + ------------ ----- -------------------------------------------------- + vec3f(a) up up direction of the light in world-space + + vec3f(a) dir direction to which the center of the texture will + be mapped to (analog to [panoramic camera]) + + OSPTexture2D map environment map in latitude / longitude format + ------------ ----- -------------------------------------------------- + : Special parameters accepted by the HDRI light. + +![Orientation and Mapping of an HDRI Light.][imgHDRILight] + +Note that the currently only the [path tracer] supports the HDRI light. + +#### Ambient Light + +The ambient light surrounds the scene and illuminates it from infinity +with constant radiance (determined by combining the [parameters `color` +and `intensity`](#lights)). It is created by passing the type string +"`ambient`" to `ospNewLight`. + +Note that the [SciVis renderer] uses ambient lights to control the color +and intensity of the computed ambient occlusion (AO). + +#### Emissive Objects + +The [path tracer] will consider illumination by [geometries] which have +a light emitting material assigned (for example the [Luminous] +material). + +### Materials + +Materials describe how light interacts with surfaces, they give objects +their distinctive look. To let the given renderer create a new material +of given type `type` call + + OSPMaterial ospNewMaterial2(const char *renderer_type, const char *material_type); + +The call returns `NULL` if the material type is not known by the +renderer type, or else an `OSPMaterial` handle to the created material. The +handle can then be used to assign the material to a given geometry with + + void ospSetMaterial(OSPGeometry, OSPMaterial); + +#### OBJ Material + +The OBJ material is the workhorse material supported by both the [SciVis +renderer] and the [path tracer]. It offers widely used common properties +like diffuse and specular reflection and is based on the [MTL material +format](http://paulbourke.net/dataformats/mtl/) of Lightwave's OBJ scene +files. To create an OBJ material pass the type string "`OBJMaterial`" to +`ospNewMaterial2`. Its main parameters are + + Type Name Default Description + ------------- --------- ---------- ----------------------------------------- + vec3f Kd white 0.8 diffuse color + vec3f Ks black specular color + float Ns 10 shininess (Phong exponent), usually in [2–10^4^] + float d opaque opacity + vec3f Tf black transparency filter color + OSPTexture2D map_Bump NULL normal map + ------------- --------- ---------- ----------------------------------------- + : Main parameters of the OBJ material. + +In particular when using the path tracer it is important to adhere to +the principle of energy conservation, i.e. that the amount of light +reflected by a surface is not larger than the light arriving. Therefore +the path tracer issues a warning and renormalizes the color parameters +if the sum of `Kd`, `Ks`, and `Tf` is larger than one in any color +channel. Similarly important to mention is that almost all materials of +the real world reflect at most only about 80% of the incoming light. So +even for a white sheet of paper or white wall paint do better not set +`Kd` larger than 0.8; otherwise rendering times are unnecessary long and +the contrast in the final images is low (for example, the corners of a +white room would hardly be discernible, as can be seen in the figure +below). + +![Comparison of diffuse rooms with 100% reflecting white paint (left) +and realistic 80% reflecting white paint (right), which leads to in +higher overall contrast. Note that exposure has been adjusted to achieve +similar brightness levels.][imgDiffuseRooms] + +If present, the color component of [geometries] is also used for the +diffuse color `Kd` and the alpha component is also used for the opacity +`d`. + +Note that currently only the path tracer implements colored transparency +with `Tf`. + +Normal mapping can simulate small geometric features via the texture +`map_Bump`. The normals $n$ in the normal map are wrt. the local +tangential shading coordinate system and are encoded as $½(n+1)$, thus a +texel $(0.5, 0.5, 1)$^[respectively $(127, 127, 255)$ for 8\ bit +textures] represents the unperturbed shading normal $(0, 0, 1)$. Because +of this encoding an sRGB gamma [texture] format is ignored and normals +are always fetched as linear from a normal map. Note that the +orientation of normal maps is important for a visually consistent look: +by convention OSPRay uses a coordinate system with the origin in the +lower left corner; thus a convexity will look green towards the top of +the texture image (see also the example image of a normal map). If this +is not the case flip the normal map vertically or invert its green +channel. + +![Normal map representing an exalted square pyramidal +frustum.][imgNormalMap] + +All parameters (except `Tf`) can be textured by passing a [texture] +handle, prefixed with "`map_`". The fetched texels are multiplied by the +respective parameter value. Texturing requires [geometries] with texture +coordinates, e.g. a [triangle mesh] with `vertex.texcoord` provided. +The color textures `map_Kd` and `map_Ks` are typically in one of the +sRGB gamma encoded formats, whereas textures `map_Ns` and `map_d` are +usually in a linear format (and only the first component is used). +Additionally, all textures support [texture transformations]. + +![Rendering of a OBJ material with wood textures.][imgMaterialOBJ] + +#### Metal + +The [path tracer] offers a physical metal, supporting changing roughness +and realistic color shifts at edges. To create a Metal material pass the +type string "`Metal`" to `ospNewMaterial2`. Its parameters are + + -------- ---------- ---------- -------------------------------------------- + Type Name Default Description + -------- ---------- ---------- -------------------------------------------- + vec3f[] ior Aluminium [data] array of spectral samples of complex + refractive index, each entry in the form + (wavelength, eta, k), ordered by wavelength + (which is in nm) + + vec3f eta RGB complex refractive index, real part + + vec3f k RGB complex refractive index, imaginary part + + float roughness 0.1 roughness in [0–1], 0 is perfect mirror + -------- ---------- ---------- -------------------------------------------- + : Parameters of the Metal material. + +The main appearance (mostly the color) of the Metal material is +controlled by the physical parameters `eta` and `k`, the +wavelength-dependent, complex index of refraction. These coefficients +are quite counterintuitive but can be found in [published +measurements](https://refractiveindex.info/). For accuracy the index of +refraction can be given as an array of spectral samples in `ior`, each +sample a triplet of wavelength (in nm), eta, and k, ordered +monotonically increasing by wavelength; OSPRay will then calculate the +Fresnel in the spectral domain. Alternatively, `eta` and `k` can also be +specified as approximated RGB coefficients; some examples are given in +below table. + + Metal eta k + -------------- ----------------------- ----------------- + Ag, Silver (0.051, 0.043, 0.041) (5.3, 3.6, 2.3) + Al, Aluminium (1.5, 0.98, 0.6) (7.6, 6.6, 5.4) + Au, Gold (0.07, 0.37, 1.5) (3.7, 2.3, 1.7) + Cr, Chromium (3.2, 3.1, 2.3) (3.3, 3.3, 3.1) + Cu, Copper (0.1, 0.8, 1.1) (3.5, 2.5, 2.4) + -------------- ----------------------- ----------------- + : Index of refraction of selected metals as approximated RGB + coefficients, based on data from https://refractiveindex.info/. + +The `roughness` parameter controls the variation of microfacets and thus +how polished the metal will look. The roughness