Chapter 430: Lut3DNode

Core Idea

A post processing node for color grading via lookup tables.

Key Concepts

• inputNode : Node: The node that represents the input of the effect.
• intensityNode : Node.<float>: Controls the intensity of the effect.
• lutNode : TextureNode: A texture node that represents the lookup table.
• size : UniformNode.<float>: The size of the lookup table.

Code Examples

import { lut3D } from 'three/addons/tsl/display/Lut3DNode.js';

• What it demonstrates: Typical usage of Lut3DNode.

Reference Tables

Constructor

Signature
new Lut3DNode( inputNode : Node, lutNode : TextureNode, size : number, intensityNode : Node.<float> )

Properties

Property	Description
.inputNode : Node	The node that represents the input of the effect.
.intensityNode : Node.<float>	Controls the intensity of the effect.
.lutNode : TextureNode	A texture node that represents the lookup table.
.size : UniformNode.<float>	The size of the lookup table.

Methods

Method	Description
.setup( builder : NodeBuilder ) : ShaderCallNodeInternal	This method is used to setup the effect's TSL code.

Key Takeaways

1. Lut3DNode extends: EventDispatcher → Node → TempNode
2. Most relevant properties: inputNode, intensityNode, lutNode, size.
3. Key methods: setup.
