Openflight databases seem to use this user-data at the root node

Unfortunately this class doesn't seem to have a serializer for the
osgXYZ file formats. What is the best way to add such
serialization capabilities?
Been a very very long time since I heard mention of the
osgSim::GeoographicLocation class... just been sitting there quietly
minding it's own business.
The issue right now is, that I somehow have to distribute the lat,lon
origin in some OpenFlight centric workflow. I could totally do this
differently by transforming the information into my own format.
Looking at the implementation now the two parameters that need to be
serialized at the latitude and longitude paramters. If these used the
setName()/getName() convention then it'd be easy to add serializers
using the standard ADD_DOUBLE_SERIALIZER( Name, 0.0); serializers (for
instance see the usage in src/osgWrappers/serializers/osg/ ).
As these don't follow the setName/getName() one will either have to
write a custom serializer for it or simply change the naming across to
the setName()/getName() convention that the almost all of the OSG
uses. I'd be inclined to do the later. Then just add the
GeographicLocation serializers to the
src/osgWrappes/serializers/osgSim. This would mean that the change
could only be add to OSG master and no backported to OSG-3.4 or
OSG-3.2 as the ABI would change, but personally I'd be happy with this.
I'll try to do this then and present the submission when I find the time.
Cheers
Sebastian
Robert.
