Public Methods

Method	Description
CompileOutputOperation ( CompositeTargetOperation finalState ) : void	Compile the final (output) operation. This is done seperately because this is combined with the input in chained filters.
CompileTargetOperations ( List compiledState ) : void	Recursively collect target states (except for final Pass).
CompositorInstance ( CompositionTechnique technique, Axiom.Graphics.CompositorChain chain ) : System
CreateResources ( bool forResizeOnly ) : void	Create local rendertextures and other resources. Builds mLocalTextures.
FreeResources ( bool forResizeOnly, bool clearReservedTextures ) : void	Destroy local rendertextures and other resources.
GetTextureInstance ( string name ) : Axiom.Core.Texture	Get the instance for a local texture. It is only valid to call this when local textures have been loaded, which in practice means that the compositor instance is active. Calling it at other times will cause an exception. Note that since textures are cleaned up aggressively, this name is not guaranteed to stay the same if you disable and renable the compositor instance.
GetTextureInstance ( string name, int mrtIndex ) : Axiom.Core.Texture	Get the instance for a local texture. It is only valid to call this when local textures have been loaded, which in practice means that the compositor instance is active. Calling it at other times will cause an exception. Note that since textures are cleaned up aggressively, this name is not guaranteed to stay the same if you disable and renable the compositor instance.
OnMaterialRender ( CompositorInstanceMaterialEventArgs args ) : void	Notify listeners of a material render.
OnMaterialSetup ( CompositorInstanceMaterialEventArgs args ) : void	Notify listeners of a material compilation.
OnResourceCreated ( CompositorInstanceResourceEventArgs args ) : void	Notify listeners of a material render.

Protected Methods

Method	Description
CollectPasses ( CompositeTargetOperation finalState, CompositionTargetPass target ) : void	Collect rendering passes. Here, passes are converted into render target operations and queued with queueRenderSystemOp.
CreateLocalMaterial ( string name ) : Material	Create a local dummy material with one technique but no passes. The material is detached from the Material Manager to make sure it is destroyed when going out of scope.
QueueRenderSystemOp ( CompositeTargetOperation finalState, CompositeRenderSystemOperation op ) : void	Queue a render system operation.
dispose ( bool disposeManagedResources ) : void

Private Methods

Method	Description
DeriveTextureRenderTargetOptions ( string texname, bool &hwGammaWrite, int &fsaa, string &fsaaHint ) : void	Search for options like AA and hardware gamma which we may want to inherit from the main render target to which we're attached.
GetMrtTextureLocalName ( String baseName, int attachment ) : String

Method Details

CollectPasses() protected method

Collect rendering passes. Here, passes are converted into render target operations and queued with queueRenderSystemOp.

protected CollectPasses ( CompositeTargetOperation finalState, CompositionTargetPass target ) : void
finalState	CompositeTargetOperation
target	CompositionTargetPass
return	void

CompileOutputOperation() public method

Compile the final (output) operation. This is done seperately because this is combined with the input in chained filters.

public CompileOutputOperation ( CompositeTargetOperation finalState ) : void
finalState	CompositeTargetOperation
return	void

CompileTargetOperations() public method

Recursively collect target states (except for final Pass).

public CompileTargetOperations ( List compiledState ) : void
compiledState	List	This vector will contain a list of TargetOperation objects
return	void

CompositorInstance() public method

public CompositorInstance ( CompositionTechnique technique, Axiom.Graphics.CompositorChain chain ) : System
technique	CompositionTechnique
chain	Axiom.Graphics.CompositorChain
return	System

CreateLocalMaterial() protected method

Create a local dummy material with one technique but no passes. The material is detached from the Material Manager to make sure it is destroyed when going out of scope.

protected CreateLocalMaterial ( string name ) : Material
name	string
return	Material

CreateResources() public method

Create local rendertextures and other resources. Builds mLocalTextures.

public CreateResources ( bool forResizeOnly ) : void

public FreeResources ( bool forResizeOnly, bool clearReservedTextures ) : void
forResizeOnly	bool
clearReservedTextures	bool
return	void

GetTextureInstance() public method

Get the instance for a local texture.

It is only valid to call this when local textures have been loaded, which in practice means that the compositor instance is active. Calling it at other times will cause an exception. Note that since textures are cleaned up aggressively, this name is not guaranteed to stay the same if you disable and renable the compositor instance.

return	Axiom.Core.Texture

GetTextureInstance() public method

Get the instance for a local texture.
