Finally!!! I got the radix sort working! The screen shot doesn’t look like much, but if you notice the bar on the bottom, the colors are generally grouped together and are perfectly stable. I had really struggled with getting this to work correctly as I’m not exactly the most experienced with compute shaders (or I should say was, now I know more about them than I need to). I had reached out to the shader labs discord even (thanks to them btw, they helped with a workgroup dispatching bug I had) and ran about every test possible to eliminate any possible race conditions/out of bounds errors. Then comes gemini to save the day. Apparently, I really should have done some more research into atomics in the past since even though they are meant to be stable, they are not perfect in the slightest, so I was basically attempting to do a radix sort without stable ranking (which is what it needs to achieve its insane parallelism and speed) and yeah it works now. BVH time (which should not take long to setup, the radix is normally the hard part), then true RTX features (not just voxelizations) like raytraced reflections and idk I might add a path tracing option since I’ve made a PT on shadertoy before and it was super enjoyable to do.
