1、《计算机图形学》实验报告一、实验要求1、练习使用GDI函数绘出基本几何元素，如点、线、矩形、圆、椭圆、多边形、圆弧等、并能够用颜色填充2、练习使用GDI函数显示图像3、使用opengl函数写一个控制台程序，要求输出一些简单的二维图形：如线（实线、虚线）、四边形、多边形、圆、六面体、球、圆锥、茶壶等。二、实验目的1.掌握Window图形编程的基本方法；2.学会使用基本绘图函数和WindowGDI对象；三、实验环境Windows系统,vs2017四、实验内容与步骤1、练习使用GDI函数绘出基本几何元素，如点、线、矩形、圆、椭圆、多边形、圆弧等、并能够用颜色填充//线pDC->MoveTo(100
