- Direct Known Subclasses:
- PickRotateBehavior, PickTranslateBehavior, PickZoomBehavior
- public abstract class PickMouseBehavior
- extends javax.media.j3d.Behavior
Base class that allows users to adding picking and mouse manipulation to
his scene graph (see PickDragBehavior for an example of how to extend
this base class). This class is useful for interactive apps.
