@ Steve
Which approach are you referring too ? The lwjglfx solution or this
transparency background solution ?

The lwjglfx I am assuming here since its drawing out to an image and back
in again. But if your speaking about my transparency issue I solved, I
didn't realize it was sending out to an image and back again. Could you
please elaborate as to which solution your speaking about ?

This solution is cool, but it draws to an image, sucks out the bits and
then converts that to an FX image.  This is a good approach because it uses
API and does not rely on any internals of FX. Hopefully it is fast enough
for you.

Yea the OpenGL comes with your graphics drivers for your video card. So
your correct that it doesn't ship with JavaFX. What I have been going on
about is trying to find a way to use JavaFX with LWJGL. In case you are
unaware, LWJGL just means "Light Weight Java OpenGL" and its a wrapper for
the OpenGL API. It's an alternative to JOGL.

On another note, as I did a search, Thanks to Tom showing me that link I
examined that code and I found something of interest in the JOGL code
interface..  well it lead me to a google search, and viola..  LWJGL with
JavaFX. :)

LINK :

So just wanted to post the link here and say thanks for all of your help.

  JavaFX does not ship OpenGL binaries on windows you have to build it your

own.

Please note:
a) if there are people who manage to write a prism pipeline on jogl why
should you not be able to do the same with lwjgl?
b) the talk i mentionned from felipe and steve show how to get access to
the native OpenGL context and there from you can use any API you like
can't
remember which one they used

Thanks, but as I mentioned in my original post, I don't like JOGL. It
doesn't work with my setup. I use LWJGL because its only about the
OpenGL
and not other libraries, and its an easy API wrapper to use. There are

many

many reason I hate JOGL.. but this thread is not about hating on JOGL,

its

about finding a way to use LWJGL with JavaFX2+.

Also, Win32 API calls can use both DirectX and OpenGL APIs. And it

doesn't

matter what Windows OS you're using. I have tested this out from Windows

XP

all the way to Windows 7 - 32/64 Bit with no problem.

Search for it on parleys - this does not help you on Win32 which uses
directx instead of javafx. BTW there are people doing a JOGL pipeline

Yea its a shame that using JavaFX as an option along with OpenGL
wasn't
even thought of to begin with. I don't understand why they limit you

like

they do. Them trying to recreate the wheel and make their own version

of

a

3D interface is just plain stupid if it can't run low level. I can see

2D

games and applications with a LOT of usage for JavaFX and its 2D

graphics

API. But True 3D needs low level other wise its a waste of time.

Well, thanks for the replies. Guess I'll have to stick with using
other
sources for my GUI. It's just that I like JavaFX version of its GUI

because

it is so simple to use. But not worth it if you can't use it for the

reason

that we the people need it for. Like in my case, game dev.

Cheers.

  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.

Can you please explain what True 3D means in terms of Low Level API
?
Because with LWJGL I can use Low Level API to talk directly to my

Video

Card. As a game dev, I need every ounce of umph from the card I can

get,

and using a browser or any other kind of wrapper hasn't proven very

efficient. I love LWJGL because of its simplicity. Anything extra I

need, I

am allowed to make on my own. Example, my own Game Engine.

And that is where I am at. So if your speaking about Nodes, I am

aware

there is a hierarchy to the JavaFX2 when setting up the GUI, but that

is

the only thing I knew existed. Could you please elaborate what makes

JavaFX8 a True 3D Low Level interface API ? Because from the

presentation,

you have to go through two layers before you have to get to the

OpenGL

layer. Where as if I can use LWJGL, I can skip a level.

If I am misinformed on something, please, explain. Because I am new

to

JavaFX.

This would allow to render JavaFx content in an external OpenGL

I

this. I

saw a

both

prism,

I

can't find info on how to talk to opengl and I can't find any

anywhere. So I am posting here to see what I can find. I do NOT

JOGL.

I prefer LWJGL. So far, the only thing related to 3D with regards

to

JavaFX

is the very resource intensive Canvas3D, which I can't stand. Any

ideas ?

Is it not implemented yet and its on its way ? I'm trying to find

any

info

I can about this. If there is nothing for LWJGL, then I can't use

JavaFX.

Thanks.
