US Patent Issued to Nvidia on May 27 for "Motion vector optimization for multiple refractive and reflective interfaces" (California, Washington Inventors)

ALEXANDRIA, Va., June 17 -- United States Patent no. 12,315,064, issued on May 27, was assigned to Nvidia Corp. (Santa Clara, Calif.).

"Motion vector optimization for multiple refractive and reflective interfaces" was invented by Pawel Kozlowski (Truckee, Calif.) and Maksim Aizenshtein (Sammamish, Wash.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Systems and methods relate to the determination of accurate motion vectors, for rendering situations such as a noisy Monte Carlo integration where image object surfaces are at least partially translucent. To optimize the search for "real world" positions, this invention defines the background as first path vertices visible through multiple layers of refractive in...
