Hi:
The solution was in the same example code I am using (osgpick), but
Glenn Waldron from osggis told me the hint.
Quotiong: {
1) Find the osg::CoordinateSystemNode (CSN) atop your VPB database scene graph;
2) Get the EllipsoidModel from the CSN
3) call EllipsoidModel::convertXYZToLatLongHeight().
}
Tha's exactly what osgpick does to get the current elevation.
Regards,
-- A.
