If you used NewtCanvasJFX, the interaction with OpenJFX / JavaFX would be easier and would use less intermediary classes.

Please can you provide a simple reproducer with Java3D if you think you can't reproduce it without Java3D?

I vaguely remember that Java3D Canvas3D and JCanvas3D do NOT extend GLCanvas and GLJPanel.
