[Flightgear-devel] Request for comments: Airway database
Hi Folks, I just finished some initial experiments in loading the Robin Peel airway database for flightgear. The code is based on the ground network code that I wrote for AI taxiway following. While I have stuff working right now, one major problem is becoming apparent: It takes approximately 6 to 7 minutes to load and initialize the entire airway database on my machine (yikes). The major reason for this is that each route segment in Robin Peel's database is defined by the full coordinates of each start and end waypoint. The airway and ground networks operate by storing the waypoints and the routes separately. Therefore, for each Airway segment, I need to look up whether the defining waypoints have already been loaded, which is quite computationally intensive. My ground network code, on the other hand, reads data in which the waypoints and the route segments are stored separately to begin with, which makes it much faster to load. Right now, I can see a number of ways to proceed with this. My major objective is to use the airway database to create more realistic AI traffic behavior, but for just that purpose, I don't actually need to load the airway database into flightgear. I could also choose to pregenerate all the AI flightplans offline and let FlightGear read those on demand. I'm wondering though if there would be any future need for airway information inside FlightGear itself, for example in modeling GPS receivers or flight management computers. If so, it would still be worthwhile to convert the data into a native format that could much more rapidly be loaded into flightgear. Cheers, Durk --- This SF.net email is sponsored by: Splunk Inc.

[Flightgear-devel] Compiling FlightGear question
Hi Ive just discovered FlightGear and would like to compile the source code myself. Ive downloaded all the appropriate packages and downloaded and installed Cygwin as outlined in the flightgear getting started document. Im trying to install SimGear, the ZLIB library as per the instructions (page 94 of the flightgear getting started pdf) but when it comes to typing ./configure an error occurs saying there is no such command. Im using Windows XP and opening a command prompt on the zlib folder which has been decompressed with WinRAR. Am I doing this correctly using a dos box? Ive looked up DOS commands on the internet and the commands Im supposed to type are nowhere to be seen. I have some basic C++ programming knowledge using Visual C++ but have no experience of makefiles etc. Regards, Chris

You need to run all the commands from the cygwin command shell; not from a dos box. HTH, Durk --- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems? Stop!

Re: [Flightgear-devel] OT: Saturday night movie review
Interesting to hear that about you Curtis! And now I will see that movie! I wonder how many others of us got interested in flying and flight simulation because of a lot of moving around ( probably by flying) in our youth? Probably pretty much why I got into it now that I think about it. You know its been a long time since I have posted here (the first months actually on compuserve probably discussing feature sets and programming methodolgy!) but I have to say even though I always promoted the idea of a volunteer cooperatively written flight sim so heavily in all the flight sim magazines I was starting in the USA I none the less have been very impressed with flightgears development over the past year especially.
