Hi, Thank you everyone for your replies. In fact, I made a mistake because I built my terrain with VPB with the option --geocentric so my terrain is geocentric. I didn't remember anymore. In fact, I rotate the terrain and that's why it seem flat. But your answers helped me a lot because I might build flat terrain.
Thank you! Cheers, lucie ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=32343#32343 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