can be modified by a +[texture] `map_roughness` ([texture transformations] are supported as +well) to create interesting edging effects. + +![Rendering of golden Metal material with textured +roughness.][imgMaterialMetal] + +#### Alloy + +The [path tracer] offers an alloy material, which behaves similar to +[Metal], but allows for more intuitive and flexible control of the +color. To create an Alloy material pass the type string "`Alloy`" to +`ospNewMaterial2`. Its parameters are + + Type Name Default Description + ------ ---------- ---------- -------------------------------------------- + vec3f color white 0.9 reflectivity at normal incidence (0 degree) + vec3f edgeColor white reflectivity at grazing angle (90 degree) + float roughness 0.1 roughness, in [0–1], 0 is perfect mirror + ------ ---------- ---------- -------------------------------------------- + : Parameters of the Alloy material. + +The main appearance of the Alloy material is controlled by the parameter +`color`, while `edgeColor` influences the tint of reflections when seen +at grazing angles (for real metals this is always 100% white). If +present, the color component of [geometries] is also used for +reflectivity at normal incidence `color`. As in [Metal] the `roughness` +parameter controls the variation of microfacets and thus how polished +the alloy will look. All parameters can be textured by passing a +[texture] handle, prefixed with "`map_`"; [texture transformations] are +supported as well. + +![Rendering of a fictional Alloy material with textured +color.][imgMaterialAlloy] + +#### Glass + +The [path tracer] offers a realistic a glass material, supporting +refraction and volumetric attenuation (i.e. the transparency color +varies with the geometric thickness). To create a Glass material pass +the type string "`Glass`" to `ospNewMaterial2`. Its parameters are + + Type Name Default Description + ------ -------------------- -------- ----------------------------------- + float eta 1.5 index of refraction + vec3f attenuationColor white resulting color due to attenuation + float attenuationDistance 1 distance affecting attenuation + ------ -------------------- -------- ----------------------------------- + : Parameters of the Glass material. + +For convenience, the rather counterintuitive physical attenuation +coefficients will be calculated from the user inputs in such a way, that +the `attenuationColor` will be the result when white light traveled +trough a glass of thickness `attenuationDistance`. + +![Rendering of a Glass material with orange +attenuation.][imgMaterialGlass] + +#### ThinGlass + +The [path tracer] offers a thin glass material useful for objects with +just a single surface, most prominently windows. It models a very thin, +transparent slab, i.e. it behaves as if a second, virtual surface is +parallel to the real geometric surface. The implementation accounts for +multiple internal reflections between the interfaces (including +attenuation), but neglects parallax effects due to its (virtual) +thickness. To create a such a thin glass material pass the type string +"`ThinGlass`" to `ospNewMaterial2`. Its parameters are + + Type Name Default Description + ------ -------------------- -------- ----------------------------------- + float eta 1.5 index of refraction + vec3f attenuationColor white resulting color due to attenuation + float attenuationDistance 1 distance affecting attenuation + float thickness 1 virtual thickness + ------ -------------------- -------- ----------------------------------- + : Parameters of the ThinGlass material. + +For convenience the attenuation is controlled the same way as with the +[Glass] material. Additionally, the color due to attenuation can be +modulated with a [texture] `map_attenuationColor` ([texture +transformations] are supported as well). If present, the color component +of [geometries] is also used for the attenuation color. The `thickness` +parameter sets the (virtual) thickness and allows for easy exchange of +parameters with the (real) [Glass] material; internally just the ratio +between `attenuationDistance` and `thickness` is used to calculate the +resulting attenuation and thus the material appearance. + +![Rendering of a ThinGlass material with red +attenuation.][imgMaterialThinGlass] + +![Example image of a colored window made with textured attenuation of +the ThinGlass material.][imgColoredWindow] + + +#### MetallicPaint + +The [path tracer] offers a metallic paint material, consisting of a base +coat with optional flakes and a clear coat. To create a MetallicPaint +material pass the type string "`MetallicPaint`" to `ospNewMaterial2`. Its +parameters are listed in the table below. + + Type Name Default Description + ------ ------------ ---------- ---------------------------------- + vec3f baseColor white 0.8 color of base coat + float flakeAmount 0.3 amount of flakes, in [0–1] + vec3f flakeColor Aluminium color of metallic flakes + float flakeSpread 0.5 spread of flakes, in [0–1] + float eta 1.5 index of refraction of clear coat + ------ ------------ ---------- ---------------------------------- + : Parameters of the MetallicPaint material. + +The color of the base coat `baseColor` can be textured by a [texture] +`map_baseColor`, which also supports [texture transformations]. If +present, the color component of [geometries] is also used for the color +of the base coat. parameter `flakeAmount` controls the proportion of +flakes in the base coat, so when setting it to 1 the `baseColor` will +not be visible. The shininess of the metallic component is governed by +`flakeSpread`, which controls the variation of the orientation of the +flakes, similar to the `roughness` parameter of [Metal]. Note that the +effect of the metallic flakes is currently only computed on average, +thus individual flakes are not visible. + +![Rendering of a MetallicPaint material.][imgMaterialMetallicPaint] + +#### Luminous + +The [path tracer] supports the Luminous material which emits light +uniformly in all directions and which can thus be used to turn any +geometric object into a light source. It is created by passing the type +string "`Luminous`" to `ospNewMaterial2`. The amount of constant radiance +that is emitted is determined by combining the general parameters of +lights: [`color` and `intensity`](#lights). + +![Rendering of a yellow Luminous material.][imgMaterialLuminous] + +### Texture + +To create a new 2D texture of size `size` (in pixels) and with the given +format and flags use + + OSPTexture2D ospNewTexture2D(const vec2i &size, + const OSPTextureFormat, + void *source = NULL, + const uint32_t textureCreationFlags = 0); + +The call returns `NULL` if the texture could not be created with the +given parameters, or else an `OSPTexture2D` handle to the created +texture. The supported texture formats are: + + Name Description + ------------------- ---------------------------------------------------------- + OSP_TEXTURE_RGBA8 8\ bit [0–255] linear components red, green, blue, alpha + OSP_TEXTURE_SRGBA 8\ bit sRGB gamma encoded color components, and linear alpha + OSP_TEXTURE_RGBA32F 32\ bit float components red, green, blue, alpha + OSP_TEXTURE_RGB8 8\ bit [0–255] linear components red, green, blue + OSP_TEXTURE_SRGB 8\ bit sRGB gamma encoded components red, green, blue + OSP_TEXTURE_RGB32F 32\ bit float components red, green, blue + OSP_TEXTURE_R8 8\ bit [0–255] linear single component + OSP_TEXTURE_R32F 32\ bit float single component + ------------------- ---------------------------------------------------------- + : Supported texture formats by `ospNewTexture2D`, i.e. valid constants + of type `OSPTextureFormat`. + +The texel data addressed by `source` starts with the texels in the lower +left corner of the texture image, like in OpenGL. Similar to [data] +buffers the texel data can be shared by the application by specifying +the `OSP_TEXTURE_SHARED_BUFFER` flag. Per default a texture fetch is +filtered by performing bi-linear interpolation of the nearest 2×2 +texels; if instead fetching only the nearest texel is desired (i.e. no +filtering) then pass the `OSP_TEXTURE_FILTER_NEAREST` flag. Both texture +creating flags can be combined with a bitwise OR. + +### Texture Transformations + +All materials with textures also offer to manipulate the placement of +these textures with the help of texture transformations. If so, this +convention shall be used. The following parameters (prefixed with +"`texture_name.