Geometric versus Volumetric 3D Models

The models subjected to 3D morphing can be described either by geometric primitives or by volumes (volumetric data sets). Each representation requires different morphing algorithms. This dichotomy parallels the separation of 2D morphing techniques into those that operate on raster images [21] [2] [6], and those that assume vector-based image representations [16]. We believe that volume-based descriptions are more appropriate for 3D morphing for the following reasons:
