[vtkusers] which events are supported by the volume renderer?

[Cuypers Wouter]

I'm trying to add an observer to the vtkVolumeRayCastMapper for monitoring start/end/progress events. But the mapper doesn't seem to send any, is there another way for monitoring this?
 
Thank you and regards,
 
Wouter