`") are combined into one transformation matrix: + + Type Name Description + ------ ------------ ------------------------------------------------------ + vec4f transform interpreted as 2×2 matrix (linear part), column-major + float rotation angle in degree, counterclock-wise, around center + vec2f scale enlarge texture, relative to center (0.5, 0.5) + vec2f translation move texture in positive direction (right/up) + ------ ------------ ------------------------------------------------------ + : Parameters to define texture coordinate transformations. + +The transformations are applied in the given order. Rotation, scale and +translation are interpreted "texture centric", i.e. their effect seen by +an user are relative to the texture (although the transformations are +applied to the texture coordinates). + +### Cameras + +To create a new camera of given type `type` use + + OSPCamera ospNewCamera(const char *type); + +The call returns `NULL` if that type of camera is not known, or else an +`OSPCamera` handle to the created camera. All cameras accept these +parameters: + + Type Name Description + --------- ----------- ------------------------------------------ + vec3f(a) pos position of the camera in world-space + vec3f(a) dir main viewing direction of the camera + vec3f(a) up up direction of the camera + float nearClip near clipping distance + vec2f imageStart start of image region (lower left corner) + vec2f imageEnd end of image region (upper right corner) + --------- ----------- ------------------------------------------ + : Parameters accepted by all cameras. + +The camera is placed and oriented in the world with `pos`, `dir` and +`up`. OSPRay uses a right-handed coordinate system. The region of the +camera sensor that is rendered to the image can be specified in +normalized screen-space coordinates with `imageStart` (lower left +corner) and `imageEnd` (upper right corner). This can be used, for +example, to crop the image, to achieve asymmetrical view frusta, or to +horizontally flip the image to view scenes which are specified in a +left-handed coordinate system. Note that values outside the default +range of [0–1] are valid, which is useful to easily realize overscan or +film gate, or to emulate a shifted sensor. + +#### Perspective Camera + +The perspective camera implements a simple thinlens camera for +perspective rendering, supporting optionally depth of field and stereo +rendering, but no motion blur. It is created by passing the type string +"`perspective`" to `ospNewCamera`. In addition to the [general +parameters](#cameras) understood by all cameras the perspective camera +supports the special parameters listed in the table below. + + ----- ---------------------- ----------------------------------------- + Type Name Description + ----- ---------------------- ----------------------------------------- + float fovy the field of view (angle in degree) of + the frame's height + + float aspect ratio of width by height of the frame + + float apertureRadius size of the aperture, controls the depth + of field + + float focusDistance distance at where the image is sharpest + when depth of field is enabled + + bool architectural vertical edges are projected to be + parallel + + int stereoMode 0: no stereo (default), + 1: left eye, + 2: right eye, + 3: side-by-side + + float interpupillaryDistance distance between left and right eye when + stereo is enabled + ----- ---------------------- ----------------------------------------- + : Parameters accepted by the perspective camera. + +Note that when setting the `aspect` ratio a non-default image region +(using `imageStart` & `imageEnd`) needs to be regarded. + +In architectural photography it is often desired for aesthetic reasons +to display the vertical edges of buildings or walls vertically in the +image as well, regardless of how the camera is tilted. Enabling the +`architectural` mode achieves this by internally leveling the camera +parallel to the ground (based on the `up` direction) and then shifting +the lens such that the objects in direction `dir` are centered in the +image. If finer control of the lens shift is needed use `imageStart` & +`imageEnd`. Because the camera is now effectively leveled its image +plane and thus the plane of focus is oriented parallel to the front of +buildings, the whole façade appears sharp, as can be seen in the example +images below. + +![Example image created with the perspective camera, featuring depth of +field.][imgCameraPerspective] + +![Enabling the `architectural` flag corrects the perspective projection +distortion, resulting in parallel vertical +edges.][imgCameraArchitectural] + +![Example 3D stereo image using `stereoMode` side-by-side.][imgCameraStereo] + +#### Orthographic Camera + +The orthographic camera implements a simple camera with orthographic +projection, without support for depth of field or motion blur. It is +created by passing the type string "`orthographic`" to `ospNewCamera`. +In addition to the [general parameters](#cameras) understood by all +cameras the orthographic camera supports the following special +parameters: + + Type Name Description + ------ ------- ------------------------------------------------------------ + float height size of the camera's image plane in y, in world coordinates + float aspect ratio of width by height of the frame + ------ ------- ------------------------------------------------------------ + : Parameters accepted by the orthographic camera. + +For convenience the size of the camera sensor, and thus the extent of +the scene that is captured in the image, can be controlled with the +`height` parameter. The same effect can be achieved with `imageStart` +and `imageEnd`, and both methods can be combined. In any case, the +`aspect` ratio needs to be set accordingly to get an undistorted image. + +![Example image created with the orthographic camera.][imgCameraOrthographic] + +#### Panoramic Camera + +The panoramic camera implements a simple camera without support for +motion blur. It captures the complete surrounding with a latitude / +longitude mapping and thus the rendered images should best have a ratio +of 2:1. A panoramic camera is created by passing the type string +"`panoramic`" to `ospNewCamera`. It is placed and oriented in the scene +by using the [general parameters](#cameras) understood by all cameras. + +![Latitude / longitude map created with the panoramic camera.][imgCameraPanoramic] + +### Picking + +To get the world-space position of the geometry (if any) seen at [0–1] +normalized screen-space pixel coordinates `screenPos` use + + void ospPick(OSPPickResult*, OSPRenderer, const vec2f &screenPos); + +The result is returned in the provided `OSPPickResult` struct: + + typedef struct { + vec3f position; // the position of the hit point (in world-space) + bool hit; // whether