Morphological modeling and deformation of 3D objects

This paper decribes a new set of techniques based upon laws of object composition for the modeling and animation of deformable objects. They presemt some similarities with logical or morphological operations. This method is unique because the volume of the merged object is held constant with respect ti its constituents. Composition from two pbjects is allowed for general shapes which may have very different topologies. These techniques are applied towards shapes which are approximated by a poluhedral description. When integrated into a modeler, they can be used as modeling tools, animation tools, deformation tools or even morphing tools depending on how they are handled. One of the advantages of these tools is that the user may easily deduce the procedure to follows in order to obtain a given result.
