Abstract
A technique for performing ray tracing is provided. The technique is applied to a bounding volume hierarchy which comprises a plurality of oriented bounding boxes. The oriented bounding boxes are emulated by translating each oriented bounding box into two or more volumes. After the emulating step, the bounding volume hierarchy is traversed. In some examples, the regular shapes or volumes comprise axis-aligned bounding boxes, cubes or anisotropic rectangles. In one example, the emulating step is performed at run-time using dedicated hardware.
