disabling the picker's bounding box

[Patric.Weis at mycrona.de]

Hi Maurizio!

Simply derive your own interactor style class from vtkInteractorStyle and
overload the virtual function vtkInteractorStyle::HighlightActor().
To disable the bounding box  make your HighlightActor() a dummy function.
To change the the aspect you can implement all or parts of the original
source code of HighlightActor() in vtkInteractorStyle.cxx. You need vtk 3.0
at least to be able to do that!

Good luck!
