Detailed Description

Shadow Nodes are special nodes (not to be confused with.

See also: CompositorNode) that are only used for rendering shadow maps. Normal Compositor Nodes can share or own a ShadowNode. The ShadowNode will render the scene enough times to fill all shadow maps so the main scene pass can use them.

: ShadowNode are very flexible compared to Ogre 1.x; as they allow mixing multiple shadow camera setups for different lights.

Member Function Documentation

◆ _validateAndFinish()

virtual void Ogre::CompositorShadowNodeDef::_validateAndFinish ( void )

virtual

Checks that paremeters are correctly set, and finalizes whatever needs to be done, probably because not enough data was available at the time of creation.

Remarks: If possible, try to validate parameters at creation time to avoid delaying when the error shows up. We should validate here if it's not possible to validate at any other time or if it's substantially easier to do so here.

◆ addBufferDefinition()

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

virtual

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 from Ogre::TextureDefinitionBase.

◆ addRenderTextureView()

RenderTargetViewDef* Ogre::TextureDefinitionBase::addRenderTextureView ( IdString name )

inherited

◆ addShadowTextureDefinition()

ShadowTextureDefinition* Ogre::CompositorShadowNodeDef::addShadowTextureDefinition	(	size_t	lightIdx,
		size_t	split,
		const String &	name,
		const Vector2 &	uvOffset,
		const Vector2 &	uvLength,
		uint8	arrayIdx
	)

Adds a new ShadowTexture definition.

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

Parameters

lightIdx	Nth Closest Light to assign this texture to. Must be unique unless split is different.
split	Split for the given light. Only valid for CSM/PSSM shadow maps. Must be unique for the same lightIdx.
name	Name to a declared texture that will hold our shadow map. Must not contain the "global_" prefix.
uvOffset	Values in range [0; 1] to determine what region of the texture will hold our shadow map (i.e. UV atlas). Use Vector2::ZERO if it covers the entire texture.
uvLength	Values in range [0; 1] to determine what region of the texture will hold our shadow map (i.e. UV atlas). Use Vector2::UNIT_SCALE if it covers the entire texture.
arrayIdx	If the texture is an array texture, index to the slice that holds our shadow map.

◆ addTargetPass()

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

inherited

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::CompositorShadowNodeDef::addTextureSourceName	(	const String &	name,

◆ 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()

		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)

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

◆ removeRenderTextureView()

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

inherited

◆ removeTexture()

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

virtualinherited

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.

Changes the name of a buffer.

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.

◆ setDefaultTechnique()

void Ogre::CompositorShadowNodeDef::setDefaultTechnique ( ShadowMapTechniques techn )

inline

References Ogre::ShadowTextureDefinition::arrayIdx, Ogre::ShadowTextureDefinition::split, Ogre::ShadowTextureDefinition::uvLength, and Ogre::ShadowTextureDefinition::uvOffset.

◆ setNumLocalBufferDefinitions()

void Ogre::TextureDefinitionBase::setNumLocalBufferDefinitions ( size_t numTDs )

inlineinherited

Reserves enough memory for all texture definitions.

Remarks: Calling this function is not obligatory, but recommended

Parameters

numPasses The number of texture definitions expected to contain.

◆ setNumLocalTextureDefinitions()

void Ogre::TextureDefinitionBase::setNumLocalTextureDefinitions ( size_t numTDs )

inlineinherited

Reserves enough memory for all texture definitions.

Remarks: Calling this function is not obligatory, but recommended

Parameters

numPasses The number of texture definitions expected to contain.

◆ setNumOutputBufferChannels()

void Ogre::CompositorNodeDef::setNumOutputBufferChannels ( size_t numOuts )

inlineinherited

Reserves enough memory for all output channel mappings (efficient allocation, better than using linked lists or other containers with two level of indirections)

Remarks: Calling this function is not obligatory, but recommended

Parameters

numPasses The number of output buffer channels expected to contain.

◆ setNumOutputChannels()

void Ogre::CompositorNodeDef::setNumOutputChannels ( size_t numOuts )

inlineinherited

Reserves enough memory for all output channel mappings (efficient allocation, better than using linked lists or other containers with two level of indirections)

Remarks: Calling this function is not obligatory, but recommended

Parameters

numPasses The number of output channels expected to contain.

◆ setNumShadowTextureDefinitions()

void Ogre::CompositorShadowNodeDef::setNumShadowTextureDefinitions ( size_t numTex )

Reserves enough memory for all texture definitions.

Remarks: Calling this function is not obligatory, but recommended

Parameters

numTex The number of shadow textures expected to contain.

◆ setNumTargetPass()

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

inlineinherited

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 )

inlineinherited

Whether the node should be start as enabled when instantiated.
