摘要:An approach to construct a C2-continuous surface for a mesh of arbitrary topology is presented in this talk. The construction process is subdivision surface based, with modification performed on extra-ordinary patches to ensure C2-continuity of the resulting surface. Implementation is easy because modification is patch-based. The resulting surface has an explicit expression of the form WMG for each extra-ordinary patch where W is a

parameter vector, M is aconstant matrix and G is the patch-wise control point vector. Therefore, computing derivatives, normals and curvatures for points in the domain of the given mesh is very easy and, consequently, the resulting surface is suitable for operations such as shape analysis, shape optimization, surface energy minimization, etc.
