[vtkusers] How suitable is VTK for 'live' display during an experiment?

[Vladimir Lazunin]

Maybe I misunderstood, but why do you need a 3D library to make a 2D 
picture? Yes, VTK can do the job, but to me it seems like a huge 
overkill - why not to use an imaging library instead? I guess both 
Tkinter and GTK+ support at least primitive bitmap operations.
