Edge collapse based on discrete crvature.

Lü Sheng-min, YANG Xun-nian, WANG Guo-zhao(Institute of Computer Graphics and Image Processing, Zhejiang University, Hangzhou 310027, China)  
Most of the simplification algorithms use a distance metric as simplification criteria. The distance metric is good to measure geometric errors between original mesh and the result, but it is not good for preserving the shape of the original model. This paper proposes a mesh simplification algorithm based on vertex's curvature, which use edge collapse method to reduce the density of low-curvature region of meshes. As the curvature is useful to enhance the shape description, the shape of the model can be preserved well after our simplification process.
