摘要
本文应用了面表、环表、顶点表表链数据结构描述了三维空间立体图形，讨论了二维屏幕坐标转换立体空间坐标的算法及其关键技术，解决了在三维背景图上任意交互剪裁的三维图视显示技术。并在ＳＵＮ工作站上以图形用户界面（ｍｏｔｉｆ）软件为平台。
The paper applies a table data structure of suface table, ring table, vertex table to describe 3 D graph, discusses an algorithm and key technology of transferring 2 D screen coordinates to 3 D coordinates, and solves any interactive cutting display technology of 3 D graphical vision. The program has been executed by applying graphical user interface on SUN workstation.
