Abstract: An apparatus and method for performing BVH compression and decompression concurrently with stores and loads, respectively. For example, one embodiment comprises: bounding volume hierarchy (BVH) construction circuitry to build a BVH based on a set of input primitives, the BVH comprising a plurality of uncompressed coordinates; traversal/intersection circuitry to traverse one or more rays through the BVH and determine intersections with the set of input primitives using the uncompressed coordinates; store with compression circuitry to compress the BVH including the plurality of uncompressed coordinates to generate a compressed BVH with compressed coordinates and to store the compressed BVH to a memory subsystem; and load with decompression circuitry to decompress the BVH including the compressed coordinates to generate a decompressed BVH with the uncompressed coordinates and to load the decompressed BVH with uncompressed coordinates to a cache and/or a set of registers accessible by the traversal/intersection circuitry.

Abstract: An apparatus and method are described for performing a distance test in a ray tracing system. For example, one embodiment of a graphics processing apparatus comprises: a ray tracing traversal/intersection unit to identify two or more ray-surface intersections, each of the ray-surface intersections being assigned a unique hit point identifier (ID); and a distance testing module to disambiguate the order of the ray-surface intersections using the hit point ID if the two or more of the ray-surface intersections share the same distance.

Abstract: A first set of N samples is located along a ray through a volume in connection with a first frame. The first set of N samples is stored. A second set of N additional samples is located along the ray in connection with a second frame. Then the first and second sets of samples are accumulated.
