I am a newbie to OSG and think I just need a little pointing in the right
direction.
I have managed to build and install OSG with no problems on a WinXP target.
On following the provided examples I have managed to create a small viewer
application that can load terrain and a couple of vehicle models and have the
vehicles move around on the terrain. So far very straight forward.
I have also managed to use osgdem to build a terrain model from imagery and
DTED2 data. Thank you for the wonderful support tools provided with OSG for
being able to do this and many other geographic based tasks.
I seem to have run into a stumbling block in trying to figure out how to
reference my scene using geographic lat/lon coordinates. Currently I am
positioning the models and such with what appear to be unit less values around
an origin of (0, 0, 0).
I would like to be able to position my models on the terrain using lat/lon
coordinates and to also center my view on the terrain using lat/lon
coordinates. I plan on using a single geographic Datum "WGS84" and Lat/Lon in
decimal degrees.
Could anyone point me in the direction of a Tutorial, Sample or explanation on
how to do this?
Thanks in advance for any help on this.
Dave
