public class Nexus
extends DNXObject
An Nexus is an object that manages the interaction of the user with a VRML scene. An nexus contains a root node instance specifying what is being managed (the scene itself is derivable from the NodeInstance, or from the Document), and a list of views (i.e. visible representations of the scene).
