 ### Draco Compression
-To install the [Google Draco](https://google.github.io/draco/) compression the [DracoPy](https://github.com/seung-lab/DracoPy) library is needed. Because it is still under development, we just include it if the [extra](https://packaging.python.org/en/latest/tutorials/installing-packages/#installing-setuptools-extras) `draco` is specified.

 ### Limitations
-If draco compression is turned on, only **vertex** and **triangle** information is stored into the mesh. This is due to the fact that [DracoPy](https://github.com/seung-lab/DracoPy) does only support these two primitive values. At the moment we recommend to not use the internal compression, but convert the sequence into a glb file and later convert it using the [gltf-pipeline](https://github.com/CesiumGS/gltf-pipeline). This leads to way better compression and contains still all information parts:

 ### Animation
-To use the GLTF animation system to render the meshes in a sequence, it is possible to specify the framerate (default `24`) and set the animation flag. Volumesh will add an animation track which hides and shows the objects after each other using the glTF animation tools.
