[vtkusers] VTK in a multi-threaded program

[Richard Whitehead]

David,
Unfortunately I am now in a really bad place.  I have some long-winded
calculations to do and then visualise, which I want to do in a background
thread.  This is for a commercial application and hanging the GUI is
completely unacceptable.  I have now invested several man-months into VTK
and I have to decide whether to drop it.  I think the only sensible thing I
can do is to get rid of VTK from my calculations and only use it for
visualisation.
Many thanks,
Richard
