Multiple Views - Interactive Web-Based Virtual Reality with Java 3D - page 261

Figure 22 shows the view branch of the scene graph, the important code segment, the
result and the display configuration in creating a portal view of a virtual world using three
monitor panels with a tilting angle of 45 degrees.
As shown, each panel of the system has its ViewPlatform and View objects. The
TransformGroups of these panels come under a parent TransformGroup associated with
