[vtkusers] auto-update renderer ?

[Laurent Mundeleer]

Hi all,

I'd like to update an actor in my renderer every x ms (like for an 
animation, or in this case for tracking).
I have a vtkRenderWindow, a vtkRenderWindowInteractor, and a custom 
interactorStyle inheritated from vtkInteractorStyleTrackballCamera.
This is what I've tried :
I have overrided vtkInteractorStyle::OnTimer, adding a few lines to move 
an actor.
But I don't know how to specify that OnTimer must be call every second 
for example. In fact, it's never called, so maybe I didn't choose the 
right function to override.
Is there any function who's called often in the interactor ? Or could I 
handle an automatic and periodic event ?

Thanks for any help.

Laurent
