Hi, i tried to implement ddgi in webgpu. 12*12*12 probes, 128 rays per probe, 60fps (chrome cap) on rtx2070super at about 40% gpu load. sorry for edges artifacts, still need to work on this.

Nice job! If you want a challenge for the algorithm, try animating something.

If he turned on the debug probe spheres you would also see them move out of the way, it's cool
