3dExplorer.cpp：源码内容
  1. // 3dExplorer.cpp : Defines the entry point for the application.
  2. /*********************************************
  3. 这个文件掌管整个程序的启动、运行与结束
  4. WinMain(...)为程序的入口
  5. WndProc(...)为消息处理函数，这两个函数是一般win32程序都具备的
  7. InitEngine()为运行做初始化，在该工程中，函数名以Init开头的都是完成初始化任务，
  8. 该函数只运行一次
  9. DrawGLScene()绘制场景函数，每帧调用一次
