Accelerated Data Structure Optimization Based Upon View Orientation

A circuit arrangement, program product and method utilize the known view orientation for an image frame to be rendered to optimize the generation and/or use of an Accelerated Data Structure (ADS) used in physical rendering-based image processing. In particular, it has been found that while geometry primitives that are not within a view orientation generally cannot be culled from a scene when a physical rendering technique such as ray tracing is performed, those primitives nonetheless have a smaller impact on the resulting image frame, and as a result, less processing resources can be applied to such primitives, leaving greater processing resources available for processing those primitives that are located within the view orientation, and thereby improving overall rendering performance.
