ALEXANDRIA, Va., Nov. 6 -- United States Patent no. 12,462,467, issued on Nov. 4, was assigned to Apple Inc. (Cupertino, Calif.).
"Hardware acceleration for motion blur with ray tracing" was invented by Christopher A. Burns (Austin, Texas).
According to the abstract* released by the U.S. Patent & Trademark Office: "Techniques are disclosed relating to ray tracing and motion blur in graphics processors. In some embodiments, ray intersection accelerator circuitry is configured to perform traversal operations for an acceleration data structure (ADS) that includes hierarchical bounding volumes, where the ADS includes a first node that specifies: first coordinates of a bounding volume at a first motion blur time and second coordinates of the b...
