Abstract
A method and system are disclosed for creating three-dimensional models in a graphics texture mapping system and are especially useful for creating three-dimensional urban models. A computer includes a graphics application program and an application programming interface. A single rectangular, composite building texture map is formed for each of a plurality of three-dimensional objects corresponding to individual buildings and have a reduced area of pixels within each composite building texture map as caused by rotating individual images. A site model clip map image contains each composite building texture map in a spatially correct position that has been expanded such that no overlap remains.
