Gravity Simulation

This program simulates the behaviour of objects in a 2D gravitational field. The simulation uses the Verlet integration method to solve the equation of motion of objects in the gravitational field.

Building and Running The Program

The program may be compiled for Windows using clang++ by simply running the CMake build command. Before the program may be run, the following must be done:

• the shader files must be copied from ./shaders to the directory in which the .exe file is located.
• csv file named sim.txt with data must be present in the .exe directory. The format of the csv file is position x, position y, velocity x, velocity y, mass.

Keybinds

There are a number of keybinds provided by the program:

• lmb (hold) - move the camera.
• scroll - zoom in and out.
• q - decrease simulation speed x2.
• w - increase simulation speed x2.
• r - toggle between run and single-step modes.
• s - step one simulation frame (if single-step mode is enabled).
• d - enable debug information logging.
• z - decrease the scale of rendered objects x2.
• x - increase the scale of rendered objects x2.
• t - toggle field rendering.
• 1, 2, 3, 4 - change field rendering method.

System Requirements

The program requires OpenGL 4.5.
