Detailed Description

Class representing a Compositor object.

Compositors provide the means to flexibly "composite" the final rendering result from multiple scene renders and intermediate operations like rendering fullscreen quads. This makes it possible to apply postfilter effects, HDRI postprocessing, and shadow effects to a Viewport.

Member Typedef Documentation

◆ Techniques

typedef std::vector<CompositionTechnique *> Ogre::Compositor::Techniques

Data types for internal lists.

◆ TechniqueIterator

typedef VectorIterator<Techniques> Ogre::Compositor::TechniqueIterator

Constructor & Destructor Documentation

◆ Compositor()

Ogre::Compositor::Compositor	(	ResourceManager *	creator,
		const String &	name,
		ResourceHandle	handle,
		const String &	group,
		bool	isManual = `false`,
		ManualResourceLoader *	loader = `0`
	)

◆ ~Compositor()

Ogre::Compositor::~Compositor ( )

Member Function Documentation

◆ createTechnique()

CompositionTechnique * Ogre::Compositor::createTechnique ( )

Create a new technique, and return a pointer to it.

◆ removeTechnique()

void Ogre::Compositor::removeTechnique ( size_t idx )

Remove a technique.

It will also be destroyed.

◆ getTechnique()

CompositionTechnique * Ogre::Compositor::getTechnique ( size_t idx ) const

inline

Get a technique.

◆ getNumTechniques()

size_t Ogre::Compositor::getNumTechniques ( ) const

inline

Get the number of techniques.

◆ removeAllTechniques()

void Ogre::Compositor::removeAllTechniques ( )

Remove all techniques.

◆ getTechniqueIterator()

TechniqueIterator Ogre::Compositor::getTechniqueIterator ( void )

Get an iterator over the Techniques in this compositor.

◆ getSupportedTechnique() [1/2]

CompositionTechnique * Ogre::Compositor::getSupportedTechnique ( size_t idx ) const

inline

Get a supported technique.

The supported technique list is only available after this compositor has been compiled, which typically happens on loading it. Therefore, if this method returns an empty list, try calling Compositor::load.

◆ getNumSupportedTechniques()

size_t Ogre::Compositor::getNumSupportedTechniques ( ) const

inline

Get the number of supported techniques.

The supported technique list is only available after this compositor has been compiled, which typically happens on loading it. Therefore, if this method returns an empty list, try calling Compositor::load.

◆ getSupportedTechniqueIterator()

TechniqueIterator Ogre::Compositor::getSupportedTechniqueIterator ( void )

Gets an iterator over all the Techniques which are supported by the current card.

The supported technique list is only available after this compositor has been compiled, which typically happens on loading it. Therefore, if this method returns an empty list, try calling Compositor::load.

◆ getSupportedTechnique() [2/2]

CompositionTechnique * Ogre::Compositor::getSupportedTechnique ( const String & schemeName = BLANKSTRING )

Get a pointer to a supported technique for a given scheme.

If there is no specific supported technique with this scheme name, then the first supported technique with no specific scheme will be returned.

Parameters

schemeName The scheme name you are looking for. Blank means to look for techniques with no scheme associated

◆ getTextureInstanceName()

const String & Ogre::Compositor::getTextureInstanceName	(	const String &	name,
		size_t	mrtIndex
	)

Get the instance name for a global texture.

Parameters

name	The name of the texture in the original compositor definition
mrtIndex	If name identifies a MRT, which texture attachment to retrieve

Returns: The instance name for the texture, corresponds to a real texture

◆ getTextureInstance()

const TexturePtr & Ogre::Compositor::getTextureInstance	(	const String &	name,
		size_t	mrtIndex
	)

Get the instance of a global texture.

Parameters

name	The name of the texture in the original compositor definition
mrtIndex	If name identifies a MRT, which texture attachment to retrieve

Returns: The texture pointer, corresponds to a real texture

◆ getRenderTarget()

RenderTarget * Ogre::Compositor::getRenderTarget	(	const String &	name,
		int	slice = `0`
	)

Get the render target for a given render texture name.

You can use this to add listeners etc, but do not use it to update the targets manually or any other modifications, the compositor instance is in charge of this.
