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 @CompositorWorkspace and @CompositorWorkspaceDef) 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 @PASS_SCENE, @PASS_QUAD, @PASS_CLEAR, @PASS_STENCIL, @PASS_RESOLVE
This is the definition. For the instantiation,

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

Creates an UAV buffer.

Parameters
nameName 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.
bindFlagsBitmask.

◆ 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
inputChannelInput channel # the buffer comes from.
nameName 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
renderTargetNameWe need the full name, not just the hash; so we can check whether it has the global_ prefix
rtIndexThe RT to address if it is intended to use with a 3D texture (or a cubemap or a 2D Array) @See 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
@See 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
nameThe 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
fullNameThe 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.
indexIndex 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.
textureSourceSource where the index must be used (eg. TEXTURE_LOCAL means mLocalTextureDefs)
Returns
IdString of the fullName paremeter, for convenience

Reimplemented in Ogre::CompositorShadowNodeDef.

◆ calculateNumPasses()

size_t Ogre::CompositorNodeDef::calculateNumPasses ( ) const

Calculates the total number of passes in this node.

◆ createBuffer()

const TextureGpu finalTarget,
VaoManager vaoManager 
)
staticinherited

◆ 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 
)
staticinherited

◆ 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
textureDefsArray of texture definitions
inOutTexContainerWhere we'll store the newly created RTs & textures
idUnique id in the case we want textures to have unique names (uniqueNames must be true)
uniqueNamesSet 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)
finalTargetThe final render target (usually the render window) we have to clone parameters from (eg. when using auto width & height, or fsaa settings)
renderSysThe 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.

Parameters
passDefNewly created pass to toy with.

Reimplemented in Ogre::CompositorShadowNodeDef.

CompositorNamedBufferVec inOutBufContainer,
const TextureGpu finalTarget,
RenderSystem renderSys,
const CompositorNodeVec connectedNodes,
const CompositorPassVec passes 
)
staticinherited

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

the RenderWindow) resolution

Parameters
textureDefsArray of texture definitions, so we know which ones depend on main RT's resolution
inOutTexContainerWhere we'll replace the RTs & textures
finalTargetThe final render target (usually the render window) we have to clone parameters from (eg. when using auto width & height, or fsaa settings)
renderSysThe RenderSystem to use
connectedNodesArray of connected nodes that may be using our buffers and need to be notified.
passesArray 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
textureDefsArray of texture definitions, so we know which ones depend on main RT's resolution
inOutTexContainerWhere we'll replace the RTs & textures
finalTargetThe final render target (usually the render window) we have to clone parameters from (eg. when using auto width & height, or fsaa settings)
renderSysThe RenderSystem to use

◆ recreateResizableTextures02()

static void Ogre::TextureDefinitionBase::recreateResizableTextures02 ( const TextureDefinitionVec textureDefs,
CompositorChannelVec inOutTexContainer,
const CompositorNodeVec connectedNodes,
const CompositorPassVec passes 
)
staticinherited

See recreateResizableTextures01 Updates involved RenderPassDescriptors.

Parameters
connectedNodesArray of connected nodes that may be using our textures and need to be notified.
passesArray 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 ( )
inherited

◆ removeBuffer()

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

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

◆ removeRenderTextureView()

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

◆ removeTexture()

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

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
nameName of the texture to remove.

Reimplemented from Ogre::TextureDefinitionBase.

◆ renameBuffer()

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

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.

◆ setNumLocalBufferDefinitions()
