The TransformSensor generates events containing any transformations of the descendant geometry in the global coordinate system.
The includeViewer field specifies if viewer position is used in TransformSensor fields calculations or not.
The translation_changed event is generated if the translation is changed.
The rotation_changed event is generated if the rotation is changed.
The center_changed event is generated if the center of transform is changed.
The scale_changed event is generated if the scale is changed.
The scaleOrientation_changed event is generated if the scaleOrientation is changed.
The transform_changed event is generated if the transform is changed.
