vtkplotter.dolfin.plot not working as usual

Hi Marco,

I was experimenting with vtkplotter.dolfin.plot in Jupyter notebook. I am noticing some unusual behavior between my local machine and a docker container that I built on binder. A sample notebook with the container.

Initial problem on the container:

I was having trouble in making embedded inline plots using jupyter (+dolfin). A simple example like

from dolfin import UnitCubeMesh
from vtkplotter.dolfin import plot
plot(UnitCubeMesh(2,2,2))

would render the plot in a separate window, but on the container it would spit out the error

ModuleNotFoundError: No module named 'vtkOpenGLKitPython'

Try Installing MESA: namely libgl1-mesa-glx for rendering graphics

Following this I simply installed libgl1-mesa-glx libsm6 using

apt-get install libgl1-mesa-glx libsm6

on both my local machine and the container. Now everything works perfectly fine on the container, but I do not get any plot on my machine (neither embedded nor in a separate window). Would you happen to know the issue ?

Also attached is the notebook’s output.pdf on my machine. Note that everything works smoothly when running a python script on the terminal, namely:

from dolfin import UnitCubeMesh, Function, FunctionSpace
from vtkplotter.dolfin import plot
import numpy as np
msh = UnitCubeMesh(4,4,4)
V = FunctionSpace(msh, "CG", 1)
w = Function(V)
w.vector()[:] = np.linspace(0,1,V.dim())
plot(w)

runs absolutely fine on the machine.

Thanks Marco. I think this is (partially) resolved at least to the extent of not being related to vtkplotter.

I see… unfortunately the rendering part in jupyter is delegated to other applications so it not under control of the vtk library and has a lot of limitations… Thanks for reporting these issues.
