N-Body Simulator

This simulates the gravitational interaction of a bunch of stars using Python and GLSL. It is an "N-Body simulator". By using the GPU, it is reasonably performant compared to a CPU-only version.

The simulator uses/depends on:

• Python 3.7 - 3.9 (Not 3.10 because of a shapely library dependency)
• Compute Shaders (Needs OpenGL 4.3+)
• Arcade Library

A longer tutorial is available on the Arcade website.

You can adjust the num_stars parameter if your hardware is running this too slow. There are a couple different initial star setups you can try.
