Abstract
Methods and systems for producing three-dimensional images of a scene using relief textures include modeling surfaces in a scene with one or more relief textures. Each relief texture is projected onto its basis plane based on a desired viewpoint to produce a pre-warped image. Each pre-warped image is projected onto one or more polygons used to model the scene. Because the steps of texture mapping and pre-warping are separated, solving for visibility during the pre-warping is facilitated by using one-dimensional pre-warping equations
