PROBLEM TO BE SOLVED: To provide a texture mapping device or the like for reducing the generation of the joint of the boundary of a texture, and for expressing the anisotropic texture of texture raw materials. SOLUTION: Based on the shape information of a certain region on a model surface and a texture corresponding to the region, a vector calculating means 101 calculates a plurality of projection coordinate system vectors at the time of projecting the texture to the region on the model surface. An bearing calculating means 102 calculates a point of view and the bearing of a light source corresponding to the model surface in the region from a plurality of projection coordinate system vectors and a normal corresponding to the model plane in the region. Mapping means 103 and 104 changes the texture, and maps it to the model plane corresponding to the region based on the point of view and the bearing of the light source. COPYRIGHT: (C)2006,JPO&NCIPI
