如何在vc++6.0里面使用openGl？你既可以建立Win32项目使用API，也可以建立MFC工程（一般不用MFC框架直接用API）我给你一个例子吧，建立Win32空项目，添加一个cpp文件，编译执行就行了（这是一个经典的opengl框架了）代码如下：#pragma comment(lib,"opengl32.lib")#pragma comment(lib,"glu32.lib")#pragma comment(lib,"glaux.lib")#include <windows.h>#include <gl/gl.h>#include <gl/glu.h>#include <gl/glaux.h>HDC hDC=NULL;HGLRC hRC=NULL;HWND hWnd=NULL;HINSTANCE hInstance;BOOL keys[256];BOOL active=TRUE;BOOL fullscreen=TRUE;GLfloat rtri;GLfloat rquad;LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);GLvoid ResizeGLScene(GLsizei width,GLsizei height){if(height==0)height=1;glViewport(0,0,width,height);glMatrixMode(GL_PROJECTION);glLoadIdentity();gluPerspective(45.0f,(GLfloat)width/(GLfloat)height,0.1f,100.0f);glMatrixMode(GL_MODELVIEW);glLoadIdentity();}int InitGL(GLvoid){glShadeModel(GL_SMOOTH);glClearColor(0.0f,0.0f,0.0f,0.5f);glClearDepth(1.0f);glEnable(GL_DEPTH_TEST);glDepthFunc(GL_LEQUAL);glHint(GL_PERSPECTIVE_CORRECTION_HINT,GL_NICEST);
