Yup - FlightGear. And by pure chance you posted your message to the list ;) FG has a I/O subsystem that allows you to read data from an external application or file. It is sufficiently flexible that you can define the data that you are reading. Have a look under the Protocol sub-directory. There is a README.Protocol file that should provide you with all you need. Also, see the playback.xml file for an idea of how this has been used. Assuming you have position and/or velocity information as well, you'll want to use the "--fdm=null" command-line parameter to stop the simulator trying to calculate what should happen next. > Pushing things further, are there any applications which would (in > addition) > show the flight path given X, Y and Z coordinates in the datafile - > similar > to the computer recreations of flight data recordings? OK, this is a bit trickier, but still possible. You're X,Y,Z information should be latitude, longitude and altitude. If you then replay the flight within the multiplayer environment, and have an account on http://fgfs.i-net.hu/, you will be able to visualize the flight path on a google-maps mashup, for example: http://fgfs.i-net.hu/modules/fgtracker/index.php?FUNCT=FLIGHT&FLIGHTID=5024 Hope this helps. The I/O sub-system is under-utilized and therefore under-documented, so if you get stuck, please post to the list. -Stuart ___________________________________________________________ The all-new Yahoo!
