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.<Node, function()>, 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.