or not a hit actually occurred + } OSPPickResult; + +Note that `ospPick` considers exactly the same camera of the given +renderer that is used to render an image, thus matching results can be +expected. If the camera supports depth of field then the center of the +lens and thus the center of the circle of confusion is used for picking. + + +Framebuffer +----------- + +The framebuffer holds the rendered 2D image (and optionally auxiliary +information associated with pixels). To create a new framebuffer object +of given size `size` (in pixels), color format, and channels use + + OSPFrameBuffer ospNewFrameBuffer(const vec2i &size, + const OSPFrameBufferFormat format = OSP_FB_SRGBA, + const uint32_t frameBufferChannels = OSP_FB_COLOR); + +The parameter `format` describes the format the color buffer has _on the +host_, and the format that `ospMapFrameBuffer` will eventually return. +Valid values are: + + Name Description + --------------- ------------------------------------------------------------- + OSP_FB_NONE framebuffer will not be mapped by the application + OSP_FB_RGBA8 8\ bit [0–255] linear component red, green, blue, alpha + OSP_FB_SRGBA 8\ bit sRGB gamma encoded color components, and linear alpha + OSP_FB_RGBA32F 32\ bit float components red, green, blue, alpha + --------------- ------------------------------------------------------------- + : Supported color formats of the framebuffer that can be passed to + `ospNewFrameBuffer`, i.e. valid constants of type + `OSPFrameBufferFormat`. + +The parameter `frameBufferChannels` specifies which channels the +framebuffer holds, and can be combined together by bitwise OR from the +values of `OSPFrameBufferChannel` listed in the table below. + + Name Description + ---------------- ----------------------------------------------------------- + OSP_FB_COLOR RGB color including alpha + OSP_FB_DEPTH euclidean distance to the camera (_not_ to the image plane) + OSP_FB_ACCUM accumulation buffer for progressive refinement + OSP_FB_VARIANCE estimate of the current variance if OSP_FB_ACCUM is also present, see [rendering] + ---------------- ----------------------------------------------------------- + : Framebuffer channels constants (of type `OSPFrameBufferChannel`), + naming optional information the framebuffer can store. These values + can be combined by bitwise OR when passed to `ospNewFrameBuffer` or + `ospClearFrameBuffer`. + +If a certain channel value is _not_ specified, the given buffer channel +will not be present. Note that ospray makes a very clear distinction +between the _external_ format of the framebuffer and the internal one: +The external format is the format the user specifies in the `format` +parameter; it specifies what color format OSPRay will eventually +_return_ the framebuffer to the application (when calling +`ospMapFrameBuffer`): no matter what OSPRay uses internally, it will +simply return a 2D array of pixels of that format, with possibly all +kinds of reformatting, compression/decompression, etc, going on +in-between the generation of the _internal_ framebuffer and the mapping +of the externally visible one. + +In particular, `OSP_FB_NONE` is a perfectly valid pixel format for a +framebuffer that an application will never map. For example, an +application driving a display wall may well generate an intermediate +framebuffer and eventually transfer its pixel to the individual displays +using an `OSPPixelOp` [pixel operation]. + +A framebuffer can be freed again using + + void ospFreeFrameBuffer(OSPFrameBuffer); + +Because OSPRay uses reference counting internally the framebuffer may +not immediately be deleted at this time. + +The application can map the given channel of a framebuffer – and thus +access the stored pixel information – via + + const void *ospMapFrameBuffer(OSPFrameBuffer, + const OSPFrameBufferChannel = OSP_FB_COLOR); + +Note that only `OSP_FB_COLOR` or `OSP_FB_DEPTH` can be mapped. The +origin of the screen coordinate system in OSPRay is the lower left +corner (as in OpenGL), thus the first pixel addressed by the returned +pointer is the lower left pixel of the image. + +A previously mapped channel of a framebuffer can be unmapped by passing +the received pointer `mapped` to + + void ospUnmapFrameBuffer(const void *mapped, OSPFrameBuffer); + +The individual channels of a framebuffer can be cleared with + + void ospFrameBufferClear(OSPFrameBuffer, const uint32_t frameBufferChannels); + +When selected, `OSP_FB_COLOR` will clear the color buffer to black +`(0, 0, 0, 0)`, `OSP_FB_DEPTH` will clear the depth buffer to `inf`, +`OSP_FB_ACCUM` will clear the accumulation buffer to black, resets the +accumulation counter `accumID` and also clears the variance buffer (if +present) to `inf`. + +### Pixel Operation {-} + +Pixel operations are functions that are applied to every pixel that +gets written into a framebuffer. Examples include post-processing, +filtering, blending, tone mapping, or sending tiles to a display wall. +To create a new pixel operation of given type `type` use + + OSPPixelOp ospNewPixelOp(const char *type); + +The call returns `NULL` if that type is not known, or else an +`OSPPixelOp` handle to the created pixel operation. + +To set a pixel operation to the given framebuffer use + + void ospSetPixelOp(OSPFrameBuffer, OSPPixelOp); + +#### Tone Mapper + +The tone mapper is a pixel operation which implements a generic filmic tone +mapping operator. It approximates the Academy Color Encoding System (ACES) +by default. The tone mapper is created by passing the type string "`tonemapper`" +to `ospNewPixelOp`. The tone mapping curve can be customized using the +parameters listed in the table below. + + ----- ---------- -------- ----------------------------------------- + Type Name Default Description + ----- --------- -------- ----------------------------------------- + float contrast 1.6773 contrast (toe of the curve); typically is + in [1-2] + + float shoulder 0.9714 highlight compression (shoulder of the + curve); typically is in [0.9-1] + + float midIn 0.18 mid-level anchor input; default is 18% + gray + + float midOut 0.18 mid-level anchor output; default is 18% + gray + + float hdrMax 11.0785 maximum HDR input that is not clipped + ----- --------- -------- ----------------------------------------- + : Parameters accepted by the tone mapper. + + +Rendering +--------- + +To render a frame into the given framebuffer with the given renderer use + + float ospRenderFrame(OSPFrameBuffer, OSPRenderer, + const uint32_t frameBufferChannels = OSP_FB_COLOR); + +The third parameter specifies what channel(s) of the framebuffer is +written to^[This is currently not implemented, i.e. all channels of +the framebuffer are always updated.]. What to render and how to +render it depends on the renderer's parameters. If the framebuffer +supports accumulation (i.e. it was created with `OSP_FB_ACCUM`) then +successive calls to `ospRenderFrame` will progressively refine the +rendered image. If additionally the framebuffer has an `OSP_FB_VARIANCE` +channel then `ospRenderFrame` returns an estimate of the current +variance of the rendered image, otherwise `inf` is returned. The +estimated variance can be used by the application as a quality indicator +and thus to decide whether to stop or to continue progressive rendering. diff --git a/doc/compilation.md b/doc/compilation.md new file mode 100644 index 0000000000..f2466cc965 --- /dev/null +++ b/doc/compilation.md @@ -0,0 +1,154 @@ +Building OSPRay from Source +=========================== + +The latest OSPRay sources are always available at the [OSPRay GitHub +repository](http://github.com/ospray/ospray).

