Hi Aerkis, all the intersection routines you find under osgUtil are meant just to find intersection (picking being the most common usage), not to clip polygons. For that purpose you should instead look at osg::ClipPlane/ClipNode which implement GL clipping.
I don't think there's a routine which clips by a bb extents, you should implement that by using 6 different clipping planes yourself. See osgClip example for a reference.
