All I can say, is that you appear to be one of a very few (or a one
project) that has noted all these problems. Maybe the project you're
working on isn't suited to Java3D, maybe the way you're thinking about
it isn't suited to Java3D. Either way, you're not talking about a
general case here..

Just want to tell you that our old Full Sail Open Flight Loader link

I don't think JOGL is aimed at 'us'. It's aimed at the games
companies as a 'not too different way of programming than
the C/C++ wrapper over OpenGL that you're already using'.
My guess is that Sun thinks Java 3D and its supporters can

IL-2 / Forgotten Battles uses Java for more than just a "scripting
language". Based on the fact that you can swap the JVM for a different
version of JVM and the performance / frame rate changes indicates that
Java *is* running during real time playing / flying. I do believe Oleg
Maddox mentioned
Unfortunately IL2, although it uses Java as a scripting language, uses a C++ 3D
engine. I have seen this rumour around the place for a while and it is just incorrect.
I think the faq on the IL2 site corrects this.

If you load an OBJ-file you usualy get a shape3D object. If you want to get
the geometry of it you need to set the capabilities
(Shape3D.ALLOW_GEOMETRY_READ, ..._WRITE)
I think then you can do what you want with the geometry.
