You have access to all the source code you need - the OpenSceneGraph/examples directory contains over 170 examples, what is missing is your effort at searching for relevant materials. I am not going to give you the answer as you need to develop the skill at finding answers without needing the community to hand hold every line of code. You've been given the hint EllipsoidModel so go and do a search in the OSG examples for usage of this class i.e. cd OpenSceneGraph/examples grep EllipsoidModel */*.cpp You'll get: osgautocapture/osgautocapture.cpp: csn->getEllipsoidModel()->convertLatLongHeightToXYZ(lat, lon, alt, eye.x(), eye.y(), eye.z()); osgfadetext/osgfadetext.cpp: csn->setEllipsoidModel(new osg::EllipsoidModel()); osgfadetext/osgfadetext.cpp:osgText::Text* createText(osg::EllipsoidModel* ellipsoid, double latitude, double longitude, double height, const std::string& str) osgfadetext/osgfadetext.cpp:osg::Node* createFadeText(osg::EllipsoidModel* ellipsoid) osgfadetext/osgfadetext.cpp: csn->addChild(createFadeText(csn->getEllipsoidModel())); osggpx/osggpx.cpp: osg::ref_ptr<osg::EllipsoidModel> em = new osg::EllipsoidModel; osggpx/osggpx.cpp: osg::ref_ptr<osg::EllipsoidModel> em = new osg::EllipsoidModel; osggpx/osggpx.cpp: osg::ref_ptr<osg::EllipsoidModel> em = new osg::EllipsoidModel; osgintersection/osgintersection.cpp: //osg::EllipsoidModel* em = csn ? csn->getEllipsoidModel() : 0; osgmultitexturecontrol/osgmultitexturecontrol.cpp: osg::EllipsoidModel* em = csn->getEllipsoidModel(); osgposter/osgposter.cpp: csn->getEllipsoidModel()->convertLatLongHeightToXYZ( osgsimulation/osgsimulation.cpp: csn->setEllipsoidModel(new osg::EllipsoidModel()); osgsimulation/osgsimulation.cpp: osg::EllipsoidModel* ellipsoid = csn->getEllipsoidModel(); This should give you plenty of code to look at. Run these examples and see if any function in the way you want. Also have a look at the CoordiateSystemNode and ElipsoidModel headers, there are methods that do exactly what you need, you just need to be able to read C++. Spend the time with these headers and examples and you'll learn a lot about these particular classess, but even more important you'll develop your skill as programmer, a key one is being able to understand 3rd party code.
