I hacked in a weighted stochastic method into a WebGPU solution[0] and it worked surprisingly well. Essentially, given each pixel of a splat, pick a pseudo-random number from zero to one and if it’s lower than the alpha value for the pixel, draw over whatever is in the frame buffer at full opacity.
The next step I wanted to try was to super-sample (eg render at double resolution) and linearly down sample. I imagine this would give a slightly noisy result that I think would be pretty visually pleasing.
