WebGPU Physarum (Slime/Mold) Simulation

A Slime Simulator made using WebGPU + Javascript

Live Demo (250,000 agents)

Check WebGPU browser compatibility list before running the live demo.

• I first wrote this in WebGL 1.0, which was challenging due to the lack of compute shaders. It can, however, be simulated using the Ping-Pong technique and multiple textures. The code for my working WebGL 1.0 implementation is there above.

• Porting it all to WebGPU was a simple enough task due to the presence of compute pipelines.

TODO

1. Dynamic number of agents (In WebGPU buffers/textures cannot be resized).
2. Multiple Species and Evolution.
3. Control agents using image/video bitmasks.
