实验三 图形交互技术

实验目的：

1、通过本次实验，掌握图形输入和交互技术的方法。

2、掌握部分图形交互技术的实现方法。

3、进一步熟练编程语言环境中图形绘制技术。



实验内容：

（必做）1、综合使用鼠标、菜单、橡皮条等交互技术实现直线、圆和矩形等基本图形的绘制。

（选做）2、使用2D变换原理，绘制一个2D图形，然后用键盘或鼠标控制使它能进行适当的2D变换。

-three experimental interactive graphics technology experiment : one, through the experiments. master graphics and interactive techniques. 2, master of graphic interactive technology are realized. 3, further skilled programming language environment graphics rendering technology. Experiment : (regimen) a comprehensive use of the mouse, menu, rubber, and other interactive technology to achieve straight lines, round and rectangular basic graphics rendering. (Election so) 2, the use of 2D transform theory, drawing a 2D graphics, then use the keyboard or mouse control so that it can take appropriate 2 D transform.
