Abstract: A method comprises encoding information in a texture map, and enhancing texturing utilizing the information, where the information identifies at least one region in at least one texture. Additionally, a texture data structure is embodied on a non-transitory computer readable medium and comprises a texture map with encoded information that identifies at least one region in at least one texture. In addition, an apparatus comprises a processor for encoding information in a texture map to enhance texturing, where the information identifies at least one region in at least one texture.

Abstract: A system, method, and computer program product are provided for carrying out texture retrieval operations. In use, it is determined whether at least one texture retrieval operation is to be performed in a predetermined mode. Based on such determination, the texture retrieval operation is performed utilizing predetermined derivatives.

Abstract: Discontinuities along texture mapped seams of three-dimensional models may be reduced by creating and sampling texture data outside of chart boundaries. When a texel center is not within a chart boundary (a group of connected triangles in texture space) a phantom face is generated that includes the texel center. Phantom texture coordinates are created for each texel center that is covered by the phantom face. The phantom texture coordinates are used to read a texture sample from another chart in texture space that is adjacent to the chart boundary in model space, producing a smooth transition across the seam.
