[vtkusers] Problem about world and local coordinates

Hi,

A small example : it's easier to understand...

I build a vtkAssembly v1 that I add to the world.
So, I build another vtkAssembly v2  that I add to v1.
If  I change the coordinates of v2, I change these in relation to v1.
My question is  I would like to know easily the coordinates of v2  in 
relation to the world ?
Do it exists a fast method to have this information ?

regards

Benoit
