topology_runs()

std::vector< DrawRun > MayaFlux::Nodes::Network::TopologyOperator::topology_runs ( ) const

overridevirtual

Coalesces adjacent topology graphs sharing a concatenable topology into one run.

Strip and fan graphs are always reported separately.

Reimplemented from MayaFlux::Nodes::Network::GraphicsOperator.
