Local modification of skin surface mesh: Towards free-form skin surface deformation

Abstract

Given a triangular skin mesh constructed by a set of spheres B={b 1, b 2, ...}, we modify some selected spheres in B and generate a deformation process to a new skin surface mesh . All new skin surface meshes during the deformation are constructed by moving original surface points in , refining bad quality triangles and contracting short edges. Thus, the algorithm guarantees triangle quality and surface coordinate correspondence during the deformation process. © 2011 Springer-Verlag.
