Beside the picking problem stated above, I wonder if the
PolytopeIntersector can intersect osgText::Text objects? I'd like to
implement context menus so I need to pick one of many Text objects
attached to the same unique Geode, but it looks like that the
intersector retrieves just the Geode and not any of its (text)
children...is this the expected behavior?
Thanks.

Hi,
the PlaneIntersector does intersect text-objects, so if the
PolytopeIntersector uses the PlaneIntersector, it should do it.
See here:
(the red line is the intersection).

The PolytopeIntersector is only a partial implementation which needs
replacing with a full implementation. An OSG user did extend it to
work better, but didn't submit it an form ready for integration, I was
expecting a later rev of this work, but it hasn't appeared yet. I'll
need to do some searching through the archives to track it down.
Robert.
