Abstract: An apparatus and method for extracting and using path shading coherence in a ray tracing architecture. For example, one embodiment of a graphics processing apparatus comprises: ray generation logic to generate a ray stream from one or more image tiles; ray sorting logic to sort the rays within the ray stream based on a material identifier (ID) associated with each of the rays to generate a sorted ray stream; and one or more shaders to perform shading operations on rays within the sorted ray stream in an order in which the rays are sorted within the sorted ray stream.
