Hi All, Have been trying to understand the Java3D hierarchy.
As i understand, a locale provides a co-ordinate system to the universe. But it is stated that a universe can have multiple locales. I can understand that too to some extent. When we add a node we specify its position, geometry, etc with respect to the co-ordinate system provided by one of the locales in the universe. Is my understanding fine so far? Also: 1. Are we saying that a node can exist only with respect to one of the locales in the the universe?? 2. Can the viewing platform attached to one locale see the nodes added to other locales in the same universe?? 3. Shouldnt the design have been in such a way that the node is added to the universe directly specifying a reference to the locale in terms of which its position and geometry is given? Lastly, could someone spend sometime in describing briefly - when multiple locales are used. or at least point me to some resource that will clarify this for me.
