What are the system requirements to run this? Fairly 'standard' Linux system running Chrome here. "Sorry, there was an error starting the simulation Sorry, WebGPU is not supported on our device WiFi Solver may not be compatible with your device."

Earlier quoted context omitted.

Good question! This is actually a numerical solver for a few coupled partial differential equations - the method in this context (electromagnetism) is called FDTD. It's implemented as a WebGPU compute shader. You absolutely could do this using WebGL2 compute shaders too, but I thought it would be fun to try this newer API.

I don't understand what other type of solution is there to render on a gpu other than a numeric one? Here is a very basic shader for what you want: float freq1 = 2.0; float freq2 = 3.0; float amp = 0.5; pos.z += sin(pos.x * freq1 + uTime) * amp; pos.z += cos(pos.y * freq2 + uTime) * amp; gl_Position = projectionMatrix * modelViewMatrix * vec4(pos, 1.0);
