favor of newmat11 which is much simpler, and seems to compile well on modern
OS's.) I need to do some further testing of genapts and until then, don't
assume the new mechanism is working perfectly.
situations
- Made the code a bit more robust and able to handle the handful of rare
occasions when the least squares nurbs interpolator fails.
- Add airport surface bases for towers, windsocks, beacons, and vasi/papi
lighting so they never are buried and never float. (I'm considering the
idea of doing this for the approach lighting too ...)
surface. I think I have this working robustly.
A few miscellaneous tweaks to handle latest X-Plane data (with a few new
runway surface codes we hadn't seen before.)
There are quite a few difficult cases where an airport is located on top
of a hill, or in a bowl, or has a significant elevation change near by.
I take the average elevation of the area and clamp the outlyers. However
these difficult cases "bias" the average elevation because the airport
surface may include much of the surrounding area.
This change to the code computes the airport elevation *only* based on the
actual airport geometry node and ignores all the surrounding nonsense that
might exist. This doesn't make things perfect, but is a *big* step forward
for airports in areas with significant elevation change nearby.
precision with floats.
- Restructure how the airport surface is sampled just a bit.
- Solving for X,Y given U,V on a nurbs surface is a little bit tricker than
I first thought. If you change one demension of U or V, you can change
both X and Y. We need to solve for each X, Y axis independently, and
then iterate in case moving in the other axis has taken us away from the
solution in the first axis.
- Add a slope constraint on airport surfaces.
Expose a polygon function that will split up long edge lines to keep the
max edge distance below some threshold. This could be used for instance
to reduce long lines in polygon area shapes so they can better follow
the underlying terrain changes.
The attached patches significantly quieten the output from genapts, which in it's current form resembles the universe flying by on a bad hair day Remember chaps, console output on Windows is slooowwwwww... Normal service may be resumed using --verbose or -v. I've also added a short help, obtainable with --help or -h. I've also added a couple of extra options, --airport=abcd for just generating a particular airport, and --tile=<[we]xxx[ns]xx> for generating a 1x1 degree tile. We currently have --chunk=<[we]xxx[ns]xx> for generating a 10x10 degree chunk, and I'd like to eventually add --tile as an option to all tools that take --chunk.
This one adds the tile option to

Erik Hofman:
Some small code changes for IRIX.
Before:
- if it's a concrete taxiway over 150 ft wide, assume it's an apron
(confusingly called "tiedown")
After:
- if it's an asphalt or concrete taxiway over 150 ft wide, *or* if
it has no blue taxiway lights, assume it's an apron
markings.
- Fix a couple very small alignment/sizing problems.
- Use a different texture (similar to rest) before aim points on nonprecision
runways. This will potentially make things easier if we want to add
skid marks to the textures.
- Fix a couple bugs (el stupido) in precision marking generation.
on the command line with the --terrain= option. You can specify as many as you like. Directories specified on the command line will take precidence over
the default directories and the directories will be searched in the order
specified.
in Robin's data.)
- Code adjusted to work with slightly modified input data format (part of
our move away from metakit.)
- Eliminate some debugging output.
Attached are patches to Terragear to enable it to compile out of the box on
Cygwin (once all the relavent libraries have been compiled). Specifically
they fix a conflict with another version of min/max somewhere on the
system.
