Abstract

A method, computer readable medium, and system are disclosed for performing a texture level-of-detail approximation. The method includes the steps of identifying a scene to be rendered, projecting a ray passing through a pixel of a screen space, resulting in a first hit point at a geometry element within the scene, determining a footprint angle of the pixel, determining a curvature measure for the geometry element at the first hit point within the scene, computing a texture level of detail (LOD) approximation for a component of the scene, utilizing the footprint angle of the pixel and the curvature measure for the geometry element, and performing, utilizing a hardware processor, one or more rendering operations for the scene, utilizing the texture LOD approximation.
