摘要： 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.

摘要： Systems, apparatuses and methods may provide for technology that identifies, at an image post-processor, unresolved surface data and identifies, at the image post-processor, control data associated with the unresolved surface data. Additionally, the technology may resolve, at the image post-processor, the unresolved surface data and the control data into a final image.

摘要： An apparatus and method for compressing ray tracing data prior to transmission between nodes. For example, one embodiment of an apparatus comprises: a first node comprising a first ray tracing engine, the first node communicatively coupled to a second node comprising a second ray tracing engine; first compression circuitry coupled to the first ray tracing engine, the first compression circuitry to perform compression on ray tracing data of the first ray tracing engine to produce a first compressed stream of ray tracing data; and interface circuitry to transmit the first compressed stream of ray tracing data from the first node to the second node.
