Abstract

High-quality rendering via ray tracing requires the tracing of many incoherent secondary rays. In order to accelerate the tracing of incoherent rays, we propose a simple sorting method to increase ray coherence. In this method, we use ray origin buckets and ray direction grids to reorder rays quickly. We implemented our approach on the Manta interactive ray tracer and achieved up to a 1.48× speedup.
