class CompositorWorkspace
 

Detailed Description

@See CompositorWorkspace.

Workspace definitions assume all other definitions are already parsed as we need them to perform validation checks. Workspace definitions work by assigning aliases to each node. A node whose name is the same as its alias is called an implicit alias.

Remarks
Aliasing nodes allows having more than one instance of the same node.

Member Function Documentation

◆ _getChannelRoutes()

ChannelRouteList & Ogre::CompositorWorkspaceDef::_getChannelRoutes ( void  )
inline

Gets direct access to the channel route (aka the interconnections between all of our nodes).

Useful for advanced C++ users who want fine control of the connections.

Remarks
Incorrect manipulation of the channel routes can lead to glitches or crashes. Remember:
  1. Two nodes can't connect to the same node alias on the same channel
  2. Don't reference a node or alias that isn't in mAliasedNodes by the time the Workspace is instantiated
  3. A node that doesn't have all of its input channels connected is incomplete and should be disabled for the Workspace instance to be valid.

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.
See also
BufferBindFlags
Parameters
widthFactor

BufferDefinition::widthFactor
Parameters
heightFactor

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
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.

◆ addNodeAlias()

void Ogre::CompositorWorkspaceDef::addNodeAlias ( IdString  alias,
IdString  nodeName 
)

An alias is explicitly used when the user wants to use multiple, independent instances of the same node.

Each alias equals one instance. An implicit alias is when the name of the alias and it's node name match.

Remarks
When the name of the node and its alias are the same, it is said to be called an "implicit" alias. This function will throw if trying the alias is already taken by a node definition (except for implicit aliases) This function will throw if the alias is already in use.
Parameters
aliasName of the alias (instance). May be equal to nodeName.
nodeNameName of the node definition

◆ 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.

◆ clearAll()

void Ogre::CompositorWorkspaceDef::clearAll ( void  )

Clears everything: All node aliases, and their connections (including output connection).

Remarks
This function shouldn't be called while there are still instantiated workspaces It is safe to call this function while there are still workspaces, but you must call @Workspace::recreateAllNodes after you're done setting the new node connections.

◆ clearAllInterNodeConnections()

void Ogre::CompositorWorkspaceDef::clearAllInterNodeConnections ( void  )

Clears all the connection between channels of the nodes (.

See also
connect).
Remarks
  1. We don't clear the output connection (
See also
connectOutput,
clearOutputConnections)
  1. The node aliases (both implicit and explicit) will still exist. @See clearAll.
  2. A node with incomplete inputs should be disabled before the workspace is instantiated (
CompositorNodeDef::setStartEnabled). If the workspace has already been instantiated, the node instance should be disabled,
CompositorNode::setEnabled)
  1. It is safe to call this function while there are still workspaces, but you must call @Workspace::reconnectAllNodes after you're done setting the new node connections

◆ clearOutputConnections()

void Ogre::CompositorWorkspaceDef::clearOutputConnections ( void  )

Clears the connection from the "final output RenderTarget" (i.e.

usually the RenderWindow) that goes to the input channel of one of our nodes. @See connectOutput.

Remarks
  1. We don't clear other type of connections (
See also
connect,
clearAllInterNodeConnections)
  1. The node aliases (both implicit and explicit) will still exist. @See clearAll.
  2. A node with incomplete inputs should be disabled before the workspace is instantiated (
CompositorNodeDef::setStartEnabled). If the workspace has already been instantiated, the node instance should be disabled,
CompositorNode::setEnabled)
  1. It is safe to call this function while there are still workspaces, but you must call @Workspace::reconnectAllNodes after you're done setting the new node connections

◆ connect() [1/2]

void Ogre::CompositorWorkspaceDef::connect ( IdString  outNode,
IdString  inNode 
)

Connects all outputs channels from outNode to all input channels from inNode.

If the number of channels don't match, only the first N channels are set (where N is the minimum between outNode's output channels and inNode's input channels).

