Aim To study a mesh simplification methed for the three-dimeusional mesh model.Methods According to distribution of feature points,the face was divided into several parts,and named critical feature regional or non-critical feature regional.It adjusted different areas through giving different curvature values,this algorithm used edge collapse method to reduce the density of meshes.Results As the curvature was useful to enhance the shape description,the details of facial feature were kept while other areas were simplified in a large extent when this method was applied.Conclusion Mesh simplification method is based on features region partion for the threedimensional mesh model.The cemplexity of these models were reduced.
