public class AxisBehavior
extends javax.media.j3d.Behavior

Behavior class to extract the rotation component of the view platform transform, and set the axis transform to the inverse of that rotation. The axis should be added as a child of the platform geometry. Note that this behavior must run after the view platform behavior.
