Abstract:
An apparatus and method are described for performing a distance test in a ray tracing system. For example, one embodiment of a graphics processing apparatus comprises: a ray tracing traversal/intersection unit to identify two or more ray-surface intersections, each of the ray-surface intersections being assigned a unique hit point identifier (ID); and a distance testing module to disambiguate the order of the ray-surface intersections using the hit point ID if the two or more of the ray-surface intersections share the same distance.

Claim (Index 1):
A method for traversing bounding volume hierarchies (BVHs) comprising a plurality of BVH nodes comprising:\n (a) queuing a plurality of untraversed nodes and a current closest hitpoint for a ray; (b) identifying a closest node of the untraversed nodes; (c) if the closest node is not further than the current closest hitpoint and is a leaf node, then identifying an intersection for the closest node and accepting the intersection only if it is closer than the current hitpoint; and (d) if the closest node is not further than the current closest hitpoint and is not a leaf node, then enqueuing child nodes of the closest node that intersect the ray along with a respective distance for each child node.
