| The Operator object represents an operator in the scene graph. Objects or Parameters are connected to the operator via InputPorts or OutputPorts. These ports are organized into port groups. The port groups contain all ports that will be connected to parts of the selected or picked object. For example, when the Twist_op operator is applied to a selected object the operator has ports that read from the object's local KinematicState and Geometry and write to the result object's geometry.
