Abstract
Disclosed techniques relate to grouping rays during traversal of a spatially-organized acceleration data structure (e.g., a bounding volume hierarchy) for ray intersection processing. The grouping may provide temporal locality for accesses to bounding region data. In some embodiments, ray intersect circuitry is configured to group rays based on the node of the data structure that they target next. The ray intersect circuitry may select one or more groups of rays for issuance each clock cycle, e.g., to bounding region test circuitry.
