bind() [4/4]

void MayaFlux::Portal::Forma::Bridge::bind	(	uint32_t	id,
		std::shared_ptr< Nodes::Node >	node,
		std::function< float(double)>	project = {}
	)

Drive element value from a Node's output each frame.

Spawns a GraphicsRoutine that reads node->get_last_output() every tick, applies project, and writes into the element's MappedState. Node must be processed externally (EXTERNAL mode read). Replaces any existing inbound binding on this element.

Parameters

id	Element id (from Layer::add / Mapped::element.id).
node	Node to read from.
project	Optional double -> float projection. Identity if empty.