The Example +Viewer uses the ImGui library for user interface controls and is +based on a prototype OSPRay scenegraph interface where nodes can +be viewed and edited interactively. +Updates to scenegraph nodes update OSPRay state automatically +through the scenegraph viewer which +is enabled by pressing 'g'. + +### Exploring the Scene +The GUI shows the entire state of the program under the root scenegraph node. +Expanding nodes down to explore and edit the scene is possible, for example a +material parameter may be found under renderer->world->mesh->material->Kd. +Updates to values will be automatically propagated to the next render. Individual +nodes can be easily found using the "Find Node" section, which will find nodes +with a given name based on the input string. Scene objects can also be selected +with the mouse by shift-left clicking in the viewer. + +Click on nodes to expand their children, +whose values can be set by dragging or double clicking and typing in values. +You can also add new nodes where appropriate: for +example, when "lights" is expanded right clicking on "lights" and selecting +create new node and typing +in a light type, such as "PointLight", will add it to the scene. Similarly, +right clicking on "world" and creating an "Importer" node will add a new +scene importer from a file. Changing the filename to an appropriate file +will load the scene and propagate the resulting state. Exporting +and importing the scenegraph is only partially supported at the moment through +"ospsg" files. Currently, any nodes with Data members will break this functionality, +however right clicking and selecting export on the camera or lights nodes for instance +will save out their respective state which can be imported on the command line. +ExampleViewer also functions as an OSPRay state debugger – invalid +values will be shown in red up the hierarchy and won't change the viewer +until corrected. + +### Volume Rendering +Volumes are loaded into the viewer just as a mesh is. Volume appearance is modified +according to the transfer function, which will show up in a popup window on the GUI after +pressing 'g'. Click and drag across the transfer function to set opacity values, and selecting +near the bottom of the editable transfer function widget sets the opacity to zero. The colors +themselves can only be modified by selecting from the dropdown menu 'ColorMap' or +importing and exporting json colors. The range that the transfer function operates +on can be modified on the scenegraph viewer. + +### ExampleViewer Controls +* 'g' - toggle scenegraph display +* 'q' - quit +* Left click and drag to rotate +* Right click and drag or mouse wheel to zoom in +and out. +* Mouse-Wheel click will pan the camera. +* Control-Left clicking on an object will select a model and all of its children +which will be displayed in the +* Shift-Left click on an object will zoom into that part of the scene and set +the focal distance. + +### CommandLine Options +* Running './ospExampleViewer -help' will bring up a list of commandline options. +These options allow you to load files, run animations, modify any scenegraph state, +and many other functions. See the demos page for examples. +* Supported file importers currently include: obj, ply, x3d, vtu, osp, ospsg, xml (rivl), +points, xyz. + + +Distributed Viewer +------------------ + +The application `ospDistribViewerDemo` demonstrates how to write a +distributed SciVis style interactive renderer using the distributed MPI +device. Note that because OSPRay uses sort-last compositing it is up to +the user to ensure that the data distribution across the nodes is +suitable. Specifically, each nodes' data must be convex and disjoint. +This renderer supports multiple volumes and geometries per node. To +ensure they are composited correctly you specify a list of bounding +regions to the model, within these regions can be arbitrary +volumes/geometries and each rank can have as many regions as needed. As +long as the regions are disjoint/convex the data will be rendered +correctly. In this demo we either generate a volume, or load a RAW +volume file if one is passed on the commandline. + +### Loading a RAW Volume + +To load a RAW volume you must specify the filename (`-f `), the +data type (`-dtype `), the dimensions (`-dims `) and the +value range for the transfer function (`-range `). For example, +to run on the [CSAFE dataset from the demos +page](http://www.ospray.org/demos.html#csafe-heptane-gas-dataset) you +would pass the following arguments: + + mpirun -np ./ospDistribViewerDemo \ + -f /csafe-heptane-302-volume.raw \ + -dtype uchar -dims 302 302 302 -range 0 255 + +The volume file will then be chunked up into an `x×y×z` grid such that +$n = xyz$. See `loadVolume` in [gensv/generateSciVis.cpp] for an +example of how to properly load a volume distributed across ranks with +correct specification of brick positions and ghost voxels for +interpolation at boundaries. If no volume file data is passed a volume +will be generated instead, in that case see `makeVolume`. + +### Geometry + +The viewer can also display some randomly generated sphere geometry if +you pass `-spheres ` where `n` is the number of spheres to generate +per-node. These spheres will be generated inside the bounding box of the +region's volume data. + +In the case that you have geometry crossing the boundary of nodes and +are replicating it on both nodes to render (ghost zones, etc.) the +region will be used by the renderer to clip rays against allowing to +split the object between the two nodes, with each rendering half. This +will keep the regions rendered by each rank disjoint and thus avoid any +artifacts. For example, if a sphere center is on the border between two +nodes, each would render half the sphere and the halves would be +composited to produce the final complete sphere in the image. + +### App-initialized MPI + +Passing the `-appMPI` flag will have the application initialize MPI +instead of letting OSPRay do it internally when creating the MPI +distributed device. In this case OSPRay will not finalize MPI when +cleaning up the device, allowing the application to use OSPRay for some +work, shut it down and recreate everything later if needed for +additional computation, without accidentally shutting down its MPI +communication. + +### Interactive Viewer + +Rank 0 will open an interactive window with GLFW and display the +rendered image. When the application state needs to update (e.g. camera +or transfer function changes), this information is broadcasted out to +the other nodes to update their scene data. + +Demos +----- + +Several ready-to-run demos, models and data sets for OSPRay can be found +at the [OSPRay Demos and Examples] page. diff --git a/doc/filter-latex.py b/doc/filter-latex.py new file mode 100644 index 0000000000..5072f9d325 --- /dev/null +++ b/doc/filter-latex.py @@ -0,0 +1,73 @@ +# 1. convert tables to use 'tabu' +# 2. always add hypertargets, before headings, to workaround issue #2719 +# Based on Wagner Macedo's filter.py posted at +# https://groups.google.com/forum/#!msg/pandoc-discuss/RUC-tuu_qf0/h-H3RRVt1coJ +import pandocfilters as pf + +def latex(s): + return pf.RawBlock('latex', s) + +def inlatex(s): + return pf.RawInline('latex', s) + +def tbl_caption(s): + return pf.Para([inlatex(r'\caption{')] + s + [inlatex(r'}')]) + +def tbl_alignment(a, w): + aligns = { + "AlignDefault": 'l', + "AlignLeft": 'l', + "AlignCenter": 'c', + "AlignRight": 'r', + } + s = ''; + for i in range(len(a)): + s += 'X[%.3f,' % -w[i] + aligns[a[i]['t']] + ']' + return s; + +def tbl_headers(s): + result = s[0][0]['c'][:] + for i in range(1, len(s)): + result.append(inlatex(' & ')) + result.extend(s[i][0]['c']) + result.append(inlatex(r'\\' '\n')) + return pf.Para(result) + +def tbl_contents(s): + result = [] + for row in s: + para = [] + for col in row: + if col: + para.extend(col[0]['c']) + para.append(inlatex(' & ')) + result.extend(para) + result[-1] = inlatex(r'\\' '\n') + return pf.Para(result) + +def do_filter(k, v, f, m): + if k == "Table": + w = v[2] + if sum(w) == 0: + w = [1 for e in w] + wd = '' + ha = r'\centering' + else: + wd = '*' + ha = r'\raggedright' + return [latex(r'\begin{table'+wd+'}[!h]'), + tbl_caption(v[0]), + latex(ha), + latex(r'\begin{tabu} spread 0pt {' + tbl_alignment(v[1], w) + '}'), + latex(r'\toprule'), + tbl_headers(v[3]), + latex(r'\midrule'), + tbl_contents(v[4]), + latex(r'\bottomrule' '\n' r'\end{tabu}'), + latex(r'\end{table'+wd+'}')] + if k == "Header": + return [latex(r'\hypertarget{' + v[1][0] + r'}{}'), + pf.Header(v[0], v[1], v[2])] + +if __name__ == "__main__": + pf.toJSONFilter(do_filter) diff --git a/doc/fiu_comparison.md b/doc/fiu_comparison.md new file mode 100644 index 0000000000..72b89a3220 --- /dev/null +++ b/doc/fiu_comparison.md @@ -0,0 +1,28 @@ +FIU Dataset: Shadows and Ambient Occlusion vs OpenGL-like local shading +======================================================================= + +(click on images to see higher-res versions) + +[![](demos/fiu/fiu-gl-small.jpg)](demos/fiu/fiu-gl.png) + +FIU with local (OpenGL-like) Shading +: Without shadows and/or ambient occlusion (i.e., using a OpenGL-like + local shading model), the FIU dataset looks like this. + +\ +[![](demos/fiu/fiu-obj-small.jpg)](demos/fiu/fiu-obj.png) + +FIU with ray traced shadows +: Simply adding shadows already greatly enhances the user's perception + of depth (e.g., the relative positions of streamlines and base + geometry, the actual shape of the geometry, etc). + +\ +[![](demos/fiu/fiu-ao-small.jpg)](demos/fiu/fiu-ao.png) + +FIU with OSPRay's Ambient Occlusion Renderer +: Ambient Occlusion further increases perception of depth.

