Adaptive Ray Packet Reordering Solomon Boulos† Ingo Wald� Carsten Benthin�†Stanford University � Intel CorporationFigure 1: Our three test scenes rendered with two bounces of diffuse path tracing and one light sample per bounce (six rays per path) at 64 paths per pixel. Our reordering method maintains high SIMD utilization even for these incoherent ray distributions, achieving 1.2M rays per second for the conference scene (far right) (1.5× faster than BVH packet traversal and single ray traversa
