[osg-users] osg Coordinate system

[Trajce Nikolov NICK]

Hi,

Here you can find some snippets:
https://github.com/CCSI-CSSI/MuseOpenIG/blob/master/Plugin-CIGI/IGPluginCIGI.cpp

but you rotate it normaly as in flat earth and then apply the
transofrmation for that geo location:

osg::Matrixd l2w;
osg::EllipsoidModel em;
em.computeLocalToWorldTransformFromLatLongHeight(osg::DegreesToRadians(lat),osg::DegreesToRadians(lon),alt,l2w);

osg::Quat hpr;
osg::Matrixd finalMatrix = osg::Matrixd::rotate(hpr) * l2w;
