Particle Life simulation in browser using WebGPU
If you don't care about the explanation and want a direct link to the simulation, here you go. You might know that I'm a sucker for physics simulations, and particle simulations in particular.
However, Vulkan, which is the supposed alternative modern API, takes 1000 lines of setup work just to show a triangle on screen, without even any vertex buffers & attributes. That's rather inconvenient, so I always round it up to the closest even number: this way, the result is always in the same binSize array, while an extra prefix sum iteration would simply copy one buffer into the other automatically (look what happens with the code when step >= array.size). into an HDR rgba16float texture, then composited onto the screen (actually, onto an HTML canvas) using ACES tone-mapping and some blue-noise dithering to hide banding resulting from dark colors on the edge of the glow.
