Surface fairing and featuring by mean curvature motions

摘要

The aim of this paper is smoothing triangular surface meshes using a diffusion process while preserving or enhancing several important features. These features include sharp feature, detail structure, homogeneity of the mesh, interpolation of some vertices and approximation of the initial mesh. We realize these goals using a unified partial differential equation model, so that the numerical solving process of the equation is significantly simplified.
