bind() [3/3]

void MayaFlux::Nodes::Network::MeshFieldOperator::bind	(	uint32_t	slot_index,
		FieldTarget	target,
		Kinesis::VectorField	field
	)

Bind a VectorField to a slot.

Parameters

slot_index	Target slot index.
target	Vertex attribute to drive (POSITION, COLOR, NORMAL, TANGENT).
field	VectorField: glm::vec3 -> glm::vec3.

Creates a FieldOperator for the slot if one does not yet exist. The FieldOperator is initialised from the slot's current vertex data. Subsequent binds on the same slot append fields to the existing operator.
