@Yann_LeGall @C010011012 real time version on shadertoy. it isn’t as good as path traced though, and ball rolling simulation isn’t possible afaik. shadertoy.com/view/33tfWM

based on an animation I saw by Dan Piker. Took me a while to figure out some of the edge cases. Also shout out to @C010011012 who has made several nice variations using shaders.
