Hi Robert,

But I can't use nodePath like expected. To play a little bit with the nodePath I wanted to print all names of nodes So my first try was: Code: bool nodeFound = false; for(osgUtil::LineSegmentIntersector::Intersections::iterator hitr = intersections.begin(); hitr != intersections.end(); ++hitr) { osg::NodePath path = hitr->nodePath; for(osg::NodePath::iterator hitNodeIt = path = hitr->nodePath.begin(); hitNodeIt != path = hitr->nodePath.end(); ++hitNodeIt) { if (hitNodeIt->getName()) { nodeFound = true; std::cout << hitNodeIt->getName(); } } if (nodeFound) break; } Then I got: > IntelliSense: Es ist keine passende benutzerdefinierte Konvertierung von " > "std::_Vector_const_iterator<std::_Vector_val<osg::Node *, > std::allocator<osg::Node *>>>"" in > ""std::_Vector_iterator<std::_Vector_val<osg::Node *, > std::allocator<osg::Node *>>>"" vorhanden. So I tried this: Code: bool nodeFound = false; for(osgUtil::LineSegmentIntersector::Intersections::iterator hitr = intersections.begin(); hitr != intersections.end(); ++hitr) { for(osg::NodePath::const_iterator hitNodeIt = hitr->nodePath.begin(); hitNodeIt != hitr->nodePath.end(); ++hitNodeIt) { if (hitNodeIt->getName()) { nodeFound = true; std::cout << hitNodeIt->getName(); } } if (nodeFound) break; } But this won't compile too: > error C2039: 'getName': Ist kein Element von > 'std::_Vector_const_iterator<_Myvec>' > error C2839: Ungültiger Rückgabetyp 'osg::Node *const *' für überladenen > Operator '->' > IntelliSense: Der Ausdruck muss den Typ "pointer-to-class" aufweisen. > Any idea?
