Textures would work if all those planes are of one type and have the same livery, which is an unrealistic scenario. A more realistic scene that a user would see (hopefully) in FG is a dozen different types of planes belonging to a dozen different airlines. Using textures for details would require huge textures per aircraft-type per airline, and would result in performance cost going through the roof; and that's excluding the textures that would be already presented in the airports. Performance would still degrade if all those aircraft and buildings have high geometric details, but geometries wouldn't eat up memory as quick as textures would. Beside, one could always turn off a portion of the geometries when they aren't needed. Anyway, I think we are getting a bit ahead of ourselves here. FlightGear starts to struggle/struggles with merely 10 aircraft on the scene. I don't think users would be able to see 100 planes in the same scene anytime soon. :P Ampere _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
