Of course I won't expect you to commit to adding any code I write,
sight unseen and untested. As long as I know there is support for the
idea from those maintaining that code and no one is against it I'm
comfortable putting in the time. The project(s) I'm working on are for
the community though, meaning they are and will be distributed freely
to all users...so of course the functionality would need to be a core
part of flightgear to be at all useful. But yeah, don't expect you to
totally commit to adding something that doesn't yet exist...

The major project I'm working on at the moment is the custom scenery
for Innsbruck. And by custom scenery I don't mean just some airport
models and a few landmarks and putting them in the db. I'm talking
about a full fledged, highly detailed, very complex and complete
scenery package...roads, highways, power lines, entire villages and
cities accurate to real life. Think along the lines of something you
expect from a payware scenery add on in one of those other flight
sims. A lofty goal yes, but I'm confident in my abilities to achieve
it as time permits, and have already committed more than a year to get
to the current point.

However to achieve such a goal, on such a scale, I'm really having to
work outside the box. The standard and accepted flightgear way of
single objects in ac3d format submitted to the database just won't
work for this type of project. I am designing and modeling very large
static geometries that  fit to the terrain accurately. While ac3d
format works 'ok' for simple models and techniques...it does not scale
well for very large and detailed objects. The file size alone is a
drawback, along with export times, load times....and the fact it
doesn't support basic things like multiple texture coordinates /
texture units. So what I really need, and what would benefit
flightgear as a whole in long term, is a fairly efficient binary
format that supports such features. Of course we can already load
these formats and use them, and I am as best I can, but they aren't
fully supported by flightgear yet as they could be / need to be. The
classic flightgear xml material animations for example doesn't know
anything about multiple texture coords, texture units, and so on...so
we need (and prefer anyway) the modern material effect and shader
support system you've designed in order to use these formats and
features properly.

Well, I feel I'm rambling on a bit again, but I hope that it at least
makes it somewhat clear what I'm trying to achieve and why, and why I
need the functionality I'm looking for. You can check my Innsbruck
thread in the scenery section of the forums if your interested in
details, methods, techniques, and tools I'm exploring for this...or
just ask.

Thanks Tim, I will be diving in so expect some questions and such in
the near future. ;-)

thanks...cheers!
