An adjustable subdivision surface modeling based on quadrilateral meshes
基于四边形网格的可调细分曲面造型方法

This paper presented an adjustable subdivision surface scheme based on quadrilateral meshes.The scheme can deal with both open topological structures and close topological structures.The scheme can produce subdivision surface of C1 continuity of limit surface.Because an adjustable parameter was introduced to the scheme,the surface modeling was flexible.Given the condition of the initial data,we can adjust and control the limit surface shape through selecting appropriate parameters.The method is effective in generating smooth surfaces.
