Simulating 30 Million Microbes in the Browser WebGPU gives the browser direct access to modern GPU capabilities — not just for rendering, but also for general-purpose computation through compute shaders. But how far can we actually push it? What happens if, instead of running a small compute demo, we try to build a full simulation with tens of millions of active objects? That is what I wanted to find out. Background For this experiment, I decided to revive an evo...
