我這個人記性不好，學過的東西老是愛忘，學得越多忘得越快，腦子和我可憐的硬盤一樣容量比較小，所以我發現我不得不把有些東西記錄下來。其實學一樣東西關鍵在于多學多用，有道是書讀百遍其意自現，對于我這種比較笨又沒天賦的人來說可謂金玉良言了。
以上算前言吧，下邊才是正文。

Ogre這個引擎的效率不知道實際應用起來如何，但是聽說結構倒是比較好的。選擇它來學習主要是因為它開源，而且是C++和Dx寫的，關鍵還有資料比較多，國內研究的也比較多，也有一些教程，不過Ogre不斷推出新版本，許多教程都有點過期了。要了解最新的使用方法還得看官方的教程。我也是直接看官方的教程，但是英文一般，每次打開大片英文頁面看著的確比較迷糊，所以我打算把里面一些重要的關鍵部分節選出來以備參考，有時候可以快速的重溫，比如這篇要介紹的如何配置Ogre，需要記嗎？程序員記不了那么多啦，用的時候再查。當然Ogre也在持續更新，如果我個人還在持續學習使用Ogre，那么我也會持續更新這些教程的，如果你是Ogre的使用者記得來我的Blog：http://www.shnenglu.com/singohgod?看看吧，希望能對大家有點幫助。

首先安裝SDK，可以編譯里面帶的示例看看一些效果展示。編譯源碼就得下載源碼吧，記得還要下一個Dependencies，解壓到源碼目錄就可以了，編譯應該能通過的，我這里沒有遇到問題。

不要被繁多的目錄和文件嚇著了，其實運行Ogre程序只需要下列庫和文件：
OGRE Libraries & Files

• OGRE libraries (OgreMain[_d].dll, OgrePlatform[_d].dll or libOgreMain.so, libOgrePlatform.so for linux).
• plugins.cfg - Text file specifying the rendering libraries available to Ogre (ie DX9, OpenGL).
• All the plugin libraries listed in plugins.cfg (you can remove items from plugins.cfg if you don't wish to use them).
• resources.cfg - If using the ExampleApplication, a text file specifing paths to materials, textures, models, etc.
• OgreCore.zip - Ensure resources.cfg has the proper path to this file if you plan to use the OGRE debug panel or profiler.
• Other Resources used in your program (*.zip; *.png; *.particle; *.mesh; ...).

還需要其他的第三方庫：
These are required:

• Zlib: zlib1.dll; libz.so (debian: zlib1g, zlib1g-dev)
• DevIL: devil.dll, ilu.dll, ilut.dll; libIL.so, libILU.so (debian: libdevil1, libdevil-dev)

These are optional:

• CEGUI: OgreGUIRenderer[_d].dll, CEGUIBase[_d].dll, CEGUITaharezLook[_d].dll, CEGUIWindowsLook[_d].dll, xerces-c_2_5_0.dll
• CEGUI: libCEGUIBase.so, libCEGUIOgreRenderer.so, libxerces-c.so (debian: libcegui-mk2-0, libcegui-mk2-dev, libxerces26, libxerces26-dev)
• Cg: cg.dll; libCg.so (debian: nvidia-cg-toolkit)
• OpenEXR: openexr.dll??; (debian: libopenexr-dev libopenexr2 )
• ReferenceApp: ReferenceAppLayer.dll

不同的編譯器還需要有：
Extras for Microsoft Visual C++ 6 (SP3+)

• stlport_vc6[_stldebug]46.dll
• msvcp60[D].dll
• msvcrt[D].dll

Extras for Microsoft Visual C++.Net 2002

• stlport_vc7[_stldebug]46.dll
• msvcp70[d].dll
• msvcr70[d].dll

Extras for Microsoft Visual C++.Net 2003

• msvcp71[d].dll
• msvcr71[d].dll

Extras for Mingw + STLPort

• libstlport[stlg].5.0.dll
• mingwm10.dll

設置環境變量：
If you downloaded and installed the precompiled OGRE SDK, you should already have an environment variable called 'OGRE_HOME' registered already, pointing at the folder where you installed. If it isn't there you probably installed under a different user, so define OGRE_HOME manually

