A virtual universe consists of a set of Locale objects, each of which has a high-resolution position within the virtual universe. An application or applet may have more than one VirtualUniverse objects, but many applications will need only one. Virtual universes are separate entities in that no node object may exist in more than one virtual universe at any one time. Likewise, the objects in one virtual universe are not visible in, nor do they interact with objects in, any other virtual universe. <p> A VirtualUniverse object defines methods to enumerate its Locale objects and to remove them from the virtual universe.<P><P><DL><DT><B>See Also:</B><DD><A HREF="../../../javax/media/j3d/Locale.html"><CODE>Locale</CODE></A></DL><HR><P><!-- ======== NESTED CLASS
