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.

Abstract: Accelerating structure for hybrid ray tracing is characterized by high locality, wherein scene changes are updated locally in one of its hierarchies, without effecting other locations in the structure. Reconstructions of accelerating structures of prior art are replaced by low-cost updates. The efficiency of traversals is improved by a double step traversal.

Abstract: The present invention teaches a real-time hybrid ray tracing system 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 a high coherence of secondary rays.
