OPACITY TEXTURE-DRIVEN TRIANGLE SPLITTING

Abstract:

Techniques for performing ray tracing operations are provided. The techniques include dividing a primitive of a scene to generate primitive portions; identifying, from the primitive portions, and based on an opacity texture, one or more opaque primitive portions and one or more invisible primitive portions; generating box nodes for a bounding volume hierarchy corresponding to the opaque primitive portions, but not the invisible primitive portions; and inserting the generated box nodes into the bounding volume hierarchy.
