Hi, computeLocalToWorldTransformFromLatLongHeight take lat,lon as radians, not degrees.

But the model is positioned at some strange place. The way I do placing is, ............... ..................... osg::Node* cessna = osgDB::readNodeFile("cessna.osg"); if (cessna) { double s = 200000.0 / cessna->getBound().radius(); osg::MatrixTransform* scaler = new osg::MatrixTransform; scaler->addChild(cessna); scaler->setMatrix(osg::Matrixd::scale(s,s,s)*osg::Matrixd::rotate(rotation)); scaler->getOrCreateStateSet()->setMode(GL_RESCALE_NORMAL,osg::StateAttribute::ON); osg::MatrixTransform* mt = new osg::MatrixTransform; mt->addChild(scaler); .... .... rot.makeRotate(osg::DegreesToRadians(90.0),0.0,0.0,1.0); .... ... osg::EllipsoidModel* ellipsoid = csn->getEllipsoidModel(); if (ellipsoid) { osg::Matrixd matrix; lat=11.0; lon=78.0; ht=100.0 * 1000.0; ellipsoid->computeLocalToWorldTransformFromLatLongHeight(lat,long,ht,matrix); matrix.preMultRotate(rot); mt->setMatrix(matrix); } csn->addChild(mt); ....... .... The coordinate system node is of the earth file (Geotif). I wud like to know the mistake I do.
