Vedo: Using vedo without X server?

[MarkusRosen]

I have been using vtkplotter with success on my local machine, but for a larger project I want to move my code to a server. Problem is, I get the following error:

ERROR: In /work/standalone-x64-build/VTK-source/Rendering/OpenGL2/vtkXOpenGLRenderWindow.cxx, line 1223
vtkXOpenGLRenderWindow (0x4fc59e0): bad X server connection. DISPLAY=Aborted (core dumped)

I use the option offscreen=True and save screenshots of my renderings, but still it does not work. Do you have any idea if this could work in some way without an X server?

Hi @MarkusRosen this seems a general limitation of VTK which needs to be build with osmesa support, see here.

You can still use all vtkplotter classes to do your analysis and then only save some individual output meshes or volumes to file.

I'm doing some tests now to see if it's doable to export a whole scene in either npy obj or x3d formats to be later visualized..

@MarkusRosen ,
the following works for me:

that is with the vtk version from conda (8.2.0)

Thank you very much for your quick help! I wasn't able to find this comment. Thanks!
