Abstract

Apparatus and method for preventing re-traversal of a prior path on a restart. For example, one embodiment of an apparatus comprises: a ray generator to generate a plurality of rays in a first graphics scene; a bounding volume hierarchy (BVH) generator to construct a BVH comprising a plurality of hierarchically arranged nodes, wherein the BVH comprises a specified number of child nodes at a current BVH level beneath a parent node in the hierarchy; traversal/intersection circuitry to traverse one or more of the rays through the hierarchically arranged nodes of the BVH to form a current traversal path and intersect the one or more rays with primitives contained within the nodes; and traversal tracking circuitry to maintain a path encoding array to store path data related to the current traversal path, the path data comprising an index of a currently traversed child node; wherein the traversal/intersection circuitry is to prevent one or more subsequent rays from re-intersecting primitives from which they originated and/or avoid re-traversing the current traversal path based on the path data in the path encoding array.
