◆ RenderEngineManager()

RenderEngineManager ( )

Constructor.

◆ ~RenderEngineManager()

~RenderEngineManager ( )

Deconstructor.

Member Function Documentation

◆ Engine()

RenderEngine* Engine	(	const std::string &	_name,
		const std::map< std::string, std::string > &	_params = `{}`,
		const std::string &	_path = `""`
	)

Get the render-engine with the given name. If the no render-engine is registered under the given name, NULL will be returned.

Parameters

[in]	_name	Name of the desired render-engine
[in]	_params	Parameters to be passed to the render engine.
[in]	_path	Another search path for rendering engine plugin.

Returns: The specified render-engine

◆ EngineAt()

RenderEngine* EngineAt	(	unsigned int	_index,
		const std::map< std::string, std::string > &	_params = `{}`,
		const std::string &	_path = `""`
	)

Get the render-engine at the given index. If no render-engine is exists at the given index, NULL will be returned.

Parameters

[in]	_index	Index of the desired render-engine
[in]	_params	Parameters to be passed to the render engine.
[in]	_path	Another search path for rendering engine plugin.

Returns: The specified render-engine

◆ EngineCount()

unsigned int EngineCount ( ) const

Get the number of available render-engines.

Returns: the number of available render-engines

◆ HasEngine()

bool HasEngine ( const std::string & _name ) const

Determine if a render-engine with the given name is avaiable. It also checks the list of default engines supplied by ign-rendering.

Parameters

[in] _name Name of the desired render-engine

Returns: True if the specified render-engine is available

◆ IsEngineLoaded()

bool IsEngineLoaded ( const std::string & _name ) const

Determine if a render-engine with the given name is already loaded.

Parameters

[in] _name Name of the desired render-engine

Returns: True if the specified render-engine is loaded.

◆ LoadedEngines()

std::vector<std::string> LoadedEngines ( ) const

Get the list of all engines already loaded.

Returns: Names of all loaded engines.

◆ RegisterEngine()

void RegisterEngine	(	const std::string &	_name,
		RenderEngine *	_engine
	)

Register a new render-engine under the given name. If the given name is already in use, the render-engine will not be registered.

Parameters

[in]	_name	Name the render-engine will be registered under
[in]	_engine	Render-engine to be registered

◆ SetPluginPaths()

void SetPluginPaths ( const std::list< std::string > & _paths )

Set the plugin paths from which render engines can be loaded.

Parameters

[in] _paths The list of the plugin paths

◆ UnloadEngine()

bool UnloadEngine ( const std::string & _name )

Unload the render-engine with the given name. If the no render-engine is registered under the given name, false will be returned.

Parameters

[in] _name Name of the desired render-engine

Returns: True if the engine is unloaded

◆ UnloadEngineAt()

bool UnloadEngineAt ( unsigned int _index )

Unload the render-engine at the given index. If the no render-engine is registered under the given name, false will be returned.

Parameters

[in] _index Index of the desired render-engine

Returns: True if the engine is unloaded

◆ UnregisterEngine() [1/2]

void UnregisterEngine ( const std::string & _name )

Unregister a render-engine registered under the given name. If no render-engine is registered under the given name no work will be done.

Parameters

[in] _name Name of the render-engine to unregister

◆ UnregisterEngine() [2/2]

void UnregisterEngine ( RenderEngine * _engine )

Unregister the given render-engine. If the given render-engine is not currently registered, no work will be done.

Parameters

[in] _engine Render-engine to unregister

◆ UnregisterEngineAt()

void UnregisterEngineAt ( unsigned int _index )

Unregister a render-engine at the given index. If the no render-engine is registered at the given index, no work will be done.

Parameters

[in] _index Index of the render-engine to unregister
