Hi,
How can I add georeference point to a model I have ?
(I have some tiles of model. All of them are georeferenced to the real location
by a single point which I have in txt file. Is there a way to 'tell' osg to add
the fake location to the point ?)
If you need to offset it to a geographic position in terms of
transforming it there you can use the CoordinateSystemNode which allos
you to calculate the local_to_world matrix which will put your node into
a geocentric coordinate frame based on your geographic (lat/lon)
position. Check the CoordianateSystemNode::EllipsoidModel.
Be sure offset all your stuff with these matrix transforms and not to
use absolute geocentric vertex coordinates, as the latter will lead to
precision problems.
If you are talking terrain as heightmaps etc. take a look at VPB/osgEarth.

Thank you!
