Hi Melchior. This is good stuff. I've changed my automated script for placing the runway distance remaining signs to use this apparatus. It works fine in principle, but I've run into a problem (bug? dunno.).
I would naively expect the angle that you give the sign to correspond to
the orientation of a normal either going out of the sign face or going
into the sign face. However, there seems to be an offset between the
angle used and the heading of the sign face. If that offset were constant,
I could handle that no problem; but the offset seems to vary from place to
place.
For example, add the following lines to Objects/w080n30/w078n38/1679411.stg :
OBJECT_TAXI_SIGN [EMAIL PROTECTED] -77.037660 38.846302 4.92 175.51
OBJECT_TAXI_SIGN [EMAIL PROTECTED] -77.037660 38.846303 4.92 355.51
OBJECT_TAXI_SIGN [EMAIL PROTECTED] -77.035431 38.852539 4.97 142.76
OBJECT_TAXI_SIGN [EMAIL PROTECTED] -77.035432 38.852539 4.97 322.76
(these are simulating two-sided signs; more on that in a bit)
Then start up fgfs at airport KDCA and runway 15. You'll see the lower
"signs" ahead to your left. Close inspection will show that they're
almost, but not quite, aligned with the runway, despite the fact that
the signs were placed using the heading of the runway in apt.dat.
Now head off to runway 1. Ahead a little bit, on the left, one will
find the upper signs above. Here again, they're placed with angles
corresponding to the heading of the runway. However, in this case,
the signs are 90 degrees from the correct orientation -- they point
towards the runway side.
Am I missing something?

P.S. I hope you get the chance to make the surrounding sign casing/
structure/box/whatever for these signs. If/when you do, consider
the fact that the runway distance remaining signs are almost always
double-sided. One can simulate that like I do above, but that won't
work well when the physical sign is rendered (rather than just doing
a plane) -- the physical signs will overlap in the scene. Maybe
some way of specifying the surfaces of a two-sided sign in this
formalism would be good.
Thanks muchly.
