Just to make a slightly off thread comment: All I can say is that Ron's comments on this list have been courteous and professional and I also don't remember any negative comments in referral to him, so I'm also rather puzzled by this statement. > So I'll ask a dumb , non developer question: What exactly is the purpose > of this directory setup ? > Will it affect my own attempt to update local scenery ?Is it meant to > make scenery additions easier ? Basically, this new scheme will serve a number of purposes. First and foremost, coupling airport related data to the scenery makes it a lot easier and more flexible to update the and maintain the scenery. Currently, (almost) all the airport data that is used by FlightGear is read from apt.dat. This not only means that we have to parse 20000+ airpport to get the startup location for just one of those, it also means that we are limited in doing updates to the scenery: Suppose you would finetune the runway layout of your favorite airport. If this update were to be included in a new scenery release, you'd find out that FlightGear would place you off the runway, because the original startup position is still calculated based on an apt.dat file, which does not reside in the scenery, but in the base package. By moving this information out of the base package, and including it in the scenery, maintaining the scenery will become much better maintainable. Also, separating this information into separate files, mean less IO at program initialization, and therefore faster startup times. Hope this helps, Cheers, Durk ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
