Abstract
A circuit arrangement, program product and circuit arrangement utilize a textured bounding volume to reduce the overhead associated with generating and using an Accelerated Data Structure (ADS) in connection with physical rendering. In particular, a subset of the primitives in a scene may be mapped to surfaces of a bounding volume to generate textures on such surfaces that can be used during physical rendering. By doing so, the primitives that are mapped to the bounding volume surfaces may be omitted from the ADS to reduce the processing overhead associated with both generating the ADS and using the ADS during physical rendering, and furthermore, in many instances the size of the ADS may be reduced, thus reducing the memory footprint of the ADS, and often improving cache hit rates and reducing memory bandwidth.
