thanks, I found something.
but I raised a other trouble(it's not my month, all that for a teacher :-(
),
with QT, I can't use osgViewer , I have to use osgSimpleViewer . if I use
osgViewer --> core dumped (see code below) . (I duno if it's normal)
but in osgSimpleViewer I haven't computeIntersection function.
so what I have to do make my own viewer?? or implement compute intersection
in my subclass of SimpleViewer.??

HI Elekis,
The difference is simply in the data structure used to store the
intersection hits. The osgViewer is based on the new
IntersectionVisitor rather than the old IntersectVistor. For the new
viewer you'll just need to use the LinerIntersector::Intersections
structure. Have a look at the interface. As check the picking code
in osgpick or osgmanipulator.
