Hy everybody, I am trying to use vtkPointPicker, but I noticed that
sometimes, when I pick some point on an object, the returned point is the
"back one", that is, assuming a closed surface, the second point along the
ray. I noticed that the tolerance has no effect on this behavior.
Can somebody give me a hint on why this is happening?

Thank you

     Luca
