>From your code snippet it doesn't look like you have attached the ViewPlatform
to anything. Since your ViewBranch class extends BranchGroup you should be
able to simply call addChild() with your ViewPlatform instance and then add
your ViewBranch instance to a Locale (but you'll probably want to add a
TransformGroup above the ViewPlatform so you can manipulate the view position
and orientation).
For an example of something very similiar to what you're doing take a look at
the source code for com.sun.j3d.utils.universe.ViewingPlatform.
