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 Function Documentation

virtual void Ogre::Resource::_dirtyState ( ) [virtual, inherited]

Manually mark the state of this resource as having been changed.

Remarks:: You only need to call this from outside if you explicitly want derived objects to think this object has changed.

See also:: getStateCount.

virtual void Ogre::Resource::_fireLoadingComplete ( bool wasBackgroundLoaded ) [virtual, inherited]

Firing of loading complete event.

Remarks:: You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

Parameters:

wasBackgroundLoaded

Whether this was a background loaded event

virtual void Ogre::Resource::_firePreparingComplete ( bool wasBackgroundLoaded ) [virtual, inherited]

Firing of preparing complete event.

Remarks:: You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

Parameters:

wasBackgroundLoaded

Whether this was a background loaded event

virtual void Ogre::Resource::_fireUnloadingComplete ( void ) [virtual, inherited]

Firing of unloading complete event.

Remarks:: You should call this from the thread that runs the main frame loop to avoid having to make the receivers of this event thread-safe. If you use Ogre's built in frame loop you don't need to call this yourself.

virtual void Ogre::Resource::_notifyOrigin ( const String & origin ) [virtual, inherited]

Notify this resource of it's origin.

Definition at line 420 of file OgreResource.h.

virtual void Ogre::Resource::addListener ( Listener * lis ) [virtual, inherited]

Register a listener on this resource.

See also:: Resource::Listener

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

size_t Ogre::Compositor::calculateSize ( void ) const [protected, virtual]

Calculate the size of a resource; this will only be called after 'load'.

Implements Ogre::Resource.

virtual void Ogre::Resource::changeGroupOwnership ( const String & newGroup ) [virtual, inherited]

Change the resource group ownership of a Resource.

Remarks:: This method is generally reserved for internal use, although if you really know what you're doing you can use it to move this resource from one group to another.

Parameters:

newGroup

Name of the new group

static void Ogre::StringInterface::cleanupDictionary ( ) [static, inherited]

Cleans up the static 'msDictionary' required to reset Ogre, otherwise the containers are left with invalid pointers, which will lead to a crash as soon as one of the ResourceManager implementers (e.g.

MaterialManager) initializes.

void Ogre::Compositor::compile ( ) [protected]

Check supportedness of techniques.

virtual void Ogre::StringInterface::copyParametersTo ( StringInterface * dest ) const [virtual, inherited]

Method for copying this object's parameters to another object.

Remarks:: This method takes the values of all the object's parameters and tries to set the same values on the destination object. This provides a completely type independent way to copy parameters to other objects. Note that because of the String manipulation involved, this should not be regarded as an efficient process and should be saved for times outside of the rendering loop.

: Any unrecognised parameters will be ignored as with setParameter method.

Parameters:

dest

Pointer to object to have it's parameters set the same as this object.

Definition at line 301 of file OgreStringInterface.h.

References Ogre::ParamDictionary::mParamDefs, and Ogre::StringInterface::setParameter().

void Ogre::Compositor::createGlobalTextures ( ) [private]

Create global rendertextures.

bool Ogre::StringInterface::createParamDictionary ( const String & className ) [protected, inherited]

Internal method for creating a parameter dictionary for the class, if it does not already exist.

Remarks:: This method will check to see if a parameter dictionary exist for this class yet, and if not will create one. NB you must supply the name of the class (RTTI is not used or performance).

Parameters:

className

the name of the class using the dictionary

Returns:: true if a new dictionary was created, false if it was already there

Definition at line 184 of file OgreStringInterface.h.

References OGRE_LOCK_MUTEX.

CompositionTechnique* Ogre::Compositor::createTechnique ( )

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

virtual void Ogre::Resource::escalateLoading ( ) [virtual, inherited]

Escalates the loading of a background loaded resource.

Remarks:: If a resource is set to load in the background, but something needs it before it's been loaded, there could be a problem. If the user of this resource really can't wait, they can escalate the loading which basically pulls the loading into the current thread immediately. If the resource is already being loaded but just hasn't quite finished then this method will simply wait until the background load is complete.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

void Ogre::Compositor::freeGlobalTextures ( ) [private]

Destroy global rendertextures.

virtual ResourceManager* Ogre::Resource::getCreator ( void ) [virtual, inherited]

Gets the manager which created this resource.

Definition at line 411 of file OgreResource.h.

virtual const String& Ogre::Resource::getGroup ( void ) const [virtual, inherited]

Gets the group which this resource is a member of.

