通过VC++进行一个有关OPENGL的编程（请打出此程序）

程序要求如下

程序运用C++代码完成

程序能够达到运用鼠标或者键盘进行对图像的缩放和移动操作

3D图像形状不限 不需渲染等高级操作

请说明程序代码和操作方法

这样的opengl例子很多，代码量都比较大，如果你要的话，告诉我你的邮箱，我发给你几个。现在我把其中比较简单的一个类定义及说明和里面主要的函数贴在下面：
放大/缩小/旋转效果是在显示时（响应WM_PAINT消息）实现的，操作仅仅是改变了显示的参数，这些参数包括：m_ScaleX、m_ScaleY、m_ScaleZ用来处理放大/缩小；m_xRotate、m_yRotate用来处理旋转。类定义如下：
class CDialogGLDlg : public CDialog
{
// Construction
public:
CDialogGLDlg(CWnd* pParent = NULL); // standard constructor

BOOL SetWindowPixelFormat(HDC hDC); // 设置当前窗口的属性适应opengl显示
BOOL CreateViewGLContext(HDC hDC); // 将opengl与当前窗口绑定
void BuildList(); // 将显示的图像信息传递到opengl系统中

HGLRC m_hGLContext;
int m_GLPixelIndex;

void RenderScene(); // 将操作时设置的显示参数传递到opengl系统中并显示图像
float m_ScaleX;
float m_ScaleY;
float m_ScaleZ;
GLdouble m_xRotate;
GLdouble m_yRotate;
CPoint m_LeftDownPos; // 处理鼠标拖动操作时用来设置旋转参数
BOOL m_LeftButtonDown; // 用来判断鼠标是否在拖动

// Dialog Data
enum { IDD = IDD_DIALOGGL_DIALOG };
protected:
virtual void DoDataExchange(CDataExchange* pDX);

afx_msg void OnLButtonDown(UINT nFlags, CPoint point);
afx_msg void OnLButtonUp(UINT nFlags, CPoint point);
afx_msg void OnMouseMove(UINT nFlags, CPoint point);//处理鼠标左键拖动时旋转操作
afx_msg void OnTimer(UINT nIDEvent);// 定时改变坐标系，并刷新屏幕达到旋转的效果
afx_msg void OnPopupRotate();// 处理右键弹出菜单中的旋转命令
afx_msg void OnPopupSizeDecrease();//处理右键弹出菜单中的缩小命令
afx_msg void OnPopupSizeIncrease();//处理右键弹出菜单中的放大命令

你说的图像是表面贴图的一个立体模型还是一张二维图片？从描述上来看感觉像是二维图片，你可以参考甚至直接使用opengl关于纹理贴图的示例，简单来说，就是建立两个共长边的等边三角形，拼起来是一个矩形，然后在初始化程序时引入图像文件作为纹理，给俩三角形共6个顶点进行纹理映射坐标的赋值，定义一个观测用相机数据，视效果有可能需要定义一个光源，然后在程序的循环渲染函数中进行纹理贴图渲染操作，主函数则无限循环处理鼠标或键盘输入，无论是缩放还是移动，只是简单的变换一下相机坐标信息即可达到
