ALEXANDRIA, Va., Aug. 25 -- United States Patent no. 12,718,464, issued on Aug. 25, was assigned to Advanced Micro Devices Inc. (Santa Clara, Calif.).
"Neural network-based ray tracing" was invented by Shin Fujieda (Tokyo), Takahiro Harada (Santa Clara, Calif.) and Chih-Chen Kao (Munich).
According to the abstract* released by the U.S. Patent & Trademark Office: "A technique for performing ray tracing operations is provided. The technique includes traversing a bounding volume hierarchy for a ray to arrive at a bounding box without use of a neural network; perform a feature vector lookup using modified polar coordinates characterizing the ray relative to the bounding box to obtain a set of feature vectors; and obtaining output with the neu...
