[vtkusers] refreshing and updating the objects

[Giancarlo Amati]

Hello everybody,

this question hasn't found any answer yet...so I'll keep posting: 

I need to refresh the vtk scene as I change some properties of actor already in there. I select each actor with vtkPicker and then i chance some properties like opacity and transformation.
but If I don't explicitly click on the area and move the camera, it doesn't happen anything....
To refresh I thought it was the ResetCamera() of the vtkRenderer but it doesn't really work.
So, any other idea?!

Kind Regards.
Giancarlo
