A Topology Preserved Mesh Simplification Algorithm

These large-volume mesh models face challenge in rendering, storing, and transmission for the further geometrical reconstruction. This paper presents a feature extraction based mesh simplification method to get a topology preserved simple mesh model. Sequence of mesh simplification is controlled on the basis of geometrical feature sensitivity, which results in coarse mesh in the flat region and fine mesh around the areas of crease and corner. This algorithm helps to decrease the size of the simplified file by largely simplifying flat area and helps to preserve the geometric feature at large-scale simplification.