You can then inspect the CMake value of `MPI_LIBRARY` to +make sure that CMake found your MPI build environment correctly. + +This will result in an OSPRay module being built. To enable using it, +applications will need to either link `libospray_module_mpi`, or call + + ospLoadModule("mpi"); + +before initializing OSPRay. + +Modes of Using OSPRay's MPI Features +------------------------------------ + +OSPRay provides two ways of using MPI to scale up rendering: offload and +distributed. + +### Offload Rendering + +The "offload" rendering mode is where a single (not-distributed) calling +application treats the OSPRay API the same as with local rendering. +However, OSPRay uses multiple MPI connected nodes to evenly distribute +frame rendering work, where each node contains a full copy of all scene +data. This method is most effective for scenes which can fit into +memory, but are very expensive to render: for example, path tracing with +many samples-per-pixel is very compute heavy, making it a good situation +to use the offload feature. This can be done with any application which +already uses OSPRay for local rendering without the need for any code +changes. + +When doing MPI offload rendering, applications can optionally enable +dynamic load balancing, which can be beneficial in certain contexts. +This load balancing refers to the distribution of tile rendering work +across nodes: thread-level load balancing on each node is still dynamic +with the thread tasking system. The options for enabling/controlling the +dynamic load balacing features on the `mpi_offload` device are found in +the table below, which can be changed while the application is running. +Please note that these options will likely only pay off for scenes which +have heavy rendering load (e.g. path tracing a non-trivial scene) and +have a lot of variance in how expensive each tile is to render. + + Type Name Default Description + ----- -------------------- -------- -------------------------------------- + bool dynamicLoadBalancer false whether to use dynamic load balancing + ----- -------------------- -------- -------------------------------------- + : Parameters specific to the `mpi_offload` device + +### Distributed Rendering + +The "distributed" rendering mode is where a MPI distributed application +(such as a scientific simulation) uses OSPRay collectively to render +frames. In this case, the API expects all calls (both created objects +and parameters) to be the same on every application rank, except each +rank can specify arbitrary geometries and volumes. Each renderer will +have its own limitations on the topology of the data (i.e. overlapping +data regions, concave data, etc.), but the API calls will only differ +for scene objects. Thus all other calls (i.e. setting camera, creating +framebuffer, rendering frame, etc.) will all be assumed to be identical, +but only rendering a frame and committing the model must be in +lock-step. This mode targets using all available aggregate memory for +very large scenes and for "in-situ" visualization where the data is +already distributed by a simulation app. + +Running an Application with the "offload" Device +------------------------------------------------ + +As an example, our sample viewer can be run as a single application +which offloads rendering work to multiple MPI processes running on +multiple machines. + +The example apps are setup to be launched in two different setups. In +either setup, the application must initialize OSPRay with the offload +device. This can be done by creating an "`mpi_offload`" device and +setting it as the current device (via the `ospSetCurrentDevice()` +function), or passing either "`--osp:mpi`" or "`--osp:mpi-offload`" as a +command line parameter to `ospInit()`. Note that passing a command line +parameter will automatically call `ospLoadModule("mpi")` to load the MPI +module, while the application will have to load the module explicitly if +using `ospNewDevice()`. + +### Single MPI Launch + +OSPRay is initialized with the `ospInit()` function call which takes +command line arguments in and configures OSPRay based on what it finds. +In this setup, the app is launched across all ranks, but workers will +never return from `ospInit()`, essentially turning the application into +a worker process for OSPRay. Here's an example of running the +ospVolumeViewer data-replicated, using `c1`-`c4` as compute nodes and +`localhost` the process running the viewer itself: + + mpirun -perhost 1 -hosts localhost,c1,c2,c3,c4 ./ospExampleViewer --osp:mpi + +### Separate Application&Worker Launches + +The second option is to explicitly launch the app on rank 0 and worker +ranks on the other nodes. This is done by running `ospray_mpi_worker` on +worker nodes and the application on the display node. Here's the same +example above using this syntax: + + mpirun -perhost 1 -hosts localhost ./ospExampleViewer --osp:mpi \ + : -hosts c1,c2,c3,c4 ./ospray_mpi_worker + +This method of launching the application and OSPRay worker separately +works best for applications which do not immediately call `ospInit()` in +their `main()` function, or for environments where application +dependencies (such as GUI libraries) may not be available on compute +nodes. + +Running an Application with the "distributed" Device +---------------------------------------------------- + +Applications using the new distributed device should initialize OSPRay +by creating (and setting current) an "`mpi_distributed`" device or pass +`"--osp:mpi-distributed"` as a command line argument to `ospInit()`. +Note that due to the semantic differences the distributed device gives +the OSPRay API, it is not expected for applications which can already +use the offload device to correctly use the distributed device without +changes to the application. + +The following additional parameter can be set on the `mpi_distributed` +device. + + ------- ----------------- ---------------------------------------------- + Type Name Description + ------- ----------------- ---------------------------------------------- + `void*` worldCommunicator A pointer to the `MPI_Comm` which should be + used as OSPRay's world communicator. This will + set how many ranks OSPRay should expect to + participate in rendering. The default is + `MPI_COMM_WORLD` where all ranks are expected + to participate in rendering. + ------ ------------ ---------------------------------------------------- + : Parameters for the `mpi_distributed` device. + +By setting the `worldCommunicator` parameter to a different communicator +than `MPI_COMM_WORLD` the client application can tune how OSPRay is run +within its processes. The default uses `MPI_COMM_WORLD` and thus expects +all processes to also participate in rendering, thus if a subset of processes +do not call collectives like `ospRenderFrame` the application would hang. + +For example, an MPI parallel application may be +run with one process per-core, however OSPRay is multithreaded and will +perform best when run with one process per-node. By splitting `MPI_COMM_WORLD` +the application can create a communicator with one rank per-node to then +run OSPRay on one process per-node. The remaining ranks on each node +can then aggregate their data to the OSPRay process for rendering. + diff --git a/doc/news.md b/doc/news.md new file mode 100644 index 0000000000..fd058000b3 --- /dev/null +++ b/doc/news.md @@ -0,0 +1,269 @@ +News, Updates, and Announcements +================================ + +Mar 7, 2018: Version v1.5.0 now released on GitHub +--------------------------------------------------- + +New release version 1.5.0 is now available on the [OSPRay GitHub +page](https://github.com/ospray/OSPRay/releases/v1.5.0). + + +Jan 10, 2018: Version v1.4.3 now released on GitHub +--------------------------------------------------- + +New