開發(fā)環(huán)境 OGRE 1.72
本文需要熟悉MFC，本文并非原創(chuàng)，這里只是進行總結(jié)歸納。代碼地址：

1、在CWinApp::InitInstance中完成OGRE初始化。
初始化
1
#ifdef DEBUG
2 mRoot = new Ogre::Root("plugins_d.cfg", "OgreMFC.cfg", "OgreMFC.log");
3#else
4 mRoot = new Ogre::Root("plugins.cfg", "OgreMFC.cfg", "OgreMFC.log");
5#endif
6
7 //
8 // Setup paths to all resources
9 //
10
11 Ogre::ConfigFile cf;
12 cf.load("resources_d.cfg");
13
14 // Go through all sections & settings in the file
15 ConfigFile::SectionIterator seci = cf.getSectionIterator();
16
17 String secName, typeName, archName;
18 while (seci.hasMoreElements())
19 
{
20
secName = seci.peekNextKey();
21 ConfigFile::SettingsMultiMap *settings = seci.getNext();
22 ConfigFile::SettingsMultiMap::iterator i;
23 for (i = settings->begin(); i != settings->end(); ++i)
24
{
25 typeName = i->first;
26 archName = i->second;
27 ResourceGroupManager::getSingleton().addResourceLocation( archName, typeName, secName);
28
}
29
}
30
31 const RenderSystemList& render = mRoot->getAvailableRenderers();
32
33 RenderSystemList::const_iterator pRend = render.begin();
34
35 while (pRend != render.end())
36 {
37 Ogre::String rName = (*pRend)->getName();
38 //if (rName == "OpenGL Rendering Subsystem") //
39 if (rName == "Direct3D9 Rendering Subsystem") //Direct3D9 Rendering Subsystem
40 break;
41 pRend++;
42 }
43
44 if (pRend == render.end())
45 {
46 // Unrecognised render system
47 AfxMessageBox("Unable to locate OpenGL rendering system. Application is terminating");
48 return FALSE;
49 }
50
51 Ogre::RenderSystem *rsys = *pRend;
52 rsys->setConfigOption("Full Screen", "No");
53 rsys->setConfigOption("VSync", "Yes");
54
55 // Set the rendering system.
56 mRoot->setRenderSystem(rsys);
57
58 //
59 // Initialize the system, but don't create a render window.
60 //
61 mRoot->initialise(false);2、在View中完成OGRE所有相關(guān)創(chuàng)建操作：創(chuàng)建渲染窗口、創(chuàng)建場景管理器、創(chuàng)建攝像頭、創(chuàng)建視口、加載資源、并創(chuàng)建場景
3、view持有FrameListener的派生對象，這個對象真正執(zhí)行場景的創(chuàng)建和監(jiān)聽事件的回調(diào)，包括最關(guān)鍵的frameStarted
4、在view的paint消息中執(zhí)行幀渲染：
renderOneFrame()
5、在view中啟動定時器，比便模擬主循環(huán)操作。這個定時器讓窗口失效，從而驅(qū)動幀渲染。
6、在FrameListener對象中執(zhí)行用戶邏輯處理
