Mesh simplification is an efficient method to reduce the time of computer handling complicated models. It requires the algorithm with less processing time and space complexity, while the quality of simplification and the consistency of the simplified triangles are quite well. This paper presents a mesh simplification algorithm of three-dimensional models defined by triangle-mesh. In this algorithm, the gradient of the curvature of surface is used as the simplification condition, the manner of simplification is edge collapse and the error metrics is the distance between vertex before simplifying and the related surface after simplifying. Experiment results indicate that this algorithm can be applied to any topological mesh and has the advantages of speediness and efficiency.
