Hi,
I created virtual earth as follows,
osg::Node* createEarth()
{
osg::TessellationHints* hints = new osg::TessellationHints;
hints->setDetailRatio(5.0f);
osg::ShapeDrawable* sd = new osg::ShapeDrawable(new
osg::Sphere(osg::Vec3(0.0,0.0,0.0), osg::WGS_84_RADIUS_POLAR), hints);
osg::Geode* geode = new osg::Geode;
geode->addDrawable(sd);
std::string filename =
osgDB::findDataFile("Images/land_shallow_topo_2048.jpg");
geode->getOrCreateStateSet()->setTextureAttributeAndModes(0, new
osg::Texture2D(osgDB::readImageFile(filename)));
osg::CoordinateSystemNode* csn = new osg::CoordinateSystemNode;
csn->setEllipsoidModel(new osg::EllipsoidModel());
csn->addChild(geode);
return csn;
}
But with the above ellipsoidal model I could not locate any geographic location
accurately. Means that, not able to locate any position for given latitude and
longitude accurately. What should be done more?
Thanks
