FLOW CHART for source code

Postby mike4lin » Tue Aug 09, 2011 3:35 pm

I miss a plan where to find anything. A simple FLOW CHART where all major features can be found within the code.
Myself I wonder how i could implement x-plane 9 airport format, ie how to upgrade the existing 8 format to 9. Still have not even found the relevant code
for such after two days or so.

I was attempting to do this myself, but I have little time and it might take more than one brain.. I'm sure you know where to find the X-Plane data and changelogs, so take a look in FlightGear/src/Airports; specifically apt_loader.cxx

Yes that's the parser which is even up to date to the newest apt.dat format. But I'm looking for where the airports are drawn.

You shoud search in the terragear code. That's what generates the scenery ground model (airports included). Flightgear only displays what is already pregenerated.

Check out the developers portal on the FlightGear wiki (http://wiki.flightgear.org). There is *tons* of great info there, covering many many many subjects. If you don't find something there that you really need, consider helping us out and adding it.

A neat tool a friend turned me on to, for Charting Flow. It does so in ASCII characters making the chart easy to share in text files.

That's correct, some info on the underlying file format can be found here: http://wiki.flightgear.org/BTG_file_format

I am afraid, the architecture of TerraGear itself is pretty undocumented at the moment.
But if you know C++ you can probably get started just by looking for main() and proceeding from there.

In addition, you could consider running doxygen against the terragear source tree to create some flow charts automatically.
Also, you might want to check out "SourceNavigator NG" for navigating the source tree.

Personally, I'd suggest to start a new wiki page and put your questions there and collect your findings - so that others can try to help you, you may also want to check out the FlightGear developers mailing list to ask your questions there.

In addition, it'd be a good idea to search the archives of the mailing lists and the forum for possibly related information.
Please don't send support requests by PM, instead post your questions on the forum so that all users can contribute and benefit
Thanks & all the best,
Hooray
