US 12,602,856 B2 · Dicing oracle for texture space shading

Abstract

This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for a dicing oracle for texture space shading. A processor obtains an indication of a UV parameterization for each of a set of geometry units and a target number of pixels per region of the UV parameterization, where the UV parameterization includes a first set of UV coordinates for an object space. The processor renders the set of geometry units in order to obtain a second set of UV coordinates for a screen space and a set of derivatives for the second set of UV coordinates. The processor calculates a resolution for a mip region map based on the set of derivatives and the target number of pixels per region. The processor outputs an indication of the calculated resolution.
