Hi Martin, I would recommend using the osgUtil::IntersectionVisitor rather than the osgUtil::IntersectVisitor as the later is deprecated and only kept around for backwards compatibility.
As for examples of getting the texture coords of a ray intersections have a look at the osgViewer::InteractiveImageHandler implementation in src/osgViewer/ViewerEventHandlers.cpp as it does just this.
