Hi Alex, It's difficult to work out what you are doing as you don't specify what you mean by intersection. Do you mean you are using osgUtil::IntersectionVisitor and one of the Intersector subclasses like LineSegmentIntersector?
As a general note, the OSG's Intersection classes don't know about the eye position so can't use the same LOD child selection metrics as are using during the cull traversal. Instead the highest resolution LOD child is selected and traversed. Have a look at the LOD::traverse(NodeVisitor&) implementation in OpenSceneGraph/src/osg/LOD.cpp to see what it done. Robert.
