Abstract:
1. A computer-readable medium embodied with a computer program for providing a graphic image utilizing view-dependent texture data, said computer program comprising: a graphic data code segment for providing data representing a graphic image; and a texture data code segment in operational association with said graphic data code segment, said texture data code segment including view-dependent texture data formed by steps of: deriving a three-dimensional polygon mesh from data obtained from at least one of a plurality of two-dimensional source images; forming a single master texture coordinate space by mapping said polygon mesh into an optimized 2-D space; forming at least one two-dimensional master image by remapping each of said plurality of source images into said single master texture coordinate space, wherein said master texture coordinate space comprises a single set of texture coordinates for all source images such that the single master texture coordinate space is utilized for all source images without requiring a new map, wherein each source image corresponds to a different viewing or camera position for a graphic image for display; locating and identifying any occluded pixels in the master image and, if occluded pixels are found, replacing occluded pixels with a combination of one or more non-occluded pixels from other source images; and assigning texture coordinate data to three-dimensional coordinates on said mesh by mapping the three-dimensional coordinates to two-dimensional coordinates using said master texture coordinate space, thereby providing common texture data for each master image.
