Abstract: Hybrid ray tracing method for generating photorealistic reflections while keeping coherence of secondary rays. The coherence is achieved by decoupling secondary rays from primary rays, handling bundles of secondary rays with collective origin and collective destination, attaining high parallelism and high utilization of GPU.

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 disclosure describes a method of generating fast path traced physically correct reflections in a semi-reflective surface. Secondary rays, generated by GPU graphics pipeline, are randomly deviated from the principal direction.

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: A computer-based method for hybrid ray tracing to generate photorealistic reflections of objects on a non-planar reflective surface. Each triangle of the reflective surface is handled separately for secondary rays to generate its own physically correct reflection. A final gathering of partial reflections results in an aggregated non-planar surface reflection.

Abstract: The present invention teaches a real-time hybrid ray tracing method for non-planar specular reflections. The non-planar surface is handled by 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.
