Start node determination for tree traversal in raytracing applications

摘要

At least one processor may organize a plurality of primitives within the hierarchical data structure. At least one processor may rasterize a plurality of bounding volumes associated with non-root nodes of the hierarchical data structure into an off-screen rendering target. At least one processor may determine a bounding volume at which the rays intersect from a plurality of bounding volumes. At least one processor may determine a non-root node of the hierarchical data structure associated with the bounding volume as a starting node in the hierarchical data structure for initiating traversal of the hierarchical data structure. At least one processor may traverse the hierarchical data structure starting from the start node to determine the primitives that the rays intersect.
