Detailed Description

Compositor nodes are the core subject of compositing.

: They can define local textures and pass them to other nodes within the same workspace through their output channels. They can also receive textures through their input channels and send them through a different output channel to the next node(s). They can access global textures defined by the Workspace they belong to, but can't pass them to the output channels.

: How nodes input and output channels are wired together depends on the Workspace (See and ) A node cannot receive input from two nodes in the same channel, but it can send output to more than one node using the same output channel.

: A node whose workspace didn't connect all of its input channels cannot be executed, and unless it is disabled, the Compositor will be unable to render.

: The other core feature of nodes (besides textures and channels) is that they perform passes on RTs. A pass is the basic way to render: it can be a , , , ,

: This is the definition. For the instantiation,

Remarks: We own the local textures, so it's our job to destroy them

		size_t	numElements,
		uint32	bytesPerElement,
		uint32	bindFlags,
		float	widthFactor,
		float	heightFactor
	)

inherited

Creates an UAV buffer.

Parameters

name	Name to give to this buffer for referencing it locally from this scope. Duplicate names (including names from addBufferInput) will raise an exception when trying to instantiate the workspace.
bindFlags	Bitmask.

See also: BufferBindFlags

Parameters

widthFactor

See also: BufferDefinition::widthFactor

Parameters

heightFactor

See also: BufferDefinition::widthFactor

◆ addBufferInput()

virtual void Ogre::TextureDefinitionBase::addBufferInput	(	size_t	inputChannel,
		IdString	name
	)

virtualinherited

Buffers.

Specifies that buffer incoming from channel 'inputChannel' will be referenced by the name 'name'

Remarks: Don't leave gaps. (i.e. set channel 0 & 2, without setting channel 1) It's ok to map them out of order (i.e. set channel 2, then 0, then 1)

Parameters

inputChannel	Input channel # the buffer comes from.
name	Name to give to this buffer for referencing it locally from this scope. Duplicate names (including names from addBufferDefinition) will raise an exception when trying to instantiate the workspace.

Reimplemented in Ogre::CompositorShadowNodeDef.

◆ addRenderTextureView()

inherited

◆ addTargetPass()

CompositorTargetDef* Ogre::CompositorNodeDef::addTargetPass	(	const String &	renderTargetName,
		uint32	rtIndex = `0`
	)

Adds a new Target pass.

Remarks: WARNING: Calling this function may invalidate all previous returned pointers unless you've properly called setNumTargetPass

Parameters

renderTargetName	We need the full name, not just the hash; so we can check whether it has the global_ prefix
rtIndex	The RT to address if it is intended to use with a 3D texture (or a cubemap or a 2D Array) CompositorPassDef::mRtIndex. Default: 0

◆ addTextureDefinition()

TextureDefinition* Ogre::TextureDefinitionBase::addTextureDefinition ( const String & name )

inherited

Creates a TextureDefinition with a given name, must be unique.

Remarks: WARNING: Calling this function may invalidate all previous returned pointers unless you've properly called setLocalTextureDefinitions

: addTextureSourceName remarks for what it can throw

: Textures are local when the derived class is a Node definition, and it's global when the derived class is a Workspace definition

Parameters

name	The name of the texture. Names are usually valid only throughout this node. We need the name, not its hash because we need to validate the global_ prefix is used correctly.

◆ addTextureSourceName()

virtual IdString Ogre::TextureDefinitionBase::addTextureSourceName	(	const String &	name,
		size_t	index,
		TextureSource	textureSource
	)

virtualinherited

Adds a texture name, whether a real one or an alias, and where to grab it from.

Remarks: Throws if a texture with same name already exists, or if the name makes improper usage of the 'global' prefix.