release version 1.4.3 is now available on the [OSPRay GitHub +page](https://github.com/ospray/OSPRay/releases/v1.4.3). + + +Nov 28, 2017: Version v1.4.2 now released on GitHub +--------------------------------------------------- + +New release version 1.4.2 is now available on the [OSPRay GitHub +page](https://github.com/ospray/OSPRay/releases/v1.4.2). + + +Nov 10, 2017: Version v1.4.1 now released on GitHub +--------------------------------------------------- + +New release version 1.4.1 is now available on the [OSPRay GitHub +page](https://github.com/ospray/OSPRay/releases/v1.4.1). + + +Sept 29, 2017: Version v1.4.0 now released on GitHub +---------------------------------------------------- + +New release version 1.4.0 is now available on the [OSPRay GitHub +page](https://github.com/ospray/OSPRay/releases/v1.4.0). + + +July 7, 2017: Version v1.3.1 now released on GitHub +--------------------------------------------------- + +New release version 1.3.1 is now available on the [OSPRay GitHub +page](https://github.com/ospray/OSPRay/releases/v1.3.1). + + +June 2, 2017: Version v1.3.0 now released on GitHub +--------------------------------------------------- + +New release version 1.3.0 is now available on the [OSPRay GitHub +page](https://github.com/ospray/OSPRay/releases/v1.3.0). + +Mar 27, 2017: VisIt & OSPRay/SWR +-------------------------------- + +[Pre-built binaries][1] for +[VisIt](https://wci.llnl.gov/simulation/computer-codes/visit) to run +with OSPRay or [SWR](http://openswr.org/) are available, see [here for +instructions][1]. + +[1]: http://web.eecs.utk.edu/~ahota/visitospray/binary.html + +Mar 13, 2017: Version v1.2.1 now released on GitHub +---------------------------------------------------- + +New release version 1.2.1 is now available on the [OSPRay GitHub +page](https://github.com/ospray/OSPRay/releases/v1.2.1). + +Feb 9, 2017: Version v1.2.0 now released on GitHub +---------------------------------------------------- + +New release version 1.2.0 is now available on the [OSPRay GitHub +page](https://github.com/ospray/OSPRay/releases/v1.2.0). + +Nov 30, 2016: Version v1.1.2 now released on GitHub +---------------------------------------------------- + +New release version 1.1.2 is now available on the [OSPRay GitHub +page](https://github.com/ospray/OSPRay/releases/v1.1.2). + +Oct 2016: OSPRay at IEEE Vis +---------------------------- + +The paper "[OSPRay – A CPU Ray Tracing Framework for Scientific +Visualization](http://www.sdvis.org/ospray/download/talks/IEEEVis2016_OSPRay_paper.pdf)" +(49MB, [smaller version](http://www.sdvis.org/ospray/download/talks/IEEEVis2016_OSPRay_paper_small.pdf) +1.8MB) has been accepted at IEEE Vis.

The Scenegraph is currently in Alpha mode and will change frequently. It is not +yet recommended for critical production work. + +The scenegraph is the basis of our exampleViewer which consists of a superset of OSPRay objects represented in a graph hierarchy (currently a tree). This +graph functions as a hierarchical specification for scene properties and a self-managed update graph. The +scenegraph infrastructure includes many convenience functions for templated traversals, queries of +state and child state, automated updates, and timestamped modifications to underlying state. + +The scenegraph nodes closely follow the dependencies of existing OSPRay API internals, ie +a sg::Renderer has a "model" child, which in turn has a "TriangleMesh", which in turn has a child +named "vertex" similar to how you may set the "vertex" parameter on the osp::TriangleMesh which in +turn is added to an OSPModel object which is set as the model on the OSPRenderer. The scenegraph +is a supserset of OSPRay functionality so there isn't a direct 1:1 mapping between the scenegraph +hierarchy in all cases, however it is kept as close as possible. This makes the scene graph viewer +in ospExampleViewer a great way to understand OSPRay state. + + +### Hierarchy Structure +The root of the scenegraph is based on sg::Renderer. The scenegraph can be created by +``` +auto renderer = sg::createNode("renderer", "Renderer"); +``` +which automatically creates child nodes for necessary OSPRay state. To update and commit all state and render +a single function is provided which can be called with: +``` +renderer.renderFrame(renderer["frameBuffer"].nodeAs); +``` +Values can be set using: +``` +renderer["spp"] = 16; +``` +The explore the full set of nodes, simply launch the exampleViewer and traverse through the +GUI representation of all scenegraph nodes. + +### Traversals +The scenegraph contains a set of builtin traversals as well as modular visitor functors for +implementing custom passes over the scenegraph. The required traversals are handled for you +by default within the renderFrame function on the renderer. For any given node there are two phases +to a traversal operation, pre and post traversal of the nodes children. preTraversal initializes +node state and objects and sets the current traversal context with appropriate state. For instance, +sg::Model will create a new OSPModel object, set its value to that object, +and set sg::RenderContext.currentOSPModel to its own value. After preTraversal is finished, the children +of sg::Model are processed in a similar fashion and now use the modified context. In postTraversal, +sg::Model will commit the changes that its children have potentially set and it will pop its modifications +from the current context. This behavior is replicated for every scenegraph node and enables children +to act on parent state without specific implementations from the parent node. An example of this are the +sg::NodeParam nodes which are containers for values to be set on OSPObjects, such as a float value. This +is put on the scenegraph with a call to: +``` +renderer["lights"]["sun"].createChild("intensity", "float", 0.3f); +``` +This call accesses the child named "lights" on the renderer, and in turn the child named "sun". +This child then gets its own child of a newly created node with the name "intensity" of type "float" +with a value of 0.3f. When committed, this node will call ospSet1f with the node value on the current +OSPObject on the context which is set by the parent. If you were to create a custom light called "MyLight" +and had a float parameter called "flickerFreq", a similar line would be used without requiring any additional +changes in the scenegraph internals beyond registering the new light class. Known parameters such as +floats will also show up in the exampleViewerGUI without requiring any additional code beyond adding them to +the scenegraph and the internal implementation in OSPRay. + +The base passes required to utilize the scenegraph +include verification, commit, and render traversals. Every node in the scenegraph has a valid state +which needs to be set before operating on the node. Nodes may have custom qualifications for validity, +but by default they are set through valid_ flags on the scenegraph Node for things like whitelists +and range checks. Once verified, Commit traverses the scenegraph and commits scenegraph state to +OSPRay. Commits are timestamped, so re-committing will only have any affect if a dependent child +has been modified requiring a new commit. Because of this, each node does not have to track if it is +valid or if anything in the scene has been modified, as commit will only be called on that node if those +are already true. By default invalid nodes with throw exceptions, however this can be turned off which enables +the program to keep running. In the exampleViewer GUI, invalid nodes will be marked in red but the previously +committed state will keep rendering until the invalid state is corrected. + +For examples of implementing custom traversals, see the sg/visitors folder.

