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

1. A mesh-based pre-warped image generator comprising computer-executable instructions embodied in a computer-readable medium for performing steps comprising:(a) computing pixel row and column values in a pre-warped image for all pixels in a relief texture utilizing first and second one-dimensional pre-warping equations; (b) storing the computed pixel row and column values and pixel color values in an intermediate array of pixels; (c) extracting a first pixel from the intermediate array of pixel; (d) rasterizing a polygon in the pre-warped image based on row, column, and color values stored for the first pixel in the intermediate array of pixels, and row, column, and color values stored in the intermediate image for pixels near the first pixel; (e) determining a location for an epipole for the relief texture based on a desired viewpoint; (f) dividing the relief texture into no more than four regions based on the location of the epipole; and (g) dividing each region into at least one row and at least one column, wherein extracting a pixel from the relief texture includes extracting pixels in an occlusion-compatible order along each row or column in each region.
