Abstract
A technique for performing ray tracing operations is provided. The technique includes traversing through a bounding volume hierarchy to an instance node; performing an instance node transform using common circuitry; traversing to a leaf node of the bounding volume hierarchy; and performing an intersection test for the leaf node using the common circuitry.
