f20966c21c Increase RLIMIT_CPU to 12h (from 5mn) in fgfs-construct. I have never witnessed the infinite loop that this limit is supposed to catch - however complex tiles frequently require more than 5 minutes CPU. 2011-10-24 11:26:41 +02:00

b0a47dfa0e Ron Jensen: 
Dirt and grass runways are generated by GenAirports/rwy_simple.cxx.
The runways are divided into two halves, "A" and "B" each consisting of
two triangles.
Runway half "A" is good.
Runway half "B"'s first triangle UV coordinates are a very short line,
and its second triangle's UV coordinates are a point.

[...]

[T]his patch does the Right Thing.  It simply changes the reference
point so the UV coords for the B runway are positive.  They were coming
out negative and getting clipped in build.cxx.

01ba584d2e OVERVIEW: 
For the time being of VMap0-data in FlightGear Scenery, there have been
two cases of simplification, where different types of landcover usage
have been stuffed into the same TerraGear work directories:

1.) VMap0 "Glacier" and VMap0 "Polar Ice" have been accumulated in the
    'LandCover/Glacier' directory,
2.) VMap0 "Wet Sand" and VMap0 "Marsh" have been mapped together in
    'VPF-LandCover/Marsh'.

These have been defined in the 'TGVPF/process.sh' for a long time and
we simply ported the identical mapping over to 'ShapeFile/process.sh',
in order to provide an exact image of what had been done previously
with the TGVPF reader, when we did all those funny ShapeFile thingies.

When I started storing all the landcover data in a PostGIS DB, one goal
I had in mind was to understand and clean up the structure of all those
different layers.

Now, after many hours of reading VMap specs and dealing with this data,
I have come to the point where we could merge VMap1 data into the VMap0
stuff where VMap1 is available and I'd like to have those duplicates
cleaned up before we're getting into an even bigger mess.

This means, and this is what the patch implements, that we're going to
handle "Polar Ice" landcover data separately from "Glacier" as well as
"Wet Sand" (which apparently means "Littoral" in our case) separately
from "Marsh" - in TerraGear. In order to let FlightGear behave the same
as previously, the two mentione mappings are now implemented by
respective additional "name" entries in the 'materials.xml' file. I
already committed these entries.

I'd like to progress with the task of adding improvements to our
landcover data set because I consider it as one of the vital goals of
further development to add more and more diversity to The Scenery. So
I'm eager to see these really small but significant issues resolved.

7de22d8ef2 tgChopPolygon() called a really simplistic polygon partitioner for large 
polygons.  This was to bail us out of the overwhelming memory requirments
when using the default polygon clipping routines on really large polygons.
However, the simplistic polygon partitioner did not handle holes.
Unfortunately, several TG utilities were calling this function with polygons
that did contain holes with potentially mixed results.

I renamed this function tgChopBigSimplePolygon() and created a new
tgChopNormalPolygon() which should be used by most utilities unless you
really know what you are doing.

This has some performance implications, but achieves more correct results.

cd7ee31c7e Frequently our beloved polygon clipper will generate polygons with a wierd 
branch.  Kind of an out and back.  node[n] == node[n+2] where there is some unique point in between.  Our triangulator is usually robust to this, but not in
100% of all cases.  So I had some code to catch and eliminate this weirdness.
However, a key piece of code was commented out (?!?) rendering it a no-op.
I fixed this and tile building is more robust now.

fd0a6e29fc Ok, this change seems to help a lot. 
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.

ac461bda55 - Switch to using doubles for the nurbs library. We were running out of 
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.

791b1bb4fc David Luff: 
The patches deal with three separate issues, all rolled up into one
tarball:

Currently, arrayfit always appends .arr.gz onto the name passed on the
command line, meaning that only tile names can be passed.  The patch strips
off .arr or .arr.gz if present prior to it's appending, meaning that tile
names or filenames can be passed on the command line.

The interface to the OSGB36 conversion functions is cleaned up a lot.  I
can't believe I originally wrote it in such an ugly manner!

A lot of console output (> 5000 lines per tile) is removed from the final
construction process, meaning that the output left can actually be read.

a71d62c859 David Luf: 
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
tgvpf.

9a7173d85e For smoothing things like rivers or roads we need to allow some slope. 
Originally I through together a really cheap/ugly hack for estimating
distance between two points, but that really started to stink when throwing
a lot of new situations at it.  So now I calculate spherical distances between
two points in meters which is plenty accurate for these purposes.  This gives
us much better control over smoothing.  For instance we could establish a
maximum 10% grade for all roads if we wanted to.

Essentially start with two triangles forming the bounding surface.
Then add the point that has the greatest error.  Retriangulate.
Recalcuate errors for each remaining point, add the one with the
greatest error.  Lather, rinse, repeat.

d05fd4a8ff Big round of cascading FG -> TG name cleanups (once you get going it's hard

Also save elevations of 3d polygons into a separate lookup list when they
are loaded by the clipper.

d70cd72fbd Don't automatically try to preserve polygon elevations, but instead provide 
a method() to inherit elevations from another polygon.  This gives the calling
layer much more control over preserving or not preserving elevations.

c5ab6678f2 Added support for including height information in the intermediate polygon 
format.  The big trick was that the polygon clipper is completely 2d.  So
I needed to add code to preserve the elevations in the clipped output and
fill in plausible elevations for any new points created as a result of the
clipping.

9c85f16b5f Working towards the ability to specify elevations for a polygon in it's 
intermediate mode.  The goal then is that these elevations would be
preserved throughout the tile construction process and the surrounding
geometry would fill in without gaps.  This has potential applications for
airports and runways of course as well as roads, rivers, streams, railroads,
or any other object where we might want to control the final elevation in
advance.
