Getting rid of packets-efficient simd single-ray traversal using multi-branching bvhs

I Wald, C Benthin, S Boulos - 2008 IEEE Symposium on …, 2008 - ieeexplore.ieee.org
While contemporary approaches to SIMD ray tracing typically rely on traversing packets of
coherent rays through a binary data structure, we instead evaluate the alternative of …
