CPoint      m_mousePoint;        //记录鼠标信息
GLfloat     m_xAngle,m_yAngle;   //控制旋转
GLfloat     m_Scale;             //用于缩放
GLfloat     m_xPos;

2.再在构造函数中初始化：

m_xAngle = 0.0f;
m_yAngle = 0.0f;
m_Scale = 1.f;
m_xPos = 0.0f;
m_yPos = 0.0f;

void CStepinGLView::OnLButtonDown(UINT nFlags, CPoint point)
{// TODO: 在此添加消息处理程序代码和/或调用默认值m_mousePoint = point;SetCapture();   //设置鼠标按下捕获CView::OnLButtonDown(nFlags, point);
}

鼠标左键释放：

void CStepinGLView::OnLButtonUp(UINT nFlags, CPoint point)
{// TODO: 在此添加消息处理程序代码和/或调用默认值m_mousePoint = point;ReleaseCapture();CView::OnLButtonUp(nFlags, point);
}

鼠标移动：

void CStepinGLView::OnMouseMove(UINT nFlags, CPoint point)
{// TODO: 在此添加消息处理程序代码和/或调用默认值if (GetCapture() == this){m_xAngle+=(point.y-m_mousePoint.y)/3.6;m_yAngle+=(point.x-m_mousePoint.x)/3.6;InvalidateRect(NULL,FALSE);//Set the mouse pointm_mousePoint = point;}CView::OnMouseMove(nFlags, point);
}

鼠标中间滑轮：

BOOL CStepinGLView::OnMouseWheel(UINT nFlags, short zDelta, CPoint pt)
{// TODO: 在此添加消息处理程序代码和/或调用默认值m_Scale += 0.1 *zDelta /120;InvalidateRect(NULL,FALSE);return CView::OnMouseWheel(nFlags, zDelta, pt);
}

void CStepinGLView::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{// TODO: 在此添加消息处理程序代码和/或调用默认值switch (nChar){case VK_UP:      m_yPos = m_yPos + 0.1f;break;case VK_DOWN:    m_yPos = m_yPos - 0.1f;break;case VK_LEFT:    m_xPos = m_xPos - 0.1f;break;case VK_RIGHT:  m_xPos = m_xPos + 0.1f;break;default:        MessageBox(L"请按 ↑ ↓ ← → 键！");break;}Invalidate(FALSE);   CView::OnKeyDown(nChar, nRepCnt, nFlags);
}

void CStepinGLView::DrawScene(void)
{//移动物体到显示区glTranslatef(0.f,0.f,-7.0f);glPolygonMode(GL_FRONT_AND_BACK,GL_FILL);//视角变换  glMatrixMode(GL_MODELVIEW);  glLoadIdentity(); gluLookAt(0.0,3.0,7.0, 0.0,0.0,0.0, 0.0,1.0,0.0);/*前三个参数是眼睛的位置，中间三个参数是物体所在的位置，后面三个参数表示向量，头顶朝上的方向*/  glEnable(GL_LIGHTING);glEnable(GL_LIGHT0);glEnable(GL_NORMALIZE);glEnable(GL_COLOR_MATERIAL);glPushMatrix();LightM();glPopMatrix();glPushMatrix();glColor3f(0.5f, 0.25f, 0.0f);glTranslatef(m_xPos,m_yPos,0.0f);glRotatef(rtri,0.0f,0.1f,0.0f);          //旋转glRotatef(m_xAngle, 1.0f,0.0f,0.0f);glRotatef(m_yAngle, 0.0f,1.0f,0.0f);glScalef(m_Scale,m_Scale,m_Scale);      //缩放glutSolidTeapot(0.5f);glPopMatrix();glPushMatrix();glRotated(-65,1.0,0.0,0.0);DrawWater();glPopMatrix();glDisable(GL_LIGHTING);glDisable(GL_COLOR_MATERIAL);}
