Chapter 229: Storage3DTexture

Core Idea

This special type of texture is intended for compute shaders. It can be used to compute the data of a texture with a compute shader.

Note: This type of texture can only be used with WebGPURenderer and a WebGPU backend.

Key Concepts

• image : Object: The image object which just represents the texture's dimension.
• is3DTexture : boolean: Indicates whether this texture is a 3D texture.
• isStorageTexture : boolean (readonly): This flag can be used for type testing.
• magFilter : number: The default magFilter for storage textures is THREE.LinearFilter.
• minFilter : number: The default minFilter for storage textures is THREE.LinearFilter.
• wrapR : number: This defines how the texture is wrapped in the depth direction and corresponds to W in UVW mapping.

Constructor

Signature
new Storage3DTexture( width : number, height : number, depth : number )

Properties

Property	Description
.image : Object	The image object which just represents the texture's dimension.
.is3DTexture : boolean	Indicates whether this texture is a 3D texture.
.isStorageTexture : boolean (readonly)	This flag can be used for type testing.
.magFilter : number	The default magFilter for storage textures is THREE.LinearFilter.
.minFilter : number	The default minFilter for storage textures is THREE.LinearFilter.
.wrapR : number	This defines how the texture is wrapped in the depth direction and corresponds to W in UVW mapping.

Methods

Method	Description
.setSize( width : number, height : number, depth : number )	Sets the size of the storage 3d texture.

Key Takeaways

1. Storage3DTexture extends: EventDispatcher → Texture
2. Most relevant properties: image, is3DTexture, isStorageTexture, magFilter.
3. Key methods: setSize.
