std::shared_ptr< FieldOperator > MayaFlux::Nodes::Network::MeshFieldOperator::get_or_create ( MeshSlot &  slot, uint32_t  slot_index  )

private

Return an existing FieldOperator for the slot, or create and initialise one from the slot's current vertex data.

Parameters

slot	Slot whose FieldOperator to retrieve or create.
slot_index	Slot index (key into m_field_ops).

Returns

Pointer to the (possibly new) FieldOperator.
