Abstract: A method and apparatus are provided for generating vector displacement maps, often in an interactive manner. Given a set of objects to be animated or imaged, they can be each represented by one or more faces. In a subdivision process, faces might be represented by polygons through a method of repeated subdividing. In the subdivision process, relative location of polygons relative to the original face (and possibly relative orientations) are maintained, for later use by other processes. This can be done by maintaining source data for each face of a subdivided surface, where source data indicates an original location on the original object that corresponds to that face and the polygons resulting from the subdividing. The source data can be a link, path, index or label for each face of the subdivision surface, where the source data indicates an original location on the original object that corresponds to that face.
