apply_one_to_one()

void MayaFlux::Nodes::Network::GraphicsOperator::apply_one_to_one ( std::string_view  param, const std::shared_ptr< NodeNetwork > &  source  )

overridevirtual

Apply ONE_TO_ONE parameter mapping.

Default implementation handles common graphics properties:

• "color": Per-point color
• "size": Per-point size (for point rendering)

Reimplemented from MayaFlux::Nodes::Network::NetworkOperator.

Reimplemented in MayaFlux::Nodes::Network::PhysicsOperator.
