Abstract

An apparatus and method are described for using tessellation hardware to generate bounding volume hierarchies (BVHs) and perform other ray tracing operations. For example, one embodiment of an apparatus comprises: a shader to output a plurality of tessellation factors and one or more input surfaces; and a tessellation circuit comprising first circuitry and/or logic to tesselate each input surface to generate a new set of primitives and second circuitry and/or logic to concurrently generate a bounding volume hierarchy (BVH) based on the new set of primitives.
