Abstract

In this paper we describe and evaluate an implementation of CPU-style
SIMD ray traversal on the GPU. We show how spreading moderately wide
BVHs (up to a branching factor of eight) across multiple threads in a
warp can improve performance while not requiring expensive
pre-processing. The presented ray-traversal method exhibits improved
traversal performance especially for increasingly incoherent rays.
