ogre嵌入MFC教程

由于实验室项目的需要，要学习ogre嵌入MFC，在这里把我从小白到实现的过程写下来给大家分享。首先声明一下，在这里我建的是基于单文档的ogre嵌入MFC，多文档的并没有研究，后面有时间实现了再拿来分享。配置环境：VS2008+ogre1.6.5第一步：创建一个MFC SDI程序（之前并没有学过MFC，最近才开始看，这一部分也是参考网上的教程，具体哪位大侠的博客忘记了，抱歉~）1.新建项目，MFC应用程序。2.MFC应用程序向导设置如下图：3.生成的类设置如下：4.至此，一个MFC SDI程序创建完成，编译运行，可以得到一个空窗口视图。如果上一步选择基类为CFormView，那么可以进一步创建一个继承CFormView的类，可以命名为OgreControl，用来放置一些控件来和Ogre的渲染窗口进行交互。在工程名上右键->添加->类->MFC类->添加，类名OgreControl，基类为 CFormView,完成。如下图：5.6.至此第一步完成。第二步 分割窗口（暂时跳过）这一步可以暂时不用，可以在掌握Ogre和MFC之后进行进一步的学习和练习使用。本例子创建单视图文档。第三步 Ogre嵌入MFC这一步主要修改对应View的.h和.cpp文件。1.OgreMFCView.h的代码如下：

// OgreMFCView.h : COgreMFCView 类的接口//#pragma once//添加的代码#include "ogre.h"#include "OgreConfigFile.h"using namespace Ogre;class COgreMFCView : public CView{protected: // 仅从序列化创建COgreMFCView();DECLARE_DYNCREATE(COgreMFCView)// 属性public:COgreMFCDoc* GetDocument() const;// 操作public:// 重写public:virtual void OnDraw(CDC* pDC);  // 重写以绘制该视图virtual BOOL PreCreateWindow(CREATESTRUCT& cs);protected:virtual BOOL OnPreparePrinting(CPrintInfo* pInfo);virtual void OnBeginPrinting(CDC* pDC, CPrintInfo* pInfo);virtual void OnEndPrinting(CDC* pDC, CPrintInfo* pInfo);void setupResources();//添加的代码// 实现public:virtual ~COgreMFCView();#ifdef _DEBUGvirtual void AssertValid() const;virtual void Dump(CDumpContext& dc) const;#endifprotected:// 生成的消息映射函数protected:DECLARE_MESSAGE_MAP()public:afx_msg BOOL OnEraseBkgnd(CDC* pDC);afx_msg void OnLButtonDown(UINT nFlags, CPoint point);private:CPoint              m_mouseLast;Root* mRoot;RenderWindow* mWindow;SceneManager* mSceneMgr;Camera* mCamera;//添加的代码public:afx_msg void OnMouseMove(UINT nFlags, CPoint point);afx_msg void OnTimer(UINT_PTR nIDEvent);afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);afx_msg void OnDestroy();};#ifndef _DEBUG  // OgreMFCView.cpp 中的调试版本inline COgreMFCDoc* COgreMFCView::GetDocument() const{ return reinterpret_cast<COgreMFCDoc*>(m_pDocument); }#endif  

2. 修改View对应的.cpp文件

// OgreMFCView.cpp : COgreMFCView 类的实现//#include "stdafx.h"#include "OgreMFC.h"#include "OgreMFCDoc.h"#include "OgreMFCView.h"#define OGRE_DEBUG_MEMORY_MANAGER 1//#ifdef _DEBUG//#define new DEBUG_NEW//#endif// COgreMFCViewIMPLEMENT_DYNCREATE(COgreMFCView, CView)BEGIN_MESSAGE_MAP(COgreMFCView, CView)// 标准打印命令ON_COMMAND(ID_FILE_PRINT, &CView::OnFilePrint)ON_COMMAND(ID_FILE_PRINT_DIRECT,
