Abstract: Aspects comprise a ray tracing system based on data structure of a uniform grid of cells, and on local stencils in cells. The high traversal and construction costs of accelerating structures, typical to the prior art ray tracing, are greatly reduced. The stencils, generated in a preprocessing phase, hold visibility information, for a runtime use. Each cell achieves high locality, allowing improved parallel processing.

Abstract: Aspects comprise a ray tracing shadowing method based on the data structure of a uniform grid of cells, and on local stencils in cells. The high traversal and construction costs of accelerating structures are cut down. The object's visibility from the viewpoint and from light sources, as well as the primary workload and its distribution among cells, are gained in the preprocessing stage and cached in stencils for runtime use. In runtime, the use of stencils allows a complete locality at each cell, for load balanced parallel processing.

Abstract: Aspects comprise shadowing system as part of ray tracing. It is based on uniform grid of cells, and on local stencils in cells. The acceleration structures are abandoned along with high traversal and construction costs of these structures. The amount of intersection tests is cut down. The stencils are generated in the preprocessing stage and utilized in runtime. The relevant part of scene data, critical for shadowing of all visible intersection points in a cell, is registered in the local stencil map, as a volumetric data. The runtime use of stencils allows a complete locality at each cell, enhanced utilization of processing resources and load balancing of parallel processing.