This is a generic way to add input channels, by calling:

addTextureSourceName( "myRT", 0, TextureDefinitionBase::TEXTURE_INPUT );

You're assigning an alias named "myRT" to channel Input #0 For local or global textures, the index parameter documentation

Parameters

fullName	The name of the texture. Names are usually valid only throughout this node. We need the name, not its hash because we need to validate the global_ prefix is used correctly.
index	Index in the container where the texture is located, eg. this->mLocalTextureDefs[index] for local textures, workspace->mLocalTextureDefs[index] for global textures, and this->mInTextures[index] for input channels.
textureSource	Source where the index must be used (eg. TEXTURE_LOCAL means mLocalTextureDefs)

Returns: IdString of the fullName paremeter, for convenience

Reimplemented in Ogre::CompositorShadowNodeDef.

◆ createBuffer()

		const TextureGpu *	finalTarget,
		VaoManager *	vaoManager

◆ createBuffers()

static void Ogre::TextureDefinitionBase::createBuffers	(	const BufferDefinitionVec &	bufferDefs,
		CompositorNamedBufferVec &	inOutBufContainer,
		const TextureGpu *	finalTarget,
		RenderSystem *	renderSys
	)

staticinherited

Utility function to create the buffers based on a given set of buffer definitions and put them in a container.

Remarks: Useful because both Workspace & CompositorNode share the same functionality (create global/local buffers respectively) without having to create a whole base class just for one function. It's confusing that Nodes & Workspace would share the same base class, as if they were the same base object or share similar functionality (when in fact, workspace manages nodes)

◆ createTexture()

static CompositorChannel Ogre::TextureDefinitionBase::createTexture	(	const TextureDefinition &	textureDef,
		const String &	texName,
		const TextureGpu *	finalTarget,
		RenderSystem *	renderSys
	)

◆ createTextures()

static void Ogre::TextureDefinitionBase::createTextures	(	const TextureDefinitionVec &	textureDefs,
		CompositorChannelVec &	inOutTexContainer,
		IdType	id,
		const TextureGpu *	finalTarget,
		RenderSystem *	renderSys
	)

staticinherited

Utility function to create the textures based on a given set of texture definitions and put them in a container.

Remarks: Useful because both Workspace & CompositorNode share the same functionality (create global/local textures respectively) without having to create a whole base class just for one function. It's confusing that Nodes & Workspace would share the same base class, as if they were the same base object or share similar functionality (when in fact, workspace manages nodes)

Parameters

textureDefs	Array of texture definitions
inOutTexContainer	Where we'll store the newly created RTs & textures
id	Unique id in the case we want textures to have unique names (uniqueNames must be true)
uniqueNames	Set to true if each RT will have a unique name based on given Id, or we don't. The latter is useful for global textures (let them get access through materials)
finalTarget	The final render target (usually the render window) we have to clone parameters from (eg. when using auto width & height, or fsaa settings)
renderSys	The RenderSystem to use

◆ destroyBuffers()

static void Ogre::TextureDefinitionBase::destroyBuffers	(	const BufferDefinitionVec &	bufferDefs,
		CompositorNamedBufferVec &	inOutBufContainer,
		RenderSystem *	renderSys
	)

staticinherited

See also: createBuffers We need the definition because, unlike textures, the container passed in may contain textures that were not created by us (i.e. global & input textures) that we shouldn't delete. It is illegal for two buffers to have the same name, so it's invalid that a e.g. an input and a local texture would share the same name.

staticinherited

Destroys & recreates only the buffers that depend on the main RT (i.e.

the RenderWindow) resolution

Parameters

textureDefs	Array of texture definitions, so we know which ones depend on main RT's resolution
inOutTexContainer	Where we'll replace the RTs & textures
finalTarget	The final render target (usually the render window) we have to clone parameters from (eg. when using auto width & height, or fsaa settings)
renderSys	The RenderSystem to use
connectedNodes	Array of connected nodes that may be using our buffers and need to be notified.
passes	Array of Compositor Passes which may contain the texture being recreated When the pointer is null, we don't iterate through it.

◆ recreateResizableTextures01()

static void Ogre::TextureDefinitionBase::recreateResizableTextures01	(	const TextureDefinitionVec &	textureDefs,
		CompositorChannelVec &	inOutTexContainer,
		const TextureGpu *	finalTarget
	)

staticinherited

Destroys & recreates only the textures that depend on the main RT (e.g.

the Render Window) resolution.

