It is not possible to combine JavaFX and OpenGL as it is right now. This was discussed on this mailing list some time before as a _possible_ future addition, but I’d be very surprised if Oracle actually chose to implement this.
Starting with JavaFX 8 there is indeed some kind of „3D support“ but the 3D API allows only for the most basic operations. It is still completely scene graph based and you have to live with all restrictions that JavaFX imposes on you. Not wanting to say that the 3D API is completely useless, but I’m afraid that even WPF is more flexible when it comes to 3D than JavaFX is. For example: As far as I know you can not even change the shading model from GL_SMOOTH to GL_FLAT. You could work around that by setting the normals yourself though (Same for WPF). Also render quality is bad when you render an instance of Text in 3D and scale it down for example. At least it was when I tried that last time (few months ago). Again, not to say that one can’t work with JavaFX’s 3D API, but it’s not raw OpenGL either. As far as I know the JavaFX team wants to be able to let the user use his own OpenGL context and let JavaFX render on top of that or add the possibility to ask JavaFX for the underlying context and mess with that but this is not even officially planned or included on any roadmap (AFAIK) so we can only keep our fingers crossed for that to happen. Like you I would absolutely LOVE to use JavaFX as a GUI on top of my OpenGL games.
