WorkgroupInfoNode

A node allowing the user to create a 'workgroup' scoped buffer within the context of a compute shader. Typically, workgroup scoped buffers are created to hold data that is transferred from a global storage scope into a local workgroup scope. For invocations within a workgroup, data access speeds on 'workgroup' scoped buffers can be significantly faster than similar access operations on globally accessible storage buffers.

This node can only be used with a WebGPU backend.

Constructor

new WorkgroupInfoNode( scope : string, bufferType : string, bufferCount : number )

Constructs a new buffer scoped to type scope.

scope

TODO.

bufferType

The data type of a 'workgroup' scoped buffer element.

bufferCount

The number of elements in the buffer.

Default is 0.

Properties

.bufferCount : number

The buffer count.

Default is 0.

.bufferType : string

The buffer type.

.elementType : string

The data type of the array buffer.

.isWorkgroupInfoNode : boolean (readonly)

This flag can be used for type testing.

Default is true.

.name : string

The name of the workgroup scoped buffer.

Default is ''.

Overrides: Node#name

.scope : string

TODO.

Methods

.element( indexNode : IndexNode ) : WorkgroupInfoElementNode

This method can be used to access elements via an index node.

indexNode

indexNode.

Returns: A reference to an element.

.getElementType() : string

The data type of the array buffer.

Overrides: Node#getElementType
Returns: The element type.

.getInputType( builder : NodeBuilder ) : string

Overwrites the default implementation since the input type is inferred from the scope.

builder

The current node builder.

Returns: The input type.

.label( name : string ) : WorkgroupInfoNode

Sets the name/label of this node.

name

The name to set.

Deprecated: Yes
Returns: A reference to this node.

.setName( name : string ) : WorkgroupInfoNode

Sets the name of this node.

name

The name to set.

Returns: A reference to this node.

.setScope( scope : string ) : WorkgroupInfoNode

Sets the scope of this node.

scope

The scope to set.

Returns: A reference to this node.
