Dex3d源程序，入门开发很好的参考，中间有一个3D绘图的库函，另还添加了一些3D动态转动显示等功能。-Dex3d source, started developing a good reference, the middle letter of a 3D graphics library, and the other has also added some 3D dynamic rotating display.

这是一个用来动态现实曲线波形的程序,使用directx绘图,现实蝴蝶动态动作.-direct x draw image, as far as i know, it is very special, to trafer the code, to show the dynamic waveform

基于DX8.1实现的绘图并动态渲染的基础程序，使用Graphic类封装了DD初始化函数,使用GameMain封装了游戏初始化过程-It s a procedure based on DX8.1 used for drawing a picture.it s a packing of DirectDraw s init function and also Game init function
