Abstract
One or more rotated bounding volumes are generated for one or more nodes of a bounding volume hierarchy (BVH). Volume intersection ray tracing tests are then be performed using the rotated bounding volumes with the aim of reducing the number of calculations required relative to an original, non-rotated bounding volume. Rotated bounding volumes are selected from a plurality of candidate rotations, and selection of one of the candidate rotations are based on surface areas, such as minimum total surface areas, of bounding volumes corresponding to each of the candidate rotations. In order to minimize data storage and increase performance, a number of candidate rotations may be limited to a predetermined set of rotations.
