集中介绍了HDC,CDC,CClientDC,CPaintDC,CWindowDC的使用方法和区别，绘图显示效果，区分窗口客户区。(Focus on the HDC, CDC, CClientDC, CPaintDC, CWindowDC to use and distinction, graphics effects, to distinguish the window client area.)

中点画圆与中点画直线 二维图形变换 多边形填充 计算机图形学实验(The midpoint Circle draws line in two-dimensional graphics transform polygon fill, computer graphics experiments)

本程序实现了计算机图形学的一些重要算法（画直线，画圆，画椭圆，区域填充，图形裁剪，齿轮生成，三次样条曲线等等），源码和可执行程序均打包于文件中(this program is implemented some important algorithm of computer graphics such as drawing lines,drawing circles,drawing ellipse,area filling,Graphics clipping，gear wheel generation ，three times spline curve and so on），source code and executable files are all included in the compressed file。 )

这是一个简单的画圆功能，主要让用户学会如何利用Windows提供的画图工具，用户单击鼠标右键则会弹出对话框选择线宽，在菜单上也设计了圆的颜色选择菜单。(This is a simple function of the Circle. mainly for users to learn how to use Windows for the drawing tools, Users right-click pop-up dialog box will be chosen linewidth, the menu also designed a circular color choice menu.)

VC动态绘制图像 真的 很好(VC dynamically drawn image very good)

计算机图形学_实体构造实验，典型的实体空间旋转(Computer graphics _ entity structure experiments, the typical physical space rotation)

DDA直线绘制程序实现，可以是任意的直线。(DDA line drawing program, a straight line can be arbitrary.)

实现贝塞尔曲线的编程，即人为指定N个点，程序自动生成这N个点的贝塞尔曲线。(Programming Bezier curve, namely human specified N points, the program automatically generates N points Bezier curve.)

说明：  用VC++编写，MFC文档框架，是一个简易的画图小程序，在文档界面上画图(With VC++ Prepared, MFC framework document is a simple drawing of small procedures, the document interface drawing)
