Method and apparatus for reducing the polygon count of a textured, three dimensional model of an object
First Claim
1. A method for creating a textured, three dimensional model having a reduced polygon count from a source model, said method comprising the steps of:
- applying a decimation technique to the source model to create the geometry of the textured, three dimensional model; and
creating a texture for each polygon in the geometry of the textured, three dimensional model based upon corresponding polygons in a geometry of the source model.

Abstract
The present invention describes a system and method for creating a textured, three dimensional model with a low polygon count from a source model having a high polygon count, while maintaining details of the model. The invention creates textures from the source model for polygons in the newly created model to maintain detail. In particular, a decimation technique is used to reduce the number of polygons from the source model to the resulting model. The system then renders sets of polygons, including textures, in the source model corresponding to each polygon in the resulting model. The rendered polygons are used to create textures for the resulting model.
