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

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.
