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.

A system, method, and computer program product are provided for GPU demand paging. In operation, input data is addressed in terms of a virtual address space. Additionally, the input data is organized into one or more pages of data. Further, the input data organized as the one or more pages of data is at least temporarily stored in a physical cache. In addition, access to the input data in the physical cache is facilitated.
