Exception in thread "main" com.jogamp.opengl.GLException

I am getting this error on starting RoboViz monitor using the command: ./roboviz.sh

Screenshot:

I have Java 1.8 and also turned off shadow and high graphics features from config.txt file but still getting the same error.

Any help please?

What version of RoboViz are you using? It's at least not the latest version from what I can see in the stack trace. I suggest upgrading to the latest version (1.8.0). Then, try to run RoboViz again and see if the problem persists. Let me know if that works.

Thank you for telling me to update. After updating it to the latest version the exception got resolved but now I am getting a different error which seems to be very similar to the previous one.

here it is:

The error is indeed the same. The error just looks different because we recently restructured a lot of the code. As far as I can tell, this error is not related to RoboViz directly but rather to JOGL or your system. Can you post the output of the command glxinfo?

[FaazAbidi]

Sure. Here you go,

It is a RoboViz <-> GPU Driver issue. RoboViz uses OpenGL2 (I really don't know why that's a hard coded dependency). I'll try to fix this and send you a version with the fix, as soon as my computer stops sabotaging me.

Thank you so much @Seil0! Looking forward to the fix. I hope your computer behaves.

I was a little quick to promise a fix on this issue. It turns out the RoboViz Renderer heavily uses OpenGL2 functions. To fix this one would need to port the renderer to a other opengl profile (opengl4), which I currently can't do.

That's unfortunate. Any suggestions for fixing this from my end?

Since your screenshot shows GL compat version: 4.6, can you tell me:

• your GPU model
• your OS and it's version

[FaazAbidi]

• GPU Model: Intel HD Graphics 520
• OS: Ubuntu 20.04.3 LTS

I found the solution for this. There is a command for Mesa that lets you specify the profile. Whoever is facing similar issue can run Roboviz using this command: MESA_GL_VERSION_OVERRIDE=3.0 ./roboviz.sh
