一个基于抽象类层次和扩展 CSG 结构的图形建模方法

An Abstract Hierarchical Class and Extended CSG Structure Based Method for Graphical Modeling

介绍了一个基于抽象类层次和扩展ＣＳＧ结构的面向对象图形建模方法首先讨论了利用面向对象技术建模的特点，然后从两个抽象类层次描述了建模系统的结构，在分析传统的实体造型技术ＣＳＧ方法基础上。

An abstract hierarchical class and extended CSG structure based method for graphical modeling is introduced in this paper.After discussing the features of object-oriented graphical modeling,a new system based on two abstract hierarchical classes is given.On the basis of describing the traditional solid modeling technique CSG,the concept and its applications of extended CSG structure is presented in order to meet the requirements of object-oriented graphical modeling.
