Chapter 437: MRTNode

Core Idea

This node can be used setup a MRT context for rendering. A typical MRT setup for post-processing is shown below:

The MRT output is defined as a dictionary.

blendModes : Object.<string, BlendMode>: A dictionary storing the blend modes for each output.
isMRTNode : boolean (readonly): This flag can be used for type testing.
outputNodes : Object.<string, Node>: A dictionary representing the MRT outputs. The key is the name of the output, the value the node which produces the output result.

const mrtNode = mrt( {
  output: output,
  normal: normalView
} ) ;

Constructor

Signature
`new MRTNode( outputNodes : Object.<string, Node> )`

Properties

Property	Description
`.blendModes : Object.<string, BlendMode>`	A dictionary storing the blend modes for each output.
`.isMRTNode : boolean (readonly)`	This flag can be used for type testing.
`.outputNodes : Object.<string, Node>`	A dictionary representing the MRT outputs. The key is the name of the output, the value the node which produces the output result.

Methods

Method	Description
`.get( name : string ) : Node`	Returns the output node for the given name.
`.getBlendMode( name : string ) : BlendMode`	Returns the blend mode for the given output name.
`.has( name : string ) : NodeBuilder`	Returns `true` if the MRT node has an output with the given name.
`.merge( mrtNode : MRTNode ) : MRTNode`	Merges the outputs of the given MRT node with the outputs of this node.
`.setBlendMode( name : string, blend : BlendMode ) : MRTNode`	Sets the blend mode for the given output name.
