The basic application of the csg on building - modeling is discussed , and one volume - cell ( voxel ) growth method is put forward 介绍了csg在建筑建模中的基本应用,提出了一种基于体素生长的建筑物csg建模方法。
The main work stated in this thesis focuses in the following aspects . 1 . the improvement on csg modeling technique applied to building - modeling 本文所做的研究工作集中在四个方面: 1 .建筑物csg建模方法的改进。

In this thesis , at first every geometry model of vmt ' s component is designed by the principles of object oriented programming ( oop ) , and then the vmt is constituted through csg 本文运用面向对象建模技术建立了虚拟机床各部件的三维模型,然后以构造的实体几何法( csg )构造出整个虚拟机床几何模型。
