Pushing the valuator forwards gives the appearance of the virtual world increasing in size, while pushing the valuator backwards makes the virtual world appear to shrink. The X and Y values from the valuator should have a continuous range from -1.0 to +1.0, although the scale speed can be adjusted to compensate for a different range. <p> This listener will work in conjunction with a 6DOF sensor if supplied in the constructor. If <code>setTransformCenterSource</code> has been called with the value <code>HOTSPOT</code>, then scaling is about the 6DOF sensor's hotspot; otherwise, the scaling center is the value set by <code>setTransformCenter</code>.<P><P><DL><DT><B>See Also:</B><DD><A
