ALEXANDRIA, Va., Nov. 18 -- United States Patent no. 12,475,632, issued on Nov. 18, was assigned to Nvidia Corp. (Santa Clara, Calif.).
"Inverse transform sampling through ray tracing" was invented by Nathan Morrical (Salt Lake City).
According to the abstract* released by the U.S. Patent & Trademark Office: "High quality image rendering can be achieved in part by using inverse transform sampling to direct sampling toward regions of greater importance, such as regions with higher brightness values, to reduce noise and improve convergence. Inverse transform sampling can be achieved more efficiently by reformulating as a ray-tracing problem, using tree traversal units that can be accelerated. A geometric mesh can be generated based on a set...
