Member Function Documentation

virtual void Ogre::CompositorInstance::_compileOutputOperation ( TargetOperation finalState)
virtual

Compile the final (output) operation.

This is done separately because this is combined with the input in chained filters.

virtual void Ogre::CompositorInstance::_compileTargetOperations ( CompiledState compiledState)
virtual

Recursively collect target states (except for final Pass).

Parameters
compiledStateThis vector will contain a list of TargetOperation objects
void Ogre::CompositorInstance::_fireNotifyMaterialRender ( uint32  pass_id,
MaterialPtr mat 
)

Notify listeners of a material render.

void Ogre::CompositorInstance::_fireNotifyMaterialSetup ( uint32  pass_id,
MaterialPtr mat 
)

Notify listeners of a material compilation.

void Ogre::CompositorInstance::_fireNotifyResourcesCreated ( bool  forResizeOnly)

Notify listeners of a material render.

void Ogre::CompositorInstance::addListener ( Listener l)

Add a listener.

Listeners provide an interface to "listen in" to to render system operations executed by this CompositorInstance so that materials can be programmatically set up.

See also
CompositorInstance::Listener
virtual void Ogre::CompositorInstance::collectPasses ( TargetOperation finalState,
CompositionTargetPass target 
)
privatevirtual

Collect rendering passes.

Here, passes are converted into render target operations and queued with queueRenderSystemOp.

MaterialPtr Ogre::CompositorInstance::createLocalMaterial ( const String srcName)
private

Create a local dummy material with one technique but no passes.

The material is detached from the Material Manager to make sure it is destroyed when going out of scope.

void Ogre::CompositorInstance::createResources ( bool  forResizeOnly)
private

Create local rendertextures and other resources.

Builds mLocalTextures.

void Ogre::CompositorInstance::deriveTextureRenderTargetOptions ( const String texname,
bool *  hwGammaWrite,
uint fsaa,
String fsaaHint 
)
private

Search for options like AA and hardware gamma which we may want to inherit from the main render target to which we're attached.

void Ogre::CompositorInstance::freeResources ( bool  forResizeOnly,
bool  clearReserveTextures 
)
private

Destroy local rendertextures and other resources.

CompositorChain* Ogre::CompositorInstance::getChain ( )

Get Chain that this instance is part of.

Compositor* Ogre::CompositorInstance::getCompositor ( )

Get Compositor of which this is an instance.

bool Ogre::CompositorInstance::getEnabled ( )

Get enabled flag.

String Ogre::CompositorInstance::getMRTTexLocalName ( const String baseName,
size_t  attachment 
)
private

Util method for assigning a local texture name to a MRT attachment.

RenderTarget* Ogre::CompositorInstance::getRenderTarget ( const String name)

Get the render target for a given render texture name.

Remarks
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.
const String& Ogre::CompositorInstance::getScheme ( ) const
inline

Returns the name of the scheme this compositor is using.

Definition at line 241 of file OgreCompositorInstance.h.

const String& Ogre::CompositorInstance::getSourceForTex ( const String name,
size_t  mrtIndex = 0 
)
private

Get source texture name for a named local texture.

Parameters
nameThe local name of the texture as given to it in the compositor
mrtIndexFor MRTs, which attached surface to retrieve
RenderTarget* Ogre::CompositorInstance::getTargetForTex ( const String name)
private

Get RenderTarget for a named local texture.

CompositionTechnique* Ogre::CompositorInstance::getTechnique ( )

Get CompositionTechnique used by this instance.

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

Get the instance of a local texture.

Note
Textures are only valid when local textures have been loaded, which in practice means that the compositor instance is active. Calling this method at other times will return null pointers. Note that since textures are cleaned up aggressively, this pointer is not guaranteed to stay the same if you disable and re-enable the compositor instance.
Parameters
nameThe name of the texture in the original compositor definition
mrtIndexIf name identifies a MRT, which texture attachment to retrieve
Returns
The texture pointer, corresponds to a real texture
const String& Ogre::CompositorInstance::getTextureInstanceName ( const String name,
size_t  mrtIndex 
)

Get the instance name for a local texture.

Note
It is only valid to call this when local textures have been loaded, which in practice means that the compositor instance is active. Calling it at other times will cause an exception. Note that since textures are cleaned up aggressively, this name is not guaranteed to stay the same if you disable and re-enable the compositor instance.
Parameters
nameThe name of the texture in the original compositor definition
mrtIndexIf name identifies a MRT, which texture attachment to retrieve
Returns
The instance name for the texture, corresponds to a real texture
void Ogre::CompositorInstance::notifyResized ( )

Notify this instance that the primary surface has been resized.

Remarks
This will allow the instance to recreate its resources that are dependent on the size.

void Ogre::CompositorInstance::removeListener ( Listener l)

See also
CompositorInstance::Listener
void Ogre::CompositorInstance::setEnabled ( bool  value)

Set enabled flag.

The compositor instance will only render if it is enabled, otherwise it is pass-through.

void Ogre::CompositorInstance::setScheme ( const String schemeName,
bool  reuseTextures = true 
)

Pick a technique to use to render this compositor based on a scheme.

Remarks
If there is no specific supported technique with this scheme name, then the first supported technique with no specific scheme will be used.
See also
CompositionTechnique::setSchemeName
Parameters
schemeNameThe scheme to use
reuseTexturesIf textures have already been created for the current technique, whether to try to re-use them if sizes & formats match. Note that for this feature to be of benefit, the textures must have been created with the 'pooled' option enabled.
void Ogre::CompositorInstance::setTechnique ( CompositionTechnique tech,
bool  reuseTextures = true 
)

Change the technique we're using to render this compositor.

Parameters
techThe technique to use (must be supported and from the same Compositor)
reuseTexturesIf textures have already been created for the current technique, whether to try to re-use them if sizes & formats match.
