Right now it is not possible to reliably mix Java 3D and OpenGL in the
same window.
In theory it is possible, but not supported. You could get the native
window handle
through AWT, create your own OpenGL context, and tap into just the
right place in
the Canvas3D callbacks to get it to work. But it is very tricky.
Extensibility of this
nature is one of the features that we would like to add to Java 3D.

Dear all
Alan, thanks for the tip. Does the Java3D team onfirm Alan
statement
that OpenGL and Java3D cannot be mixed? It seems strange to me since I
thought Java3D was implemented in OpenGL in low level anyway (when
using
OpenGL distribution), therefore there should be some way to mix both,
however
that require some information from the Java3D team. Could we have this
info? Specifically, how to exchange drawing surface parameters between
Java3D and OpenGL as well as synchronization issues.
thanks
Yohan

You do not have this much freedom with Java3D. It expects to
rule the
world, so you cannot hand it a surface and expect to mix Java3D and
OpenGL commands. We are considering how to do this with our upcoming
open source scenegraph API(Aviatrix), but its not released yet.
Pershaps Xith3D could help, but I don't know if they are exposing this
level of access or not.
