PARALLELIZATION FOR RAYTRACING

Abstract:

A technique for performing ray tracing operations is provided. The technique includes performing bounding volume hierarchy ("BVH") traversal in multiple accelerated processing devices ("APDs"), utilizing bounding volume hierarchy data copies in memories local to the multiple APDs; rendering primitives determined to be intersected based on the BVH traversal, using geometry information and texture data spread across the memories local to the multiple APDs; and storing results of rendered primitives for a set of tiles assigned to the multiple APDs into tile buffers stored in APD memories local to the APDs.
