Scene Graph Superstructure Objects
• A VirtualUniverse object
– Consists of a list of Local objects that contain a collection of
scene graph nodes
– An application will typically need only one VirtualUniverse
• A Locale object
– Acts as a container for a collection of sub-graphs of the
scene graph that are rooted by a BranchGroup node
– Defines a location within the virtual universe using highresolution
coordinates (HiResCoord) to specify its position
