Abstract
We propose a shape-preserving progressive coding scheme for 3D models, focusing on the visual quality of 3D meshes at low resolutions. In order to obtain good reconstruction quality of 3D meshes, we improve a mesh simplification method based on the quadric error metric (QEM) by assigning different weighting factors according to topological constraints. We also develop an efficient geometric prediction algorithm that exploits neighboring information in the 3D mesh model to achieve high compression ratios
