fe6ff15206 Remove --min-angle option. 2003-08-19 02:36:10 +00:00
curt
730c454320 - Test a different approach for assigning land cover attributes to "default' 
cover" areas.  Rather than artificially cut in polygon areas, just lookup
  a land cover type for unassigned triangles.  I think this has potential, but
  it needs more work to eliminate some odd artifacts.

- Revove --min-angle= option.

- Don't re-fit() triangle array to try to achieve a particular range of
  node quantities ... this is all pre-computed with a much smarter, much
  more efficient algorithm.

f5f961b8c0 Remove support for a "minimum triangle angle" quality constraint when 
triangulating a tile.  A better strategy is to have better input that doesn't
need to hide behind this trick.

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

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

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.

b3935db989 Add back code to clip polygons against land mass. This temporarily breaks 
the ability for roads/railways to bridge ocean, but I hope to get that fixed
soon.

1a46456fbd Use .arr as the intermediate height field rather than .dem since .dem 
implies a different format.

c0b4508955 - fixes to support clamping to a small grid (improves triangulation)
