add_node()

void MayaFlux::Buffers::AggregateBindingsProcessor::add_node	(	const std::string &	aggregate_name,
		const std::shared_ptr< Nodes::Node > &	node,
		const std::shared_ptr< VKBuffer > &	target
	)

Add a node to a named aggregate.

Parameters

aggregate_name	Name of the aggregate group
node	Node to add
target	Target buffer for this aggregate

Nodes with the same aggregate_name are grouped together and uploaded to the same target buffer. Nodes are ordered by insertion.
