1. Install requirements: pip install -r requirements.txt
   • Vulkan might be required to run Taichi efficiently
2. Set Number of stars: Set taichi_gravity.py N value
3. Run: python taichi_render.py
4. Close the window to exit

The simulation has quirky controls configured in taichi_renderer.

• "Space": hold to pause
• "WASD": press to move the camera videogame style
• "Shift": Leave press to make the camera follow the mouse
• "P": Orbit the center with the camera on the Y axis (Right)
• "l","k": Orbit the center with the camera on the X axis (Up and Down respectively)
• "v": press to start recording every frame. (Frames would be saved as png in frames folder)
• "b": press to stop recording

Videos are maked frame by frame in the frames folder Run to make video:
ffmpeg -r 30 -i frame_%04d.png -c:v libx264 -pix_fmt yuv420p output.mp4 Or to add overlay text

ffmpeg -r 15 -i frame_%04d.png -vf "drawtext=text='N-Body simulation 40k stars':fontcolor=white:fontsize=24:x=10:y=10" -c:v libx264 -pix_fmt yuv420p output.mp4

Some simple tests to ensure the acceleration implementations are returning the same result.
