US Patent Issued to ARM on July 7 for "Graphics texture mapping" (Norwegian Inventors)

ALEXANDRIA, Va., July 7 -- United States Patent no. 12,675,939, issued on July 7, was assigned to ARM Ltd. (Cambridge, Great Britain).

"Graphics texture mapping" was invented by Edvard Fielding (Trondheim, Norway) and Jorn Nystad (Trondheim, Norway).

According to the abstract* released by the U.S. Patent & Trademark Office: "When sampling a 3D texture using anisotropic filtering, an anisotropy direction along which to take samples in the texture is determined by determining reduced precision representations of the texture coordinate derivative vectors and using the reduced precision texture coordinate derivative vectors to determine a pair of vectors representing the directions of x and y axes for a 2D coordinate system on the plane in th...
