Abstract
A circuit arrangement, program product and circuit arrangement utilize the known view orientation for an image frame to be rendered to reposition an Accelerated Data Structure (ADS) used during rendering to optimize the generation and/or use of the ADS, e.g., by transforming a scene from which an image frame is rendered to orient the scene relative to the view orientation prior to generating the ADS. A scene may be transformed, for example, to orient the view orientation within a single octant of the scene, with additional processing resources assigned to that octant to ensure sufficient processing resources are devoted to processing the primitives within the view orientation.
