extract_network_gpu_data()

MAYAFLUX_API NetworkGpuData MayaFlux::Buffers::extract_network_gpu_data	(	const std::shared_ptr< Nodes::Network::NodeNetwork > &	network,
		std::string_view	name
	)

Extract GPU geometry data from a NodeNetwork via its GraphicsOperator.

Returns empty NetworkGpuData if the network has no operator, the operator is not a GraphicsOperator, or the operator has no vertex data this frame. Logs at TRACE level for empty/missing data, WARN for operator type mismatch.

Parameters

network	Network to extract from
name	Logical name used in log messages

Returns

Populated NetworkGpuData, or empty if not available
