build_cluster_ids()

std::vector< uint32_t > MayaFlux::Nodes::Network::AssemblyOperator::build_cluster_ids ( ) const

overridevirtual

One cluster id per item; coincides with get_vertex_count() since items carry no interpolation step of their own.

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