Chapter 462: ReflectorNode

Core Idea

This node can be used to implement mirror-like flat reflective surfaces.

Key Concepts

• reflector : ReflectorBaseNode: A reference to the internal reflector node.
• target : Object3D: A reference to 3D object the reflector is linked to.

Code Examples

const groundReflector = reflector();
material.colorNode = groundReflector;
const plane = new Mesh( geometry, material );
plane.add( groundReflector.target );

• What it demonstrates: Typical usage of ReflectorNode.

Reference Tables

Constructor

Signature
new ReflectorNode( parameters : Object )

Properties

Property	Description
.reflector : ReflectorBaseNode	A reference to the internal reflector node.
.target : Object3D	A reference to 3D object the reflector is linked to.

Methods

Method	Description
.dispose()	Frees internal resources. Should be called when the node is no longer in use.
.getDepthNode() : Node	Returns a node representing the mirror's depth. That can be used to implement more advanced reflection effects like distance attenuation.

Key Takeaways

1. ReflectorNode extends: EventDispatcher → Node → InputNode → UniformNode → TextureNode
2. Most relevant properties: reflector, target.
3. Key methods: dispose, getDepthNode.
