AW: [vtkusers] Updating vtkRenderWindow asynchonously

[Stefan Bruckner]

Well, that's my problem. I use VTK within in a Qt-GUI application.
Performing rendering from within a seperate thread causes xlib errors,
because Qt's GUI thread also tries to access the xserver. There is a way
to lock the Qt library, which gets rid of these errors, however, I want
the GUI to remain responsive ...

I thought maybe an asynchronous render command implemented within VTK
would enable me to work around the problem.

Only if you perform the render in a seperate thread.
