• Because 3d modeling must express accurately the shape of product , it is complicated compared to 2d drawing and requires designer to know computer more
  由于三维模型需完全、精确反映产品的几何拓扑关系，因此，三维造型较二维设计繁琐、复杂，对设计人员计算机应用能力要求高。
• Skeleton is an efficient representation of object shapes since it reflects the topological structure of the original shape in a simpler manner , so that it can offer an effective method to control its topological change
  与距离变换密切相关的概念是骨架化。骨架是形状表示的一种有效形式，以更为简单的形式反映原形状的几何拓扑结构，进而可为控制其拓扑变化提供有效的手段。
