Abstract:
1. A method comprising: obtaining data describing a physical material, wherein the data describing the physical material includes a plurality of palettized images of a first sample of the physical material, wherein each of the palettized images comprises a respective reflected image of the first sample of the physical material reflected by a respective mirror of a plurality of mirrors; receiving a shading request to shade a particular point in a computer graphics (CG) representation of the physical material from a rendering engine, wherein the request identifies a mapping position of the particular point, a view direction at the mapping position, and a light direction at the mapping position; calculating a direct lighting color at the mapping position using the plurality of palettized images; calculating an indirect lighting color at the mapping position using the data describing the physical material; generating a final color at the mapping position by combining the direct lighting color and the indirect lighting color; and providing the final color to the rendering engine for use in rendering the CG representation of the physical material.
