JOGL 2 support for Ardor3D, JMonkeyEngine 3, jzy3d and NiftyGUI

Thanks. I will port the unified renderer to JOGL 2. If they remove the JOGL backend from their repository, I will fork it like we did with LibGDX.

Personally I don't have the time (nor inclination to do it) but if some JOGL-knowledgable person feels like it the jMonekyEngine team sure could use some help in maintaining the JOGL-renderer in the upcoming 3.1 release

http://hub.jmonkeyengine.org/t/can-we-expect-jogl-as-an-official-render-option-in-jme/33555

I guess we should put the sample quoted in that thread in our wiki..

Are there any working ports for jME 3.1 alpha? I can't get JOGL to work with the jME master branch at the moment.

What's wrong exactly? It was working a few months ago. The unified renderer is missing but I thought that it was still possible to use the old renderer.

The JOGL jme renderer fails to start. For example I tried running the TestSafeCanvas app, using settings.setRenderer("JOGL"), and it threw the following exception:

I'll fix it tonight. Thanks for the feedback.

The regression is here:

There is the same bug in JoglAbstractDisplay.

Edit.: Just put this call in canvas.invoke(false, new GLRunnable() {  public boolean run(GLAutoDrawable glad) { /*HERE*/ }}); and it will work.

I tried applying this fix to JoglNewtAbstractDisplay and now there is no canvas made visible. The app starts without exception but nothing is shown. For reference here's what the updated code looks like:

        canvas.invoke(false, new GLRunnable() {
            public boolean run(GLAutoDrawable glad) {
                renderer.setMainFrameBufferSrgb(settings.getGammaCorrection());
                return true;
            }
        });

Thanks for testing. Please try to find the last working revision so that I can find which other change broke the JOGL renderer. It was working in May for sure.

It appears the app gets hung on the startCanvas(true) call. Caused by a wait() on createdLock in JoglContext which is never notified.

This may have been solved by in the next jogamp release
https://jogamp.org/bugzilla/show_bug.cgi?id=1161

we sould try verify if the current JogAmp 2.3.2-rc test build fixes this issue

I tried running the same app with startCanvas(false) and it throws the following exception:

Hi can you test using

built on 21-Aug-2015
this includes most of the fixes of:

including the
https://jogamp.org/bugzilla/show_bug.cgi?id=1161

Which version of JOGL do you use? Which canvases/windows/displays are still broken?

Thank you for your help, it's really welcome.

Edit.: Your very last error will be fixed when I implement the unified renderer, a fix hasn't been ported to the old style renderer.

I just tested with this version (using TestSafeCanvas app). When the app is started using the startCanvas(true), the result is the same with the JoglContext.waitFor(true) method never returning. However, if the app is started with JoglContext.waitFor(false), the canvas is now shown but the app still throws an exception and it seems frozen. Here's the exception thrown:

Which version of JOGL do you use? Which canvases/windows/displays are still broken?

Running with that latest JOGL build (but similar results with v2.3.1), JoglCanvas and JoglNewtCanvas are broken. I've done a couple random tests with the the JoglDisplay and JoglNewtDisplay and they seem to work, except with that TestInstanceNode app which produced the exception I posted earlier.

Please file a bugreport and include runtime version check and debug log
http://jogamp.org/wiki/index.php/Jogamp_Versioning_and_Releases#Runtime_Version_Check

you can create these logs that will tell us more about your system using:

wget http://jogamp.org/deployment/archive/master/gluegen_885-joal_611-jogl_1425-jocl_1074/archive/jogamp-all-platforms.7z
7z x jogamp-all-platforms.7z
cd jogamp-all-platforms
sh etc/test.sh
sh etc/test_dbg.sh



Cheers

Hi can you test using
http://jogamp.org/deployment/archive/master/gluegen_885-joal_611-jogl_1425-jocl_1074/

I just tested with this version (using TestSafeCanvas app). When the app is started using the startCanvas(true), the result is the same with the JoglContext.waitFor(true) method never returning. However, if the app is started with JoglContext.waitFor(false), the canvas is now shown but the app still throws an exception and it seems frozen. Here's the exception thrown:

It should work a bit better now. The canvases are still broken, I think that the system listener isn't set during the initialization, that's why you get a NullPointerException. I'm going to fix this bug as soon as possible.

So you're working on this? No need for that bug report?
