“虚拟地景生成系统”是基于Windows2000系统和Visual C++ 6.0平台，利用基本OpenGL函数编程技术开发的三维可视化成果。它通过简单的DEM（数字高程模型）数据，建立格网模型、再根据光照强度、高程值及有关数据建立数学模型，生成晕渲，再将它投影到平面上，达到模拟现实地貌起伏的效果。 本系统采用XP风格界面，清新自然。它具有透射/正射投影切换、漫游、缩放功能。支持分层晕渲、比高设定、平移、旋转、翻滚、视野调节、雾化、纹理贴图(显示/隐藏)等诸多功能，单幅、1MB大小的DEM数据生成速度为秒级，浏览时无停顿。-"to the virtual scene generation system" is based on Windows 2000 and Visual C 6.0 platform, using the basic function of OpenGL programming technology developed by 3D visualization results. Through simple DEM (Digital Elevation Model) data, establish grid model, in accordance with light intensity, elevation data and the value of a mathematical model, generate Hillshading, then it projection plane to achieve realistic simulation of the effect of undulating topography. The system uses XP style interface as well. It has transmission/switching are overhead projectors, roaming, zoom function. Support for layered Hillshading, compete against the creation, translation, rotation, rolling and vision adjustment, atomization,

opengl 写的模仿雨落下的效果，采用mfc-opengl written to imitate the effect of falling rain, using mfc

opengl双缓存动画,很有意思-opengl-cache animation, very interesting

是基于vc++6.0用opengl创建的三维场景，房间有各种特是效，雾化等，还有转动的风车，还有永动轮，因为整个主题是环保绿色，所以整个场景围绕展开

在vc的环境下关于mfc的opengl的窗口设置的简单例子,程序很简单,对opengl的初学者应该很有用.-in vc environment on the opengl mfc the window set up a simple example, the procedures are simple, right opengl beginners should be very useful.

一个互动机械臂的OpenGL code,Visual C++. s键转动第一个关节，e键转动第二个关节，w键转动第三个关节-an interactive manipulator OpenGL code, Visual C. Key Moment"s first joint, e Key Moment of the second joints, w Key Moment of the third joints

OPENGL的Text显示类. win32平台.-OPENGL display the Text category. Win32 platform.

利用OpenGL编写的烟花屏幕保护，烟花升空时还有烟花燃放的声音和鞭炮声，程序里利用FMOD库实现了播放MP3等声音文件的功能。屏幕保护程序的关键是对以下两个入口函数的编写：1、屏幕保护处理程序入口函数LRESULT WINAPI ScreenSaverProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)2、屏幕保护设置对话框BOOL WINAPI ScreenSaverConfigureDialog(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
