英语翻译在计算机绘图的过程中,二维图形的绘制是绘制许多图形的基础,研究计算机图形的生成必须从研究二维图形开始.计算机绘制图形时,无论图形多么复杂,都是利用一些相应图形基元经过图形变换组成的.在计算机绘图中,经常用到图形变换,图形变换是指图形信息经过几何变换后产生新的图形.本文主要介绍二维图形的一些基本变换规则及其应用.图形的变换牵扯到平移变换.比例变换,还有旋转变换,本文针对简单的二维图形进行变换,比如三角形,矩形和圆形,还有随机连线的绘制,并包括了颜色的添加,动画的设计,有这些简单的设计便组成了强大的应用效果.

To study the generation of computer-aided drawing, we should start from two-dimentional plotting which is the foundation of many drawings in the process of computer-aided drawing. However complex the graphics are, they are formed with relevant graph primitives transforming. Graphic transforming is frequently used in the computer-aided drawing. Graphic transforming is to generate the graphs by geometric transformation. In this article, the basic rules and their applications will be introduced. Translation transformation scaling transformation, rotation transformation are involved in graphic transforming. This article aiming at some simple transformation of two-dimentional plotting. It includes the drawing of triangle, rectangle, circle and random ligature. Coloring and animation design are also added to creat powerfull-effects of applications with these simple designs.