Remarks: This is divided in two steps: recreateResizableTextures01 & recreateResizableTextures02 since in some cases in RenderPassDescriptor, setting up MRT and depth textures requires all textures to be up to date, otherwise validation errors would occur since we'll have partial data (e.g. MRT 0 is 1024x768 while MRT 1 is 800x600)

Parameters

textureDefs	Array of texture definitions, so we know which ones depend on main RT's resolution
inOutTexContainer	Where we'll replace the RTs & textures
finalTarget	The final render target (usually the render window) we have to clone parameters from (eg. when using auto width & height, or fsaa settings)
renderSys	The RenderSystem to use

◆ recreateResizableTextures02()

static void Ogre::TextureDefinitionBase::recreateResizableTextures02	(	const TextureDefinitionVec &	textureDefs,
		CompositorChannelVec &	inOutTexContainer,
		const CompositorNodeVec &	connectedNodes,

	)

staticinherited

See recreateResizableTextures01 Updates involved RenderPassDescriptors.

Parameters

connectedNodes	Array of connected nodes that may be using our textures and need to be notified.
passes	Array of Compositor Passes which may contain the texture being recreated When the pointer is null, we don't iterate through it.

◆ removeAllRenderTextureViews()

void Ogre::TextureDefinitionBase::removeAllRenderTextureViews ( void )

inherited

◆ removeBuffer()

virtual void Ogre::TextureDefinitionBase::removeBuffer ( IdString name )

Remove a buffer. Buffer can come from an input channel, or a locally defined one.

◆ removeRenderTextureView()

void Ogre::TextureDefinitionBase::removeRenderTextureView ( IdString name )

inherited

◆ removeTexture()

virtual void Ogre::CompositorNodeDef::removeTexture ( IdString name )

virtual

WARNING: Be very careful with this function.

Removes a texture. If the texture is from an input channel (TEXTURE_INPUT), the input channel is removed. If the texture is a local definition (TEXTURE_LOCAL) the texture definition is removed and all the references to mLocalTextureDefs[i+1] ... mLocalTextureDefs[i+n] are updated. However, the output channels will now contain an invalid index and will only be removed if it was the last output channel (since we can't alter the order). It is your responsability to call CompositorNodeDef::mapOutputChannel again with a valid texture name to the channel it was occupying. If the texture is a global texture (TEXTURE_GLOBAL), the global texture can no longer be accessed until addTextureSourceName( name, 0, TEXTURE_GLOBAL ) is called again.

Parameters

name	Name of the texture to remove.

Reimplemented from Ogre::TextureDefinitionBase.

◆ renameBuffer()

void Ogre::TextureDefinitionBase::renameBuffer	(	IdString	oldName,
		const String &	newName
	)

Buffer can come from an input channel, or a locally defined one.

◆ renameTexture()

void Ogre::TextureDefinitionBase::renameTexture	(	IdString	oldName,
		const String &	newName

inherited

Changes the name of a texture.

Texture can come from an input channel, be a global texture, or a locally defined one. You can't rename a global texture to avoid the "global_" prefix, or add the "global_" prefix to a texture that wasn't global.

Remarks: Calling this function is not obligatory, but recommended

Parameters

numPasses The number of output channels expected to contain.

◆ setNumTargetPass()

void Ogre::CompositorNodeDef::setNumTargetPass ( size_t numPasses )

inline

Reserves enough memory for all passes.

Remarks: Calling this function is obligatory, otherwise unexpected crashes may occur. CompositorTargetDef doesn't follow the Rule of Three.

Parameters

numPasses The number of passes expected to contain.

◆ setStartEnabled()

void Ogre::CompositorNodeDef::setStartEnabled ( bool enabled )

inline

Whether the node should be start as enabled when instantiated.

◆ setupTexture()

static void Ogre::TextureDefinitionBase::setupTexture	(	TextureGpu *	tex,
		const TextureDefinition &	textureDef,
		const TextureGpu *	finalTarget
	)
