How to force OpenGL 3+ with JOGL?

Development
1

@gouessej , and others who can help

I give a try to jogl backend. In my deferred renderer I use shader in GLSL 1.5. But on mac os x (macbook pro) to be able to use OpenGL 3+ we have to force “3.2 core” profile (without compatibility, see OpenGL 3.2 on Mac OS X trouble. jme 3.1 from github).

With LWJGL I used the following line :

settings.setRenderer(AppSettings.LWJGL_OPENGL3)

How to do this with JOGL ?

with

settings.setRenderer("JOGL")
settings.setAudioRenderer("JOAL")

I got the following error (the mac stay on OpenGL 2.1 and doesn’t swith to the OpenGL 4.1 card) :

Hi

I advise you to read this document to understand how the OpenGL profiles are managed in JOGL. It will probably change a little bit to support Vulkan.

You can use those methods to pick the most capable GLProfile or a particular one:
http://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/com/jogamp/opengl/GLProfile.html#getMaxProgrammable(boolean)
http://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/com/jogamp/opengl/GLProfile.html#get(java.lang.String)
http://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/com/jogamp/opengl/GLProfile.html#GL3

Modify this part of the code:
https://github.com/jMonkeyEngine/jmonkeyengine/blob/master/jme3-jogl/src/main/java/com/jme3/system/jogl/JoglAbstractDisplay.java#L85
https://github.com/jMonkeyEngine/jmonkeyengine/blob/master/jme3-jogl/src/main/java/com/jme3/system/jogl/JoglNewtAbstractDisplay.java#L79

Only JogAmp’s Ardor3D Continuation benefits of an easy way of customizing the OpenGL profile picked by the engine yet.

3

I’ll modify the code once for all as nobody except me really needs getMaxFixedFunc(true).

4

Hi, thanks for the info.
But I don’t want to pick/get the profile. I want to force the profile to use when I create the GLContext.
Macbook as dual OpenGL 2.1 (default), OpenGL 4.x (on demand/force).

Sorry, if I misunderstood your answer.

5

It think it is

GLProfile.getMaxProgrammableCore(true)

or:

GLProfile.get(GLProfile.GL3)
6

You probably misunderstood my answer. You have to create the GLCapabilities object with the right OpenGL profile and it will pick OpenGL 3.2 as you wish.

Don’t worry, I’ll make the change by myself when I’m at home. I’ll have to provide two constants and to test the settings before creating the GLCapabilities instance. You’ll have to call settings.setRenderer(AppSettings.JOGL_OPENGL_FORWARD_COMPATIBLE) to force OpenGL 3.2 or settings.setRenderer(AppSettings.JOGL_OPENGL_BACKWARD_COMPATIBLE) to use OpenGL 2.1.

Is it ok for you?

7

Thanks, it’s Ok for me, I’ll test tomorrow or when you’ll ping me. (I’m in France)

tbh, I try jogl to see if it can help me to fix an opengl crash I have only on macosx + lwjgl. And because I would like to try jogl’s multi-monitor support.

8

Lwjgl3?

9

no LWJGL 2 (I’ve got the error 1280 :wink: ), LWJGL3 is too young/WIP IMHO

10

If you find a way of making a virtual screen with several monitors with GLFW, let me know:
http://www.glfw.org/docs/latest/monitor.html
http://www.glfw.org/docs/latest/group__monitor.html

I’m sorry, I don’t want to hurt anybody but I loose my motivation when some developers repeatedly suggest to use another backend each time there is obviously an excellent test case for the JogAmp APIs. I encourage you to prove me that what I do is useless, please quote some documentation, show me that you are already able to use exactly the same windowing system in desktop environments and under Android without JogAmp.

11

That was a question to david, if he gets the error with the lwjgl3 backend or with the lwjgl2 one. Sorry if i was unclear

[OT] I test my current jogl code (available on github) on my Linux, and I’got a jvm crash.

Please use JOGL 2.3.2 instead of JOGL 2.3.1 and reproduce your crash on a tiny test case. You can use our online test, for example this one:
http://jogamp.org/deployment/jogamp-current/jogl-application-version.jnlp

Rather post your question specific to JOGL on our official forum, not here.

14

I have implemented what you asked. Fill a bug report against JOGL if your crash persists but follow our guidelines:
http://jogamp.org/wiki/index.php/Jogl_FAQ#Bugreports_.26_Testing

15

Thanks, I’m coding a tiny jme3_jogl project to test.

16

I create a simple jme application at : GitHub - davidB/sandbox_jme3_jogl: experiment jme3 with jogl backend

  • with jogl 2.3.1 I reproduce the crash.
  • with forced jogl 2.3.2, no longer crash (hourra thanks). I saw your commits to used jogl 2.3.2 for next jme3-3.1.0-SNAPSHOT (then I’ll remove the forced version).

So I’ll not open the bug on joamp’s buzilla.

The sample project can be used by other jme user (to test jogl or report bugs,I enable debug-all system property)

17

Please can you tell me which graphics card you use and which driver? It would be useful for me in case someone else gets a crash with the same hardware with an obsolete version of JOGL.

A contributor has found a regression in the support of fullscreen mode with several monitors, it happens only under Windows with JOGL 2.3.2. We asked him to write a bug report but I’m not sure he did. I’ll have to fix this bug before improving the support of multiple monitors in another engine. After that, I’ll port my code from this engine to JMonkeyEngine. The remaining problem is that you’ll probably have to use some JOGL code as there is not yet any API to abstract the management of screens and monitors. Note that this feature only works with NEWT, not with AWT.

On linux:

Tomorrow I could swith to windows 10 if you need.

Thank you. You should modify your test to use the correct string to pass to AppSettings.setRenderer(), shouldn’t you?

Good night.
