Abstract:
A technique for performing ray tracing operations is provided. The technique includes reading descendant-shared type metadata for a non-leaf node of a bounding volume hierarchy; identifying one or more culling types for a ray-intersection test for a ray; and determining whether to treat the non-leaf node as not intersected based on whether the one or more culling types includes at least one type specified by the descendant-shared type metadata.
