[vtkusers] animation/callback question

[Akshay Sthapit]

Hi

I need to set up VTK so that it keeps rendering the screen because I'm
changing the cursor (vtkActor) position using an external 3d pointing
device.  Any suggestions/advice would be much appreciated!

I'm currently using glut which comes with a handy callback function
called glutIdleFunc() which does this for me.  I was wondering if VTK
could do something similar.

Thanks!
