Abstract: Systems and methods for high performance ray tracing scene graphs are provided by constructing a complex three dimensional special structure of sectors and nodes. Sectors are regions of space which can take any shape or size in three dimensional space. The non tree-based space partitioning structure allows rays to traverse the spatial structure to directly resolve the primitives they intersect. Traversal cost is efficiently minimized by constructing large sectors to contain empty space and constructing relatively smaller sectors to contain the geometric primitives. Each sector contains information associated with each of its surfaces including whether the surface leads to another sector or a node.