Definition at line 399 of file OgreResource.h.

virtual ResourceHandle Ogre::Resource::getHandle ( void ) const [virtual, inherited]

Reimplemented in Ogre::SkeletonInstance.

Gets resource name.

Reimplemented in Ogre::SkeletonInstance.

Definition at line 312 of file OgreResource.h.

size_t Ogre::Compositor::getNumSupportedTechniques ( )

Get the number of supported techniques.

Remarks:: 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.

size_t Ogre::Compositor::getNumTechniques ( )

Get the number of techniques.

virtual const String& Ogre::Resource::getOrigin ( void ) const [virtual, inherited]

Get the origin of this resource, e.g.

a script file name.

Remarks:: This property will only contain something if the creator of this resource chose to populate it. Script loaders are advised to populate it.

Definition at line 418 of file OgreResource.h.

const ParamDictionary* Ogre::StringInterface::getParamDictionary ( void ) const [inherited]

Definition at line 222 of file OgreStringInterface.h.

ParamDictionary* Ogre::StringInterface::getParamDictionary ( void ) [inherited]

Retrieves the parameter dictionary for this class.

Remarks:: Only valid to call this after createParamDictionary.

Returns:: Pointer to ParamDictionary shared by all instances of this class which you can add parameters to, retrieve parameters etc.

Definition at line 217 of file OgreStringInterface.h.

virtual String Ogre::StringInterface::getParameter ( const String & name ) const [virtual, inherited]

Generic parameter retrieval method.

Remarks:: Call this method with the name of a parameter to retrieve a string-format value of the parameter in question. If in doubt, check the parameter definition in the list returned from getParameters for the type of this parameter. If you like you can use StringConverter to convert this string back into a native type.

Parameters:

name

The name of the parameter to get

Returns:: String value of parameter, blank if not found

Definition at line 270 of file OgreStringInterface.h.

References Ogre::ParamCommand::doGet(), and Ogre::ParamDictionary::getParamCommand().

const ParameterList& Ogre::StringInterface::getParameters ( void ) const [inherited]

Retrieves a list of parameters valid for this object.

Returns:: A reference to a static list of ParameterDef objects.

RenderTarget* Ogre::Compositor::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.

virtual size_t Ogre::Resource::getSize ( void ) const [virtual, inherited]

Retrieves info about the size of the resource.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 301 of file OgreResource.h.

virtual size_t Ogre::Resource::getStateCount ( ) const [virtual, inherited]

Returns the number of times this resource has changed state, which generally means the number of times it has been loaded.

Objects that build derived data based on the resource can check this value against a copy they kept last time they built this derived data, in order to know whether it needs rebuilding. This is a nice way of monitoring changes without having a tightly-bound callback.

Definition at line 429 of file OgreResource.h.

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

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

Remarks:: 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

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

Get a supported technique.

Remarks:: 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.

TechniqueIterator Ogre::Compositor::getSupportedTechniqueIterator ( void )

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

Remarks:: 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.

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

Get a technique.

TechniqueIterator Ogre::Compositor::getTechniqueIterator ( void )

Get an iterator over the Techniques in this compositor.

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

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

virtual bool Ogre::Resource::isBackgroundLoaded ( void ) const [virtual, inherited]

Returns whether this Resource has been earmarked for background loading.

Remarks:: This option only makes sense when you have built Ogre with thread support (OGRE_THREAD_SUPPORT). If a resource has been marked for background loading, then it won't load on demand like normal when load() is called. Instead, it will ignore request to load() except if the caller indicates it is the background loader. Any other users of this resource should check isLoaded(), and if that returns false, don't use the resource and come back later.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 365 of file OgreResource.h.

virtual bool Ogre::Resource::isLoaded ( void ) const [virtual, inherited]

Returns true if the Resource has been loaded, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 324 of file OgreResource.h.

virtual bool Ogre::Resource::isReloadable ( void ) const [virtual, inherited]

Returns true if the Resource is reloadable, false otherwise.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 282 of file OgreResource.h.

virtual void Ogre::Resource::load ( bool backgroundThread = false ) [virtual, inherited]

Loads the resource, if it is not already.

Remarks:: If the resource is loaded from a file, loading is automatic. If not, if for example this resource gained it's data from procedural calls rather than loading from a file, then this resource will not reload on it's own.

