Chapter 427: JoinNode

Core Idea

This module is part of the TSL core and usually not used in app level code. It represents a join operation during the shader generation process. For example in can compose/join two single floats into a vec2 type.

Key Concepts

• nodes : Array.<Node>: An array of nodes that should be joined.

Reference Tables

Constructor

Signature
new JoinNode( nodes : Array.<Node>, nodeType : string )

Properties

Property	Description
.nodes : Array.<Node>	An array of nodes that should be joined.

Methods

Method	Description
.generateNodeType( builder : NodeBuilder ) : string	This method is overwritten since the node type must be inferred from the joined data length if not explicitly defined.

Key Takeaways

1. JoinNode extends: EventDispatcher → Node → TempNode
2. Most relevant properties: nodes.
3. Key methods: generateNodeType.
