Hi, when i run the osgkeyboardmouse example in OSG2.2.0 with "fountain.osg" model, it was quite right in "LineSegmentIntersector" mode, but while i pressd the 'P' key to switch to "PolytopeIntersector", then it was terminated by assert! But, when i run it with "cow.osg" model or else, it was OK, i found that the problem was caused here: " parent = (nodePath.size()>=2)?dynamic_cast<osg::Group*>(nodePath[nodePath.size()-2]):0; " but i could not work it out, please have a check with that, thanks.....
