Hi Robert,
Thanks for your suggestion, but maybe I misleaded you to the wrong way.
Please let me re-organize my problems again.
I have built the earth model ( earth.osga ), the region model ( e.g.
Beijing.osga, which created by osgdem with img file and dem file), and the
object models (e.g. car.osg, plane.osg, ...). I want to load the three kinds of
models in one viewer, and locate the Beijing.osga and car.osg, plane.osg, etc.
in specifically position of the earth model (earth.osga) with Lon/Lat/Height
coordinate. How can I do it?
thanks.
Minghong
