Abstract
A system and method for performing intersection testing of rays in a ray tracing system. The ray tracing system uses a hierarchical acceleration structure comprising a plurality of nodes, each identifying one or more elements for intersection testing. The system defines and updates progress information that identifies, for a ray, leaf nodes of the hierarchical acceleration structure which identify elements for which it is not yet known whether or not the ray interests.
