Abstract

We propose a mesh simplification scheme that can reduce the number of meshes to the requested number while uniform and high-quality base meshes for subdivision surfaces. In this paper, a modified QEM (Quadric Error Metrics) scheme is proposed to obtain high-quality subdivision surfaces on which sharp features exist. To meet the requirements for surface quality and precise feature expressions, we combined mesh distortion check and feature preservation with the QEM scheme. We demonstrated our algorithm using some models including complex shapes, and the demonstrations showed the effectiveness of the proposed method.
