Detailed Description

Adaptor to Ogre3d.

Provides the interface to load, initialize the rendering engine.

Member Enumeration Documentation

enum RenderPathType

The type of rendering path used by the rendering engine.

Enumerator
NONE	No rendering is done.
VERTEX	Most basic rendering, with least fidelity.
FORWARD	Utilizes the RTT shader system.
DEFERRED	Utilizes deferred rendering. Best fidelity.
RENDER_PATH_COUNT	Count of the rendering path enums.

Member Function Documentation

void AddResourcePath

(

const std::string &

_uri

)

Add a new path for Ogre to search for resources.

Parameters

[in]

_uri

URI of the path. The uri should be of the form file:// or model://

ScenePtr CreateScene	(	const std::string &	_name,
		bool	_enableVisualizations,
		bool	_isServer = false
	)

Create a scene.

Parameters

[in]	_name	The name of the scene.
[in]	_enableVisualizations	True enables visualization elements such as laser lines.

void Fini

(

)

Tears down the rendering engine.

RenderPathType GetRenderPathType

(

)

const

Get the type of rendering path to use.

This is automatically determined based on the computers capabilities

Returns

The RenderPathType

ScenePtr GetScene

(

const std::string &

_name = ""

)

Get a scene by name.

Parameters

[in]

_name

Name of the scene to retreive.

Returns

A pointer to the Scene, or NULL if the scene doesn't exist.

ScenePtr GetScene

(

unsigned int

_index

)

Get a scene by index.

The index should be between 0 and GetSceneCount().

Parameters

[in]

_index

The index of the scene.

Returns

A pointer to a Scene, or NULL if the index was invalid.

unsigned int GetSceneCount

(

)

const

Get the number of scenes.

Returns

The number of scenes created by the RenderEngine.

Deprecated:

See SceneCount()

WindowManagerPtr GetWindowManager

(

)

const

Get a pointer to the window manager.

Returns

Pointer to the window manager.

void Init

(

)

Initialize Ogre. Load must happen before Init.

static RenderEngine * Instance ( )

inlinestaticinherited

Get an instance of the singleton.

void Load

(

)

Load the parameters for Ogre. Load must happen before Init.

void RemoveScene

(

const std::string &

_name

)

Remove a scene.

Parameters

[in]

_name

The name of the scene to remove.

Ogre::Root* Root

(

)

const

Get a pointer to the Ogre root object.

Returns

Pointer to the Ogre root object.

unsigned int SceneCount

(

)

const

Get the number of scenes.

Returns

The number of scenes created by the RenderEngine.
