摘要
三维图形的几何变换是计算机图形设计的重要基本技术．文章主要介绍作者在三维图形系统ＧＰ３Ｄ的设计开发中，以矢量代数的方法对三维图形元素作直接旋转、平移等变换，生成复杂的组合图形（Ｏｂｊｅｃｔ），并以旋楼梯的线框图造型进行验证．
Geometrical transformation of 3-D picture is a fundamental technology of computer graphics design. In this peper it is mainly introduced that the 3-D picture transformation, such as rotation and shift, is carried out by the author using the method of vector algebra to construct compound object. And it is tested and verified by the wire frame construction of a helistais.
