VTK + PyQt5 + VirtualGL not working
Dear VTK developers,
We have an issue with our 3D visualization software which uses VTK, through Python bindings. Although VTK has been working with no problems with VirtualGL, recently we have implemented a GUI for our visualization routines. The problem appeared when we tried to use this GUI remotely through VirtualGL.
We get the following error message:
` [VGL] NOTICE: Automatically setting VGL_CLIENT environment variable to [VGL] 131.169.206.101, the IP address of your SSH client. ERROR: In /data/netapp/fla/plasma/software-max/source/VTK-git/Rendering/OpenGL2/vtkOpenGLRenderWindow.cxx, line 725 vtkXOpenGLRenderWindow (0x2ef7b00): GLEW could not be initialized.
Segmentation fault `
The problem also appear with a much more simple program that we took from the VTK examples: vtkQtSimple.py
This script runs smoothly in a local computer, but it fails when using vglrun (VirtualGL).
This is a critical issue for us: Normally we store our simulation data in Supercomputing clusters, and therefore, it is a must to use VirtualGL to visualize it without needing to copy large amounts of data to our personal computers.
Any help is much appreciated. Thanks!
