Abstract
A method, system and computer-readable medium for tessellating textures and mapping the resulting texture fragments onto the surface geometries of a three-dimensional model is disclosed. First, a texture is fragmented into texture fragments based on rasterization requirements. Then, the corresponding surface geometry of the three-dimensional model is fragmented so as to correspond to the texture fragments and each texture fragment is mapped to a corresponding surface geometry fragment. This process is repeated for each viewable geometric surface of the three-dimensional model that is to be textured. Thereafter, the three-dimensional model is displayed with the texture fragments mapped to the surface geometries. Prior to the mapping, the polygons, e.g., triangles, that define the surface geometries that are divided by the boundaries between texture image fragments are reconstituted as new, smaller triangles.
