Abstract
A technique for performing ray tracing operations is provided. The technique includes receiving a ray for an intersection test, testing the ray against boxes specified in a bounding volume hierarchy to eliminate one or more boxes or triangles from consideration, unpacking a triangle from a compressed triangle block of the bounding volume hierarchy, the compressed triangle block including two or more triangles that share at least one vertex, and testing the ray for intersection against at least one of the unpacked triangles.
