Morphing of triangular meshes in shape space
International Journal of Shape Modeling , Volume 16 - Issue 1-2 p. 195- 212
We present a novel approach to morph between two isometric poses of the same non-rigid object given as triangular meshes. We model the morphs as linear interpolations in a suitable shape space S. For triangulated 3D polygons, we prove that interpolating linearly in this shape space corresponds to the most isometric morph in ℝ3. We then extend this shape space to arbitrary triangulations in 3D using a heuristic approach and show the practical use of the approach using experiments. Furthermore, we discuss a modified shape space that is useful for isometric skeleton morphing. The novelty of the presented approaches is a solution to the morphing problem that does not need to solve a minimization problem.
