StorageTextureNode

This special version of a texture node can be used to write data into a storage texture with a compute shader.

This node can only be used with a WebGPU backend.

Code Example

const storageTexture = new THREE.StorageTexture( width, height );
const computeTexture = Fn( ( { storageTexture } ) => {
	const posX = instanceIndex.mod( width );
	const posY = instanceIndex.div( width );
	const indexUV = uvec2( posX, posY );
	// generate RGB values
	const r = 1;
	const g = 1;
	const b = 1;
	textureStore( storageTexture, indexUV, vec4( r, g, b, 1 ) ).toWriteOnly();
} );
const computeNode = computeTexture( { storageTexture } ).compute( width * height );
renderer.computeAsync( computeNode );

Constructor

new StorageTextureNode( value : StorageTexture, uvNode : Node.<(vec2|vec3)>, storeNode : Node )

Constructs a new storage texture node.

value

The storage texture.
uvNode

The uv node.
storeNode

The value node that should be stored in the texture.

Default is null.

Properties

.access : string

The access type of the texture node.

Default is 'writeOnly'.

.isStorageTextureNode : boolean (readonly)

This flag can be used for type testing.

Default is true.

.mipLevel : number

The mip level to write to for storage textures.

Default is 0.

.storeNode : Node

The value node that should be stored in the texture.

Default is null.

Methods

.generate( builder : NodeBuilder, output : string ) : string

Generates the code snippet of the storage node. If no storeNode is defined, the texture node is generated as normal texture.

builder

The current node builder.
output

The current output.
Overrides: TextureNode#generate
Returns: The generated code snippet.

.generateStore( builder : NodeBuilder )

Generates the code snippet of the storage texture node.

builder

The current node builder.

.getInputType( builder : NodeBuilder ) : string

Overwrites the default implementation to return a fixed value 'storageTexture'.

builder

The current node builder.
Overrides: TextureNode#getInputType
Returns: The input type.

.setAccess( value : string ) : StorageTextureNode

Defines the node access.

value

The node access.
Returns: A reference to this node.

.setMipLevel( level : number ) : StorageTextureNode

Sets the mip level to write to.

level

The mip level.
Returns: A reference to this node.

.toReadOnly() : StorageTextureNode

Convenience method for configuring a read-only node access.

Returns: A reference to this node.

.toReadWrite() : StorageTextureNode

Convenience method for configuring a read/write node access.

Returns: A reference to this node.

.toWriteOnly() : StorageTextureNode

Convenience method for configuring a write-only node access.

Returns: A reference to this node.
