IndexNode

This class represents shader indices of different types. The following predefined node objects cover frequent use cases:

  • vertexIndex: The index of a vertex within a mesh.
  • instanceIndex: The index of either a mesh instance or an invocation of a compute shader.
  • drawIndex: The index of a draw call.
  • invocationLocalIndex: The index of a compute invocation within the scope of a workgroup load.
  • invocationSubgroupIndex: The index of a compute invocation within the scope of a subgroup.
  • subgroupIndex: The index of a compute invocation's subgroup within its workgroup.

Constructor

new IndexNode( scope : 'vertex' | 'instance' | 'subgroup' | 'invocationLocal' | 'invocationGlobal' | 'invocationSubgroup' | 'draw' )

Constructs a new index node.

scope

The scope of the index node.

Properties

.isIndexNode : boolean (readonly)

This flag can be used for type testing.

Default is true.

.scope : string
