指定计算机图形编程的一组函数，即三维图形核心系统（GKS-3D）。GKS-3D是一个基本的图形系统，用于在图形输出设备上生成计算机生成的三维图片的应用程序。它通过提供图形输入和图片分割的基本功能，支持操作员输入和交互。它允许存储和动态修改图片。本标准与ISO 8805:1988相同，并根据ISO 8805:1988复制。

Specifies a set of functions for computer graphics programming, the Graphical Kernel System for three dimensions (GKS-3D). GKS-3D is a basic graphics system for applications that produce computer-generated three-dimensional pictures on graphics output devices. It supports operator input and interaction by supplying basic functions for graphical input and picture segmentation. It allows storage and dynamic modification of pictures. It is identical with and has been reproduced from ISO 8805:1988.
