By the way, I am working on a port of Jzy3D (a Java 3D scientific graphics library) to Qt. I have finished the majority of the work, and am now working on debugging and cleaning up memory leaks. It will probably be hosted on the Jzy3D web site and I will make announcements here. See the attached screen shots for what can be done with it. It will be released with the same license as Jzy3D.
