Hi. After some more debugging I got next:
file <osgUtil/LineSegmentIntersector.cpp> "lost" Transform/Geode/drawable reaches this expression line 388: drawable->accept(ti); but next "if" executes time by time(drawable->accept fails in some situations). if (ti._hit) It means that error is in the drawable->accept(ti). I can't say any more because I have not enough knowledges about OSG. ( I think I have found place where error with intersection is. While debugging I got next results: In file <osgUtil/IntersectionVisitor.cpp> void IntersectionVisitor::apply(osg::Node& node), void IntersectionVisitor::apply(osg::Group& group) etc. all ok, names of intersected objects appeares all times it must be (std::cout << "Node appy= " << node.getName() << std::endl;) file <osgUtil/LineSegmentIntersector.cpp> function void LineSegmentIntersector::intersect(osgUtil::IntersectionVisitor& iv, osg::Drawable* drawable) in line 338 expected name also appeares but line 444 (osgUtil/LineSegmentIntersector.cpp) (insertIntersection(hit);) sometimes never executes! It means that problem somewhere in osgUtil/LineSegmentIntersector.cpp ) 28.07.08, 22:44, "GMD GammerMaxyandex.ru" <[EMAIL PROTECTED]>: > Here is the small example, where described problem appeares.
