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.
gen_galaxies_colliding function
gen_random_space function
