Thanks for your answer.<br>
This is not what I meant. The new parameters incorporate even the
objects visualilsed itself.<br>
So they will need to be created again as well.<br>
<b><br>
I want to go through the pipeline to update it, not just to update the
render window!</b><br>

I made some callback functions which will allow the user to alter
different options of the displayed objects.<br>
Is there a way to <b>tell the complete render pipeline to update itself</b>
with the new set of settings?<br>
<br>
Currently I will have to exit the Render Window and restart it to have
the new settings applied.<br>
