To preserve appearance attributes in a 3D model, a novel mesh simplification is proposed in this work based on the Quadric Error Metric (QEM). We make use of half-edge collapse method for mesh simplification and modify the QEM to solve the break between different texture coordinates. After analyzing several cases of the collapsing operation, a new formula on the cost of edge contraction is obtained to eliminate aberrances. Experimental results demonstrate that compared with other state-of-the-art techniques our algorithm can achieve satisfactory efficiency with desirable geometry and feature-preserving. © Springer-Verlag Berlin Heidelberg 2007.
