[vtkusers] Get the orientation of vtkPlaneWidget

[Stefan Maas]

Hello,

can someone tell me an easy or tricky way to get the orientation of an
vtkPlaneWidget?
I want to use it as an "auxiliary-object" to align an vtkActor (an implant).
My idea was something like this:
When I move (translate, rotate) the planeWidget, the actor should take the
position and orientation of the planeWidget.
Setting the position works by:

actor.SetPostion(planeWidget.GetPostion()); //java 

But for the orientation it doesn't work because there is no method called
"planeWidget.GetOrientation()".

Any Ideas?

Thanks!

Stefan
