To elaborate on Robert's reply... I've had good luck with leaving the models in a projected coordinate system, and also storing a geographic tie point for each model. OpenFlight, for example, has a location in the file header for geopositioning information. The geographic position (in unprojected lat/long) corresponds to the model's origin.
As long as the coordinate system you use for rendering corresponds to the model's projected coordinate system, everything works fine. If the coordinate systems are different, this will still be "good enough" for small models, but you'll notice inconsistencies with sufficiently large models. Hope that helps, -Paul _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
