不是用递归，改用贴片法。也是很基本的离散方法

用OpenGL写的地形渲染程序，适合大地形渲染，值得一看-with OpenGL written procedures exaggerated topography suitable for large Terrain Rendering, an eye-catcher

图像的获取一是bmp图像文件，二是来自剪贴板。本代码在MFC中调用OpenGL库函数来实现二维图像的三维显示，图像的宽度、高度和象素的亮度分别为三维空间的x,z,y坐标。程序主要有初始化、绘图、资源释放和操作部分，这些功能在OGL_MFCView.cpp文件中实现。OpenGL库的初始化在该文件中的OnCreate，InitScene和DrawScene函数中实现，主要初始化OpenGL运行时的环境变量，三维物体的光照，材质等

织物模拟,使用弹簧模型,很值得研究- The fabric simulation, uses the spring model, is worth studying very much

have included this Multiple Document Interface example here because any game development requires a good editor for constructing the world or models. The editor should provide multiple views of the scene and therefore the most intuitive method is to use multiple windows that allow perspective and orthographic views. In my search of the internet I was unable to find any example code that showed how to program an OpenGL Multiple Document Interface application using just straight Win32 programming with no MFC so I decided to program it myself. This MDI example only shows the same scene in each child window but should be easily understandable and modifiable by anyone familiar with programming a standard MDI application using the Win32 API. I will follow up this example with a more complete editor example.
