[vtkusers] transforming object due to user interaction

[Bauer Harald]

Dear VTK Users, 

Info: I'm using vtk4.0 with C++

can anyone tell me how to transform an object due to arbitrary user interaction ??

To be sure that the problem is ok - in more detail: 

----------------------------------------------------

It's easy to visualize objects in a vtkRenderWindow. 

Moreover, it's easy to enable a vtkRenderWindowInteractor to enable user interaction (rotation, zooming, ..)

Is there also a (simple) way to transform the visualized object according to the interaction actions 

when closing the window for example ???

----------------------------------------------------

I hope, that - even if it may be a very easy question - someone can give me an answer; 

best would be a short programming example ;-)

Greetings, 

Harry
