Abstract:
To eliminate unnecessary ray packet-triangle intersection tests, we check for separation of two convex objects: a triangle and a frustum containing intersections of rays with a leaf node of an acceleration structure. We show a performance improvement that is proportional to the ratio of lengths of average leaf edge to triangle edge, which opens new possibilities for creation of better acceleration structures.
