Abstract

A technique for performing a ray intersection test, the method comprising: receiving a request for an early termination ray intersection test for a ray; testing the ray against one or more early termination box nodes and one or more normal box nodes of a bounding volume hierarchy; and based on the test of the ray against the one or more early termination box nodes, determining whether to end traversal of the bounding volume hierarchy and determine whether the ray intersects geometry for the purpose of the ray intersection test.
