基于特征的几何造型中数据结构的研究

A Study on the Data Structure of Feature Based Modeling

提出一种在几何特征建模中用于定义特征的交互技术，以相应的数据结构定义基本的几何特征，几何模型的建立就可通过添加特征与另一特征而实现使得图形在一组几何尺寸发生改变时能方便地重新生成几何图形。

In this paper, an interactive technique for the definition of features in geometry feature based modeling is proposed, and the basic geometric feature is defined with the corresponding data structure. Thus the modeling can be obtained through the addition of one feature to another, and a new graph can be regenerated easily when a group of geometric dimensions is changed.
