This abstract first appeared for US patent application 20250131638 titled 'TEMPORAL COHERENCE FOR RAY TRAVERSAL
Original Abstract Submitted
aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., a gpu. the apparatus may perform a ray traversal process for a second frame in a set of frames starting at a first node in a plurality of nodes, where a ray in the ray traversal process previously intersected a first primitive in a first frame, where the first primitive corresponds to a first node id. the apparatus may also detect whether the ray intersects the first primitive in the second frame. further, the apparatus may store the first node id for the first node based on the ray intersecting the first primitive in the second frame, or re-perform the ray traversal process for the second frame starting at a root node in the plurality of nodes based on the ray not intersecting the first primitive in the second frame.
