OpenGL and GDML

[meyerma]

Hello, I get a glitch when I try to open a GDML file with OpenGL.

X3D is fine, but less interesting (No GUI as good as OpenGL)

TGeoManager::Import("my.gdml");
gGeoManager->Draw("ogl");

Info in <TGeoManager::Import>: Reading geometry from file: /media/psf/Home/Work/Analysis/escalade-workspace/share/gdml-compass2015/TargetAbsorber.gdml
Info in <TGeoManager::TGeoManager>: Geometry GDMLImport, Geometry imported from GDML created

Am I doing something wrong ?
Thank you !

Hi, nothing to do with the geometry, but with the installation of the graphics drivers on your machine. Try fixing this by fixing the gl support and then recompile root to autodetect and link against the new libraries. Should work after.

Unfortunately I couldn’t find the solution.
But thank you very much for the clarification!
