In addition to what Adrian said (that osgpick focuses on triangles), I
believe (but have never done it, so I might be wrong) that you can pick
points using a PolytopeIntersector. Unfortunately this is not very
documented. Have a look at how the osgpick example's source sets up a
LineSegmentIntersector, and try to do the same thing for a
PolytopeIntersector (setting up a valid polytope for what you want).
Hope this helps,
J-S
