bind_network()

void MayaFlux::Buffers::NetworkGeometryProcessor::bind_network	(	const std::string &	name,
		const std::shared_ptr< Nodes::Network::NodeNetwork > &	network,
		const std::shared_ptr< VKBuffer > &	vertex_buffer
	)

Bind a network to a GPU vertex buffer.

Parameters

name	Logical name for this binding
network	NodeNetwork to aggregate geometry from
vertex_buffer	GPU vertex buffer to upload to

If vertex_buffer is device-local, a staging buffer is automatically created.
