BaseTransformationController

public abstract class BaseTransformationController

Known Direct Subclasses RotationController, ScaleController, TranslationController RotationController Manipulates the rotation of a BaseTransformableNode using a TwistGestureRecognizer.  ScaleController Manipulates the Scale of a BaseTransformableNode using a Pinch PinchGestureRecognizer.  TranslationController Manipulates the position of a BaseTransformableNode using a DragGestureRecognizer.

Manipulates the transform properties (i.e. scale/rotation/translation) of a BaseTransformableNode by responding to Gestures via a BaseGestureRecognizer.

Example's include, changing the TransformableNode's Scale based on a Pinch Gesture.
