....or a face can be embedded onto a single point or edge. Once the correspondence is established, most of the papers use a linear or an Hermite spline interpolation between the corresponding vertices to compute the in between shapes. A specific model is introduced in some papers: Delingette et al. DWS93] use a physically based algorithm to interpolate intrinsic geometric parameters, Sun et al. SWC97] also interpolate intrinsic geometric parameters using a propagation paradigm, for restricted classes of shapes the interpolation problem is solved jointly with the correspondence problem in [KPC91, ....

....Methods for altering the topology of the surface mesh during transformation have also been presented. By introducing duplicate or degenerate surface mesh elements, Bethel and Uselton [2] can produce a transition between two surface meshes that differ topologically. Delingette et al. [3] use a simplex mesh , and perform basic mesh operations that can alter the shape topology. The interpolation was performed using a physics based deformation approach, using a method derived from a data fitting process. What makes our work different from previous work is that we emphasize both ....

....sampling can result in topological features appearing suddenly (such as an instantly appearing hole) Kent et al. addressed both the second and third points by noting that they cannot be satisfied without using both geometric and topological information during the transformation process. Only [3], 7] 8] 10] and [14] use both geometric and topological information in the morphing process. To perform the morphing, we are given two surfaces S 1 and S 2 , which we will refer to as the source shapes. For this paper, we will assume that the source shapes are triangulated polygon surfaces, ....

....St ephane Cotin, J erome Pignon ffl Creation of muscles between a part of the skull and a part of a face. ffl Interaction between muscles and the skin. In order to satisfy those constraints, we use an original representation of surfaces and volumes called simplex meshes introduced by Delingette[DWS93] This representation authorizes local changes of connexity of a mesh, which are not possible with regular structures such as those used by Waters[Wat87] TW90] Every model may be deformed under the influence of both internal or external forces, similarly to the scheme of deformable ....

....muscle actions. This constraint will ensure that the resulting face model is as close as possible to its original shape. On the other hand, when merging two skull fragments, we will smooth both models to perform a realistic surgery. A detailed description of those internal forces may be found in [DWS93] The external forces integrate the interaction between a model and its environment. The user may interact with a surface model with the virtual hand by exerting a repulsive force. Furthermore, a model may be deformed by a local potential field created at the neighborhood of some three ....
