Hi everybody I have a question about intersection. I try to intersect lines with the osgUtil::PolytopeIntersector class. This works fine. Now how can i get the picked line from the picked geometry? I want to have the two vertices from the picked line...
Thanks a lot! Daniel My Code for intersection; osg::NodePath& nodePath = intersection.nodePath; node = nodePath.back(); if ( node.valid() ) { std::cout << " Hits "; std::cout << node->className(); std::cout << " - NodePath size: "; std::cout << nodePath.size(); std::cout << std::endl; osg::ref_ptr<osg::Geode> pickedGeode = dynamic_cast<osg::Geode *>(node.get()); osg::ref_ptr<osg::Drawable> pickedDrawable = pickedGeode->getDrawable(0); osg::ref_ptr<osg::Geometry> pickedGeometry = dynamic_cast<osg::Geometry*> (pickedDrawable.get()); osg::ref_ptr<osg::Vec3Array> pickedVertexArray = dynamic_cast<osg::Vec3Array*> (pickedGeometry->getVertexArray()); std::cout << " -> Num of Triangles: "; std::cout << pickedGeometry->getPrimitiveSet(0)->getNumPrimitives(); std::cout << std::endl; std::cout << " -> Used Vertices: "; std::cout << pickedGeometry->getPrimitiveSet(0)->getNumIndices(); std::cout << std::endl; std::cout << " -> Number of Vertices from the Geometry: "; std::cout << pickedVertexArray->getNumElements(); std::cout << std::endl; } _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
