US Patent Issued to Nvidia on Oct. 28 for "Hash cell boundary shifting for light transport simulation systems and applications" (French Inventor)

ALEXANDRIA, Va., Oct. 28 -- United States Patent no. 12,456,261, issued on Oct. 28, was assigned to Nvidia Corp. (Santa Clara, Calif.).

"Hash cell boundary shifting for light transport simulation systems and applications" was invented by Pascal Gautron (Speracedes, France).

According to the abstract* released by the U.S. Patent & Trademark Office: "Systems and methods implement a technique for altering the shape of the cells by shifting coordinates of points along cell boundaries using a set of periodic functions. To avoid having cell boundaries along the scene surfaces, wavelengths of those periodic functions are selected so they are not a multiple of an original discretization. The coordinates may be shifted along different axes of the ...
