Chapter 95: VolumeNodeMaterial

Core Idea

Volume node material.

Key Concepts

• isVolumeNodeMaterial : boolean (readonly): This flag can be used for type testing.
• offsetNode : Node.<float>: Offsets the distance a ray has been traveled through a volume. Can be used to implement dithering to reduce banding.
• scatteringNode : function | FunctionNode.<vec4>: Node used for scattering calculations.
• steps : number: Number of steps used for raymarching.

Constructor

Signature
new VolumeNodeMaterial( parameters : Object )

Properties

Property	Description
.isVolumeNodeMaterial : boolean (readonly)	This flag can be used for type testing.
.offsetNode : Node.<float>	Offsets the distance a ray has been traveled through a volume. Can be used to implement dithering to reduce banding.
`.scatteringNode : function	FunctionNode.<vec4>`
.steps : number	Number of steps used for raymarching.

Key Takeaways

1. VolumeNodeMaterial extends: EventDispatcher → Material → NodeMaterial
2. Most relevant properties: isVolumeNodeMaterial, offsetNode, scatteringNode, steps.
