Claim:
A method of generating an accelerated data structure for use in physical rendering-based image processing, the method comprising: generating a textured bounding volume within a scene; and generating an accelerated data structure by processing a plurality of primitives disposed in the scene, including: storing a first subset of the plurality of primitives in the accelerated data structure; and mapping a second subset of the plurality of primitives to at least two surfaces of the textured bounding volume; wherein generating the textured bounding volume includes adding a first corresponding primitive for a first surface of the textured bounding volume and a second corresponding primitive for a second surface of the textured bounding volume to the accelerated data structure, wherein mapping the second subset of the plurality of primitives to at least two surfaces of the textured bounding volume includes projecting at least a first ray from an origin of a view orientation to map a first primitive among the plurality of primitives onto a first texture defined on the first corresponding primitive for the first surface of the textured bounding volume and projecting at least a second ray from the origin of the view orientation to map a second primitive among the plurality of primitives onto a second texture defined on the second corresponding primitive for the second surface of the textured bounding volume, wherein the method further comprises performing physical rendering based on the view orientation using the accelerated data structure such that an intersection test and texture lookup for the first or second corresponding primitive is performed in response to the first or second corresponding primitive being identified in the accelerated data structure when tracing a ray, and wherein the textured bounding volume encapsulates the second subset of the plurality of primitives such that the second subset of the plurality of primitives are disposed within the textured bounding volume.
