把这三个库文件加入你的过程中：opengl32.lib glu32.lib glaux.lib 
VIEW中再包括以下头文件：
#include "gl\gl.h"
#include "gl\glu.h"
#include "gl\glaux.h"
就可以最VIEW中使用OpenGL了。请看下面的例子：int CAtlas98GLView::OnCreate(LPCREATESTRUCT lpCreateStruct) 
{
if (CScrollView::OnCreate(lpCreateStruct) == -1)
return -1;

// TODO: Add your specialized creation code here
InitPixelFormat();
InitProjection();
return 0;
}void CAtlas98GLView::InitPixelFormat()
{
HGLRC hrc;
    m_pDC = new CClientDC(this);
    ASSERT(m_pDC != NULL);
    if (!bSetupPixelFormat())
        return;
    hrc = wglCreateContext(m_pDC->GetSafeHdc());
    wglMakeCurrent(m_pDC->GetSafeHdc(), hrc);
}BOOL CAtlas98GLView::bSetupPixelFormat()
{
    static PIXELFORMATDESCRIPTOR pfd = 
{
        sizeof(PIXELFORMATDESCRIPTOR),  // size of this pfd
        1,                              // version number
        PFD_DRAW_TO_WINDOW |            // support window
          PFD_SUPPORT_OPENGL |          // support OpenGL
          PFD_DOUBLEBUFFER,             // double buffered
        PFD_TYPE_RGBA,                  // RGBA type
        24,                             // 24-bit color depth
        0, 0, 0, 0, 0, 0,               // color bits ignored
        0,                              // no alpha buffer
        0,                              // shift bit ignored
        0,                              // no accumulation buffer
        0, 0, 0, 0,                     // accum bits ignored
        32,                             // 32-bit z-buffer
        0,                              // no stencil buffer
        0,                              // no auxiliary buffer
        PFD_MAIN_PLANE,                 // main layer
        0,                              // reserved
        0, 0, 0                         // layer masks ignored
    };
    int pixelformat;    if ( (pixelformat = ChoosePixelFormat(m_pDC->GetSafeHdc(), &pfd)) == 0 )
    {
        MessageBox("ChoosePixelFormat failed");
        return FALSE;
    }    if (SetPixelFormat(m_pDC->GetSafeHdc(), pixelformat, &pfd) == FALSE)
    {
        MessageBox("SetPixelFormat failed");
        return FALSE;
    }    return TRUE;
}
void CAtlas98GLView::InitProjection()
{
GLfloat fMaxObjSize, fAspect;
GLfloat fNearPlane, fFarPlane;    GetClientRect(&m_oldRect);
if(m_oldRect.bottom == 0)
m_oldRect.bottom = 1;
    
glViewport(0,0,m_oldRect.right,m_oldRect.bottom); glClearDepth(1.0f);
    glEnable(GL_DEPTH_TEST); fAspect = (GLfloat)m_oldRect.right/m_oldRect.bottom;
fNearPlane = 0.001f;
// fFarPlane = 20.0f;
// fMaxObjSize = 20.0f;
fFarPlane = 10.0f;
fMaxObjSize = 10.0f;
m_dRadius = fNearPlane + fMaxObjSize/2.0f;    glMatrixMode(GL_PROJECTION);
    glLoadIdentity();
    gluPerspective(45.0f, fAspect, fNearPlane, fFarPlane);
    glMatrixMode(GL_MODELVIEW);
