AW: [vtkusers] transforming objects due to user interaction II

Hi, 

first of all, thanks for replying 

I'll try to specify the problem once again:

When setting a vtkRenderWindowInteractor, the user can rotate or translate the actor using the mouse buttons. What I want to do: Get the actor (somehow back from the window) in the exact position where it was rotated/translated by the user.

I visualize vtkPolyData; after closing the vtkRenderWindow it would be nice to get another (or the modified) vtkPolyData encapsulating the object/actor in the position where it was rotated/translated. 

(Therefore, I think I should implement a kind of TerminateApp method but I do not know how to get the latest actor position... )

It would be really helpful, 

if you can give me a hint !

Harry

	Hi Bauer,
	
	Your e-mail is clear up to the point where you talk about modifiing after
	closing a window !
	
	Can you specify please ?
	
	Thanks !
