Hi guys, Anybody has some experience with ray sorting on CPU based path tracers? I'm working on a CPU-only path tracer/bidirectional path tracer based on Embree. I was thinking about implementing ray reordering and packet tracing for incoherent rays to increase performance (since Embree supports pac...
