I have created an earth model with VPB ( an ellipsoid with earth texture) by the instruction post in http://www.openscenegraph.org/projects/osg/wiki/Support/UserGuides/osgdem. (osgdem --bluemarble-west -t land_shallow_topo_west.tif --bluemarble-east -t land_shallow_topo_east.tif -l 8 -o earth.ive -a earth.osga)
I want to add a ground station model(e.g, School.osg) to the earth model( earth.osga) at specific position(e.g., Lon/Lat - 37.33/33.2), and I want to post the dem and texure of the region in which a osg model(school.osg) is positioned. Let's assume the dem and texture have proper projection infomation, which means the dem file and texure img file have geo-info(e.g., GeoTiff Format Files). How can I post them(plane object) to an ellipsoid model(earth.osga) at specific position?? thanks. 2009-04-07 Minghong Xie
