  • Techniques for ray cone tracing and texture filtering
    Patent number: 11756258
    Abstract: One embodiment of a method for computing a texture color includes tracing a ray cone through a graphics scene, determining a curvature of a first surface within the graphics scene at a point where the ray cone hits the first surface based on differential barycentric coordinates associated with the point, determining, based on the curvature of the first surface, a width of the ray cone at a subsequent point where the ray cone hits a second surface within the graphics scene, and computing a texture color based on the width of the ray cone.
    Type: Grant
    Filed: September 7, 2022
    Date of Patent: September 12, 2023
    Assignee: NVIDIA Corporation
    Inventors: Tomas Akenine-Moller, Jakub Boksansky, Oli Wright
