Sean,
The 3d network seems to be working much better now, thanks!
An occasional exception that pops up now (maybe 1 in 10 runs), is


java.lang.IndexOutOfBoundsException: Index: 22, Size: 22

I'm not sure if this is related to the recent changes to
NetworkPortrayal3D.java, but I thought I would make you aware of the
issue.

Subject: Re: 3d Edge Portrayal Problem

Okay, we've stomped the bug.  It's out on CVS but there's a new  
function that you'll need to call from your setupPortrayals() (or  
start() or load()) method: display.destroySceneGraph().  See any of  
the 3D app example code to see where it goes.  Also the tutorials.

Note that this will work fine with CylinderEdgePortrayal3D and  
SimpleEdgePortrayal3D, but ConeEdgePortrayal3D and  
ArrowEdgePortryal3D still need a tiny bit of work, which should be  
out on CVS by end of tomorrow my guess is.