Parameters:

backgroundThread

Indicates whether the caller of this method is the background resource loading thread.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

virtual void Ogre::Resource::postLoadImpl ( void ) [protected, virtual, inherited]

Internal hook to perform actions after the load process, but before the resource has been marked as fully loaded.

Note:: Mutex will have already been acquired by the loading thread. Also, this call will occur even when using a ManualResourceLoader (when loadImpl is not actually called)

Reimplemented in Ogre::Mesh.

Definition at line 189 of file OgreResource.h.

virtual void Ogre::Resource::postUnloadImpl ( void ) [protected, virtual, inherited]

Internal hook to perform actions after the unload process, but before the resource has been marked as fully unloaded.

Note:: Mutex will have already been acquired by the unloading thread.

Definition at line 199 of file OgreResource.h.

virtual void Ogre::Resource::preLoadImpl ( void ) [protected, virtual, inherited]

Internal hook to perform actions before the load process, but after the resource has been marked as 'loading'.

Note:: Mutex will have already been acquired by the loading thread. Also, this call will occur even when using a ManualResourceLoader (when loadImpl is not actually called)

Definition at line 182 of file OgreResource.h.

virtual void Ogre::Resource::prepare ( bool backgroundThread = false ) [virtual, inherited]

Prepares the resource for load, if it is not already.

One can call prepare() before load(), but this is not required as load() will call prepare() itself, if needed. When OGRE_THREAD_SUPPORT==1 both load() and prepare() are thread-safe. When OGRE_THREAD_SUPPORT==2 however, only prepare() is thread-safe. The reason for this function is to allow a background thread to do some of the loading work, without requiring the whole render system to be thread-safe. The background thread would call prepare() while the main render loop would later call load(). So long as prepare() remains thread-safe, subclasses can arbitrarily split the work of loading a resource between load() and prepare(). It is best to try and do as much work in prepare(), however, since this will leave less work for the main render thread to do and thus increase FPS.

Parameters:

backgroundThread

Whether this is occurring in a background thread

virtual void Ogre::Resource::prepareImpl ( void ) [protected, virtual, inherited]

Internal implementation of the meat of the 'prepare' action.

Reimplemented in Ogre::Material, Ogre::Mesh, and Ogre::PatchMesh.

Definition at line 203 of file OgreResource.h.

virtual void Ogre::Resource::preUnloadImpl ( void ) [protected, virtual, inherited]

Internal hook to perform actions before the unload process.

Note:: Mutex will have already been acquired by the unloading thread.

Definition at line 194 of file OgreResource.h.

virtual void Ogre::Resource::reload ( void ) [virtual, inherited]

Reloads the resource, if it is already loaded.

Remarks:: Calls unload() and then load() again, if the resource is already loaded. If it is not loaded already, then nothing happens.

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

void Ogre::Compositor::removeAllTechniques ( )

Remove all techniques.

virtual void Ogre::Resource::removeListener ( Listener * lis ) [virtual, inherited]

Remove a listener on this resource.

See also:: Resource::Listener

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

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

Remove a technique.

It will also be destroyed.

virtual void Ogre::Resource::setBackgroundLoaded ( bool bl ) [virtual, inherited]

Tells the resource whether it is background loaded or not.

Remarks:

See also:: Resource::isBackgroundLoaded . Note that calling this only defers the normal on-demand loading behaviour of a resource, it does not actually set up a thread to make sure the resource gets loaded in the background. You should use ResourceBackgroundLoadingQueue to manage the actual loading (which will call this method itself).

Reimplemented in Ogre::UnifiedHighLevelGpuProgram.

Definition at line 375 of file OgreResource.h.

virtual bool Ogre::StringInterface::setParameter	(	const String &	name,
		const String &	value
	)			`[virtual, inherited]`

Generic parameter setting method.

Remarks:: Call this method with the name of a parameter and a string version of the value to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters:

	name	The name of the parameter to set
	value	String value. Must be in the right format for the type specified in the parameter definition. See the StringConverter class for more information.

Returns:: true if set was successful, false otherwise (NB no exceptions thrown - tolerant method)

Referenced by Ogre::StringInterface::copyParametersTo().

virtual void Ogre::StringInterface::setParameterList ( const NameValuePairList & paramList ) [virtual, inherited]

Generic multiple parameter setting method.

Remarks:: Call this method with a list of name / value pairs to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters:

paramList

Name/value pair list
