I can't speak for whether VTK has something to do this now.  In the past 
what I've done when I needed this, was to create another renderer in the 
lower left corner of the render window containing only an axis.  You can 
then share the camera between these two renderers if you don't mind pan and 
zoom affecting the axes, but what I did was modify the Tk-Interactor to 
insure that any rotations in the main renderer were also performed in the 
axis renderer.  Couldn't say how to do this with the C++ based interactors.

Hope that helps.
