摘　　要：将复杂产品的形态根据造型特征简化为简单的网格模型,基于C-C曲面网格细分原理,提出了在产品造型设计中首先制作出产品的简单网格模型,由用户对网格顶点进行多次编辑修改后再进行网格细分,从而获得产品定制造型方案的方法。该方法基于网格细分,执行速度快,运算量小,在应用的过程中可使用户深度体验定制设计过程,设计师只需要制作出产品的初始形态的简单网格,由用户便捷地修改顶点位置,无需进行大量的曲面编辑操作,便可迅速获得多种产品造型方案,从而提高产品造型设计效率。A method for product design based on Catmull-Clark （ C-C ） subdivision technology is proposed. Firstly, the designer provides a basic simple mesh model of the product with the vertex editable. Then, the vertex＇ s position can be modified by not on- ly the designer, but also the users. Finally, the mesh is subdivided and a new product solution is obtained. This method based on subdivision technology, has more faster execution speed and small amount of computation. What the designer need do is only to create a simple product mesh, then the rest work was done all by users. This method is easy to conduct, and can obtain customized product form solutions, which is able to make the design process more efficient.
