[JAVA3D] Visible of VRML nodes not consistent

[Dean Keeler]

Hi,   I have an application that loads in a VRML file.  Whenever I manipulate the model by rotating it, zooming in on it, etc, the model starts hiding and showing different VRML nodes.  Some nodes that should show behind other nodes that are in the foreground are showing in front.  How can I keep this from happening?  Can someone please give me some suggestions?   Thanks for you time,   Dean
