OverrideContextNode
A specialized context node designed to override specific target nodes within a node sub-graph or flow. This allows replacing specific inputs (e.g., normal and position vectors) dynamically during compilation for a specific flow node, without having to reconstruct or duplicate the source nodes.
Code Example
// Method chaining example:
node.overrideNode( positionLocal, () => positionLocal.add( vec3( 1, 0, 0 ) ) );
// Context assignment example:
material.contextNode = overrideNode( positionLocal, () => positionLocal.add( vec3( 1, 0, 0 ) ) );
Constructor
new OverrideContextNode( overrideNodes : Map., flowNode : Node | null )
Constructs a new override context node.
overrideNodes
A map mapping target nodes to their respective override callback functions.
flowNode
The node whose context should be modified.
Default is null.
Properties
.isOverrideContextNode : boolean (readonly)
This flag can be used for type testing.
Default is true.
.type : string (readonly)
Returns the type of the node.
Methods
.getFlowContextData() : Object
Gathers the context data from all parent context nodes by traversing the hierarchy, merging the overrideNodes maps from all encountered OverrideContextNode instances.
Overrides: ContextNode#getFlowContextData
Returns: The gathered context data, containing the merged overrideNodes map.
