Abstract
There is provided an illumination rendering system and method for use by such a system. The system includes a system processor, a system memory, and an illumination rendering engine including a ray tracing unit stored in the system memory. The system processor is configured to execute the ray tracing unit to recognize a present classification of a light path traveling between a ray source and a ray receiver, and to identify a scattering type of a next scattering event corresponding to a ray on the light path. The system processor is also configured to execute the ray tracing unit to determine a next classification of the light path based on the present classification of the light path and the scattering type.
