Inventors include Barczak, Joshua David; Al-Qbaidi, Mohammed Ahmed Muneam; Mcallister, David Kirk; and Kensler, Andrew Erin.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: Systems and methods for ray intersection against primitives are described. Primitive data is encoded efficiently into arrays of fixed-size data blocks using a data format which can be directly consumed for ray traversal. Vertex data in a block is pre-quantized and stored using a fixed-bit quantization grid. Mesh connectivity is encoded using a triangle strips based on control values representing triangle interconnectivity, and a compressed index buffer storing indices for vertices in each strip. Primitives can alternatively be quantized to generate primitive packets, that are stored compactly in, with, or near a leaf node of an acceleration structure. Low-precision intersection testers test a ray simultaneously against primitives to find candidate triangles that require full-precision intersection. Primitives that generate an inconclusive result during low-precision testing are retested using full-precision testers to definitively determine ray-triangle hits or misses.
