Abstract
A hierarchical structure for accelerating ray tracing operations in scene rendering includes a plurality of geometry objects, and a single acceleration structure constructed over the collective plurality of geometry objects. Each geometry object includes primitives of a predefined type, whereby primitives within the plurality of geometry objects collectively define a geometry included within a region of the scene which is to be rendered. The single acceleration structure is operable for accelerating ray tracing operations for the primitives included within the plurality of geometry objects, and is constructed over the plurality of the geometry objects without an intervening bounding volume representation of the plurality of primitives included within the geometry objects.
