MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202617091131 A) filed by Advanced Micro Devices, Inc. on July 27, 2026, for Systems And Methods For Detecting Ray Intersections With Displaced Micro-Meshes.
Inventors include Mcallister, David Kirk; Kensler, Andrew Erin; and Gruen, Holger.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A device that defines and uses a bounding volume for testing for ray intersections with a displaced micro-mesh. The bounding volume is indirectly based on a twisted prism composed of two triangles and three bilinear patches that bounds the displaced micro-mesh. Instead of detecting intersection with the bilinear patches directly, tetrahedrons that circumscribe the bilinear patches can be used instead. The two bases and the three tetrahedra make fourteen triangles. The device tests for potential intersection with the displaced micro-mesh by testing for an intersection with any of the fourteen triangles. Various other methods and systems are also disclosed.