If you downloaded the source distribution, you should register a new environment variable OGRE_SRC pointing at the 'ogrenew' folder from the OGRE source

Ogre源碼項目的目錄結構：
work_dir
??? include
?????? *.h
??? src
?????? *.cpp
??? scripts
?????? *.vcproj

新建項目也依據這個結構，你的項目應該有這些文件夾：'bin', 'include', 'media', 'testsolution', 'scripts', and 'src'

修改新項目的屬性：
Debugging?: Working Directory?????????????????????? = ..\bin\Debug
C/C++?: Preprocessor?: Preprocessor Definitions += _STLP_DEBUG (only in Debug mode, not needed for .Net 2003 and 2005)
C/C++?: Code Generation?: Use runtime library = Multithreaded Debug DLL (Multithreaded DLL in Release)
Linker?: General?: Output File??????????????????????????? = ..\bin\Debug\[appname].exe
Linker?: Input?: Additional Dependencies??????????????? += OgreMain_d.lib (OgreMain.lib in Release)

如果你是安裝SDK:

C/C++?: General?: Additional Include Directories 	 = ..\include;$(OGRE_HOME)\include;$(OGRE_HOME)\samples\include
Linker?: General?: Additional Library Directories         = $(OGRE_HOME)\lib

如果你是編譯源碼:

C/C++?: General?: Additional Include Directories 	 = ..\include;$(OGRE_SRC)\OgreMain\include;$(OGRE_SRC)\Samples\Common\Include
Linker?: General?: Additional Library Directories         = $(OGRE_SRC)\OgreMain\Lib\Debug

這些設置好以后你就可以新建一個SampleApp.cpp文件，然后拷貝如下代碼：

#include?"ExampleApplication.h"

//?Declare?a?subclass?of?the?ExampleFrameListener?class
class?MyListener?:?public?ExampleFrameListener
{
public:
????MyListener(RenderWindow*?win,?Camera*?cam)?:?ExampleFrameListener(win,?cam)
????{
????}

????bool?frameStarted(const?FrameEvent&?evt)
????{
????????return?ExampleFrameListener::frameStarted(evt);????????
????}

????bool?frameEnded(const?FrameEvent&?evt)
????{
????????return?ExampleFrameListener::frameEnded(evt);????????
????}
};

//?Declare?a?subclass?of?the?ExampleApplication?class
class?SampleApp?:?public?ExampleApplication?
{
public:
???SampleApp()?
???{
???}

protected:
???//?Define?what?is?in?the?scene
???void?createScene(void)
???{
???????//?put?your?scene?creation?in?here
???}
??
???//?Create?new?frame?listener
???void?createFrameListener(void)
???{
???????mFrameListener?=?new?MyListener(mWindow,?mCamera);
???????mRoot->addFrameListener(mFrameListener);
???}
};

#ifdef?__cplusplus
extern?"C"?{
#endif

#if?OGRE_PLATFORM?==?OGRE_PLATFORM_WIN32?
#define?WIN32_LEAN_AND_MEAN?
#include?"windows.h"?
INT?WINAPI?WinMain(HINSTANCE?hInst,?HINSTANCE,?LPSTR?strCmdLine,?INT)?
#else?
int?main(int?argc,?char?**argv)?
#endif?
{
????//?Instantiate?our?subclass
????SampleApp?myApp;

????try?{
????????//?ExampleApplication?provides?a?go?method,?which?starts?the?rendering.
????????myApp.go();
????}
????catch?(Ogre::Exception&?e)?{
#if?OGRE_PLATFORM?==?OGRE_PLATFORM_WIN32?
????????MessageBoxA(NULL,?e.getFullDescription().c_str(),?"An?exception?has?occured!",?MB_OK?|?MB_ICONERROR?|?MB_TASKMODAL);
#else
????????std::cerr?<<?"Exception:\n";
????????std::cerr?<<?e.getFullDescription().c_str()?<<?"\n";
#endif
????????return?1;
????}

return?0;
}

#ifdef?__cplusplus
}
#endif

未完！
