WebmyImage [texSize*i + j]; The mapping algorithms can be thought of as either modifying the shading algorithm based on a two-dimensional array, the map, or modifying the shading by using the map to alter the surface using three major techniques: 1. Texture mapping. 2. Bump mapping. 3. Environment mapping.
