交互式图形系统IGS功能及实现

Function and Realization of Interactive Graphics System

在VAX GKS基础上开发出二维交互式图形系统IGS(Interactive Graphics System).IGS具有很强的图形输入、输出、存贮、编辑、计算、输出等功能;它成功地引入了GKS的坐标系、图、节等重要概念;IGS还有图处理设计功能.

This paper presents two dimensional interactive graphics system (IGS), which is developed taking VAX GKS as graphics system kernel system. It can be widely used in many areas such as architecture . mechanical design , map processing , etc. This paper illustrates the designing ideas , functions, methods of realization , characteristics of IGS system. Some examples of application are also given.