Remarks
If outNode & inNode are not yet aliased, an alias for them will be created.

◆ connect() [2/2]

void Ogre::CompositorWorkspaceDef::connect ( IdString  outNode,
uint32  outChannel,
IdString  inNode,
uint32  inChannel 
)

Connects outNode's output channel to inNode's input channel.

Remarks
This mapping will later be used to know how connections should be done when instantiating. @See CompositorNode::connectTo If outNode & inNode are not yet aliased, an alias for them will be created.

◆ connectBuffer() [1/2]

void Ogre::CompositorWorkspaceDef::connectBuffer ( IdString  outNode,
IdString  inNode 
)

Connects all output buffer channels from outNode to all input buffer channels from inNode.

If the number of channels don't match, only the first N channels are set (where N is the minimum between outNode's output channels and inNode's input channels).

Remarks
If outNode & inNode are not yet aliased, an alias for them will be created.

◆ connectBuffer() [2/2]

void Ogre::CompositorWorkspaceDef::connectBuffer ( IdString  outNode,
uint32  outChannel,
IdString  inNode,
uint32  inChannel 
)

Connects outNode's output buffer channel to inNode's input buffer channel.

Remarks
This mapping will later be used to know how connections should be done when instantiating. @See CompositorNode::connectBufferTo If outNode & inNode are not yet aliased, an alias for them will be created.

◆ connectExternal()

void Ogre::CompositorWorkspaceDef::connectExternal ( uint32  externalIdx,
IdString  inNode,
uint32  inChannel 
)

Connects the (probably "final") node by passing the RenderWindow in the given input channel.

Remarks
See also
connect inNode is not yet aliased, an implicit alias will be created.

◆ connectExternalBuffer()

void Ogre::CompositorWorkspaceDef::connectExternalBuffer ( uint32  externalBufferIdx,
IdString  inNode,
uint32  inChannel 
)

Connects an external buffer to the given input channel.

Remarks
If inNode is not yet aliased, an implicit alias will be created.

◆ createBuffer()

static UavBufferPacked * Ogre::TextureDefinitionBase::createBuffer ( const BufferDefinition bufferDef,
const RenderTarget finalTarget,
VaoManager vaoManager 
)
staticinherited

◆ createBuffers()

static void Ogre::TextureDefinitionBase::createBuffers ( const BufferDefinitionVec bufferDefs,
CompositorNamedBufferVec inOutBufContainer,
const RenderTarget 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 RenderTarget finalTarget,
RenderSystem renderSys 
)
staticinherited

◆ createTextures()

static void Ogre::TextureDefinitionBase::createTextures ( const TextureDefinitionVec textureDefs,
CompositorChannelVec inOutTexContainer,
IdType  id,
const RenderTarget 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.

◆ destroyTextures()

static void Ogre::TextureDefinitionBase::destroyTextures ( CompositorChannelVec inOutTexContainer,
RenderSystem renderSys 
)
staticinherited

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)

CompositorChannelVec inOutTexContainer,
const RenderTarget finalTarget,
RenderSystem renderSys,
const CompositorNodeVec connectedNodes,
const CompositorPassVec passes 
)
staticinherited

Destroys & recreates only the textures 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)

passesArray of Compositor Passes which may contain the texture being recreated When the pointer is null, we don't iterate through it.

◆ removeBuffer()

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

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

◆ removeNodeAlias()

void Ogre::CompositorWorkspaceDef::removeNodeAlias ( IdString  alias)

Removes a particular Node.

All of its connections to other node are also removed, which may leave other nodes with its inputs in an incomplete state.

◆ removeTexture()

virtual void Ogre::TextureDefinitionBase::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
nameName of the texture to remove.

Reimplemented in Ogre::CompositorNodeDef.

◆ 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()

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
numPassesThe number of texture definitions expected to contain.

◆ setNumLocalTextureDefinitions()

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