Root crashes while plotting geometry with the "ogl" option

[littlepi]

Dear ROOT experts,
I am using root6 in Ubuntu 16.04. I build root with the default build options. It seems that I can not draw the 3D geometry with opengl. For example, I run the script “/tutorial/geom/tank.C”, and will get the segmentation violation error.

That’s weird. I just tried it on may mac. It is fine. Which exact ROOT version are you using ? can you post the errors messages you get ?

[littlepi]

It is ROOT 6.12.04. There is no error message actually. Just the segmentation fault message. You can see the screen shot below:

We had an issue with GL in 6.12 at some point. 6.12 is now 6.12/05 … can you try with 6.12/05 ?

[littlepi]

Thanks, I will try it soon.

Besides, I have more information about the error. As shown in the previous post, after the segmentation error, a TPad will be popped out and the geometry will be ploted normally in 2D. Then if I manually select view->view with->OpenGL in the menu, the 3D geometry will show up correctly.

@littlepi

View->view with->OpenGL in the menu, the 3D geometry will show up correctly.

Ah ok … weird …

I am still having issues with the latest master:

GDML Import Draw Blank Canvas

Continuing the discussion from GDML import doesn't draw: I just attempted to draw this geometry again with the current master (commit 6a12464be798b421d5) and I’m still getting a blank canvas. PS what does root-config --git-revision provide? $ root-config --git-revision v6-11-02-1327-g6a12464be7

The post about the JIRA ticket that was mentioned as fixed earlier:

GDML import doesn't draw

Hello I am also seeing this error, and it worked in the previous version of ROOT. There is a JIRA ticket here: https://sft.its.cern.ch/jira/browse/ROOT-9154 Let’s hope it gets fixed soon, because I am usually very impressed with the robustness of ROOT’s GDML visualisation (compared to Geant4 that is…)!!!
