From Maria Ten, "The constructor method of the EllipsoidLocator of osgTerrain assumes

Browse Source 
that the terrain is always the Earth planet. I changed the constructor
method to accept the Equator radius and the Polar radius like
parameters. By default, it assumes the Earth radius for the
EllipsoidLocator. I added a setEllipsoidModel method, too.

Now, we are developing some libraries for a GIS applicacion, and our
libraries can visualize terrains of planets like Mars. I think that is
a interesting change."
