  • Method for non-planar specular reflections in hybrid ray tracing
    Patent number: 10699468
    Abstract: The present invention teaches a real-time hybrid ray tracing method for non-planar specular reflections. The high complexity of a non-planar surface is reduced to low complexity of multiple small planar surfaces. Advantage is taken of the planar nature of triangles that comprise building blocks of a non-planar surface. All secondary rays bouncing from a given surface triangle toward object triangles keep a close direction to each other. A collective control of secondary rays is enabled by this closeness and by decoupling secondary rays from primary rays. The result is high coherence of secondary rays.

  • MULTIPROCESSING SYSTEM FOR PATH TRACING OF BIG DATA
    Publication number: 20200175743
    Abstract: A path tracing system in which the traversal task is distributed between one global acceleration structure, which is central in the system, and multiple local acceleration structures, distributed among cells, of high locality and of autonomous processing. Accordingly, the centrality of the critical resource of accelerating structure is reduced, lessening bottlenecks, while improving parallelism.
