Only the geometries in deforming area may be deformed according to editing operations 只有变形区域中的网格点会跟随编辑工具发生位移。

The proposed method has the following properties : area control : users can specify the deforming area of the given mesh with a closed path on the surface to define the influence region of the deformation 基于几何基元的网格编辑技术有如下几个特点:变形区域可控:用户可以用变形物体面上的一条闭合曲线来定义变形区域。
