Q: vtkMultiThreader. Threads. How to use? Example?

[Audrius Stundzia]

Hi Lisa,

Thanks for your prompt reply. Much appreciated.
I'll have a look at the examples.

Basically, I want to spin off several vtkRenderWindowInteractor objects as
seperate threads so that I can interact with the windows while my program
goes off and does other stuff. Doable?

Best regards, 

Audrius
