配置文件

在new一个Root对象的时候，需要传递3个参数：

Root(const String& pluginFileName = "plugins.cfg", const String& configFileName = "ogre.cfg", const String& logFileName = "Ogre.log");

1.plugins.cfg：这个配置文件，配置了需要加载那些插件，这里只列举win32格式的配置

# Defines plugins to load

# Define plugin folder

PluginFolder=.

# Define plugins

Plugin=RenderSystem_Direct3D9

Plugin=RenderSystem_GL

Plugin=Plugin_ParticleFX

Plugin=Plugin_BSPSceneManager

Plugin=Plugin_OctreeSceneManager

Plugin=Plugin_CgProgramManager

2.ogre.cfg ：在启动ogre时会弹出一个配置对话框，这个对话框就跟这个配置文件对应，一般情况下，我们会屏蔽掉对话框。但是，配置文件我们还是需要的，至少渲染管理器类型是在这个配置文件中指定的。

Render System=OpenGL Rendering Subsystem

[Direct3D9 Rendering Subsystem]

Allow NVPerfHUD=No

Anti aliasing=None

Floating-point mode=Fastest

Full Screen=No

Rendering Device=NVIDIA GeForce Go 7600

VSync=No

Video Mode=800 x 600 @ 32-bit colour

[OpenGL Rendering Subsystem]

Colour Depth=32

Display Frequency=N/A

FSAA=0

Full Screen=No

RTT Preferred Mode=FBO

VSync=No

Video Mode=1024 x 768

3.resources.cfg ：配置资源相关的路径，用于资源管理器加载资源，也可以手动加载。
