Abstract

A technique for performing ray tracing operations is provided. The technique includes, in a first iteration of a ray traversal technique, traversing to an instance node of a bounding volume hierarchy; in a second iteration of the ray traversal technique that is subsequent to the first iteration, transforming a ray based on an instance transform of the instance node to generate a transformed ray; and in the second iteration, performing a ray-box intersection test for box node data of the instance node based on the transformed ray.
