Abstract

Given a triangular skin mesh $\mathcal M(B)$ constructed by a set of spheres B={b1, b2, ...}, we modify some selected spheres in B and generate a deformation process to a new skin surface mesh $\mathcal M(B')$. All new skin surface meshes during the deformation are constructed by moving original surface points in $\mathcal M(B)$, refining bad quality triangles and contracting short edges. Thus, the algorithm guarantees triangle quality and surface coordinate correspondence during the deformation process.
