Abstract:
1. A method, implemented at least in part by a computing device, for rendering an object having light reflective properties, the method comprising: determining a destination viewing vector for rendering the object from a destination viewpoint; determining a set of source radiance environment maps each having an associated source viewing vector, each source viewing vector representing a different, specific viewpoint associated with the source radiance environment map, each source radiance environment map including information indicative of a light reflective property of the object and comprising texels that each represent a pre-integrated value of total reflected radiance; warping, on a per-texel basis, each source radiance environment map of the set of source radiance environment maps based on the destination viewing vector and the source viewing vector associated with the source radiance environment map; blending the warped source radiance environment maps to create a destination radiance environment map, and render the object.
