ABSTRACT = {In this report, a new free-form shape deformation approach is proposed.<br>We combine a skeleton-driven mesh deformation technique with discrete<br>differential coordinates in order to create natural-looking global shape <br>deformations. Given a triangle mesh, we first extract a skeletal mesh, a <br>two-sided<br>Voronoi-based approximation of the medial axis. Next the skeletal mesh <br>is modified by free-form deformations. Then a desired global shape <br>deformation is obtained by reconstructing the shape corresponding to the <br>deformed skeletal mesh. The reconstruction is based on using discrete <br>differential coordinates.<br> Our method preserves fine geometric details and original shape <br>thickness because of using discrete differential coordinates and <br>skeleton-driven deformations. We also develop a new mesh evolution <br>technique which allow us to eliminate possible global and local <br>self-intersections of the deformed mesh while preserving fine geometric <br>details. Finally, we present a multiresolution version of our approach <br>in order to simplify and accelerate the deformation process.},