The Scenegraph is currently in Alpha +mode and will change frequently. It is not yet recommended for critical +production work.** + +The scenegraph is the basis of our exampleViewer which consists of a +superset of OSPRay objects represented in a graph hierarchy (currently a +tree). This graph functions as a hierarchical specification for scene +properties and a self-managed update graph. The scenegraph +infrastructure includes many convenience functions for templated +traversals, queries of state and child state, automated updates, and +timestamped modifications to underlying state. + +The scenegraph nodes closely follow the dependencies of existing OSPRay +API internals, ie a sg::Renderer has a "model" child, which in turn has +a "TriangleMesh", which in turn has a child named "vertex" similar to +how you may set the "vertex" parameter on the osp::TriangleMesh which in +turn is added to an OSPModel object which is set as the model on the +OSPRenderer. The scenegraph is a supserset of OSPRay functionality so +there isn't a direct 1:1 mapping between the scenegraph hierarchy in all +cases, however it is kept as close as possible. This makes the scene +graph viewer in ospExampleViewer a great way to understand OSPRay state. + +Hierarchy Structure +------------------- + +The root of the scenegraph is based on sg::Renderer. The scenegraph can +be created by + + auto renderer = sg::createNode("renderer", "Renderer"); + +which automatically creates child nodes for necessary OSPRay state. To +update and commit all state and render a single function is provided +which can be called with: + + renderer.renderFrame(renderer["frameBuffer"].nodeAs); + +Values can be set using: + + renderer["spp"] = 16; + +The explore the full set of nodes, simply launch the exampleViewer and +traverse through the GUI representation of all scenegraph nodes. + +Traversals +---------- + +The scenegraph contains a set of builtin traversals as well as modular +visitor functors for implementing custom passes over the scenegraph. The +required traversals are handled for you by default within the +renderFrame function on the renderer. For any given node there are two +phases to a traversal operation, pre and post traversal of the nodes +children. preTraversal initializes node state and objects and sets the +current traversal context with appropriate state. For instance, +sg::Model will create a new OSPModel object, set its value to that +object, and set sg::RenderContext.currentOSPModel to its own value. +After preTraversal is finished, the children of sg::Model are processed +in a similar fashion and now use the modified context. In postTraversal, +sg::Model will commit the changes that its children have potentially set +and it will pop its modifications from the current context. This +behavior is replicated for every scenegraph node and enables children to +act on parent state without specific implementations from the parent +node. An example of this are the sg::NodeParam nodes which are +containers for values to be set on OSPObjects, such as a float value. +This is put on the scenegraph with a call to: + + renderer["lights"]["sun"].createChild("intensity", "float", 0.3f); + +This call accesses the child named "lights" on the renderer, and in turn +the child named "sun". This child then gets its own child of a newly +created node with the name "intensity" of type "float" with a value of +0.3f. When committed, this node will call ospSet1f with the node value +on the current OSPObject on the context which is set by the parent. If +you were to create a custom light called "MyLight" and had a float +parameter called "flickerFreq", a similar line would be used without +requiring any additional changes in the scenegraph internals beyond +registering the new light class. Known parameters such as floats will +also show up in the exampleViewerGUI without requiring any additional +code beyond adding them to the scenegraph and the internal +implementation in OSPRay. + +The base passes required to utilize the scenegraph include verification, +commit, and render traversals. Every node in the scenegraph has a valid +state which needs to be set before operating on the node. Nodes may have +custom qualifications for validity, but by default they are set through +valid\_ flags on the scenegraph Node for things like whitelists and +range checks. Once verified, Commit traverses the scenegraph and commits +scenegraph state to OSPRay. Commits are timestamped, so re-committing +will only have any affect if a dependent child has been modified +requiring a new commit. Because of this, each node does not have to +track if it is valid or if anything in the scene has been modified, as +commit will only be called on that node if those are already true. By +default invalid nodes with throw exceptions, however this can be turned +off which enables the program to keep running. In the exampleViewer GUI, +invalid nodes will be marked in red but the previously committed state +will keep rendering until the invalid state is corrected. + +For examples of implementing custom traversals, see the sg/visitors +folder. Here is an example of a visitor that collects all nodes with a +given name: + + struct GatherNodesByName : public Visitor + { + GatherNodesByName(const std::string &_name); + + bool operator()(Node &node, TraversalContext &ctx) override; + + std::vector> results(); + + private: + std::string name; + std::vector> nodes; + }; + + // Inlined definitions //////////////////////////////////////////////////// + + inline GatherNodesByName::GatherNodesByName(const std::string &_name) + : name(_name) + { + } + + inline bool GatherNodesByName::operator()(Node &node, TraversalContext &) + { + if (utility::longestBeginningMatch(node.name(), this->name) == this->name) { + auto itr = std::find_if( + nodes.begin(), + nodes.end(), + [&](const std::shared_ptr &nodeInList) { + return nodeInList.get() == &node; + } + ); + + if (itr == nodes.end()) + nodes.push_back(node.shared_from_this()); + } + + return true; + } + + inline std::vector> GatherNodesByName::results() + { + return nodes;// TODO: should this be a move (i.e. reader 'consumes')? + } + +Thread Safety +------------- + +The scenegraph is only thread safe for accessing and setting values on +nodes.

The +required traversals are handled for you by default within the +renderFrame function on the renderer. For any given node there are two +phases to a traversal operation, pre and post traversal of the nodes +children. preTraversal initializes node state and objects and sets the +current traversal context with appropriate state. For instance, +sg::Model will create a new OSPModel object, set its value to that +object, and set sg::RenderContext.currentOSPModel to its own value. +After preTraversal is finished, the children of sg::Model are processed +in a similar fashion and now use the modified context. In postTraversal, +sg::Model will commit the changes that its children have potentially set +and it will pop its modifications from the current context. This +behavior is replicated for every scenegraph node and enables children to +act on parent state without specific implementations from the parent +node. An example of this are the sg::NodeParam nodes which are +containers for values to be set on OSPObjects, such as a float value. +This is put on the scenegraph with a call to: + + renderer["lights"]["sun"].createChild("intensity", "float", 0.3f); + +This call accesses the child named "lights" on the renderer, and in turn +the child named "sun". This child then gets its own child of a newly +created node with the name "intensity" of type "float" with a value of +0.3f.

If +you were to create a custom light called "MyLight" and had a float +parameter called "flickerFreq", a similar line would be used without +requiring any additional changes in the scenegraph internals beyond +registering the new light class.
