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.
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.
- Put a space between arguments and redirection operator: looks nicer
and may be necessary in some circumstances.
- Add missing option "--min-angle" to help text.
(These are not yet enabled by default because we haven't addressed what
happens when snapping a hole boundary, but not the original object to
fit in the hole.)
Fixed a bug in triangulating that was potentially overwriting other
memory when creating the hole list to pass to the triangulator. This
fixes a lot of glitches!
fgfs-construct and fgfs-tools-client. The option takes an argument giving
the location of the land-cover raster file; if it is not specified,
land-cover is not built.
Curt tweaked the code that divides up the tile into land use squares but there
are still a couple slightly fishy things going on there.Z
The following files have been changed to enable the latest Terragear CVS
to compile with MSVC++ 5.0
.\construct\clipper\clipper.cxx
for( int i - lots of places
.\construct\genoutput\genobj.cxx
fix directory logic for windows, line 320 and following
.\construct\main\main.cxx
windows does not have an opendir function
added code for windows directory functions
disabled the mem allocation limit code - windows does not
have similar functions
for ( int i - several places
.\construct\match\match.cxx
moved the definition of file and command outside of the ifdef line 420
.\lib\e00\e00.cxx
for( int i - several places
.\lib\e00\e00.cxx
use simgear/compiler.h constructs
.\lib\geometry\contour_tree.hxx
removed a cout statement
.\lib\geometry\poly_support.cxx
added float.h changed 1.0e+999 to DBL_MAX, windows doesn't go that big
lots of for ( int i changes
lines 193 and 208 no != operator defined - changed logic
line 801 flag should be int, not bool, get_hole_flag returns int
.\lib\landcover\landcover.cxx
.\lib\landcover\landcover.hxx
add include simgear/compiler.h
see comments
.\lib\optimize\genfans.cxx
function canonify added return at end, windows complains
added using std for cout and endl
.\lib\optimize\genstrips.cxx
function tgGenStrips no return value, moved by_node into outer scope
fix for ( int i ...
.\lib\poly2tri\construct.c
added include <memory.h> for windows
remove unused variables lines 435 & 437
.\lib\poly2tri\misc.c
added HAVE_SYS_TIME_H logic for sys/time.h include file
added logic to uses windows functions for time and rand
.\lib\poly2tri\monotone.c
added include <memory.h> for windows
lines 286-288 remove unused variables
.\lib\poly2tri\tri.c
remove sys/time.h - no time functions called
added include <memory.h> for windows
.\lib\polygon\polygon.cxx
function polygon_to_tristrip will not compile I don't think the
logic is complete, no returned data added if else endif around
function and polygon_to_tristrip_old, renamed _old function.
Search of code reveals that function is not called by anyone.
.\lib\polygon\superpoly.cxx
changed include <superpoly.hxx> to "superpoly.hxx"
.\lib\polygon\superpoly.hxx
add include <windows.h> for windows before include <gl.h>
needed for definitions used in Microsoft version of opengl
.\lib\shapelib\dbfopen.c
added include files for windows
lines 195-197 271-272 515-517 removed unused variables
.\lib\shapelib\shpopen.c
added #include <stdlib.h> for malloc() and friends
added include files for windows
line 279 527 813 1127 removed unused variables

.\lib\win32\mkdir.cpp
documented function, remove debug lines
.\prep\demraw2ascii\main.c
lines 46-50 remove unused variables
.\prep\demraw2ascii\rawdem.c
line 47 changed logic to compile with MSVC
line 244-256 set real constants to float, windows complains with
double constants
.\prep\genairports\build.cxx
lots of for ( int i changes

added using std cout
.\prep\shapefile\noaa_decode.cxx
.\prep\shapefile\shape_decode.cxx
added using std for cout
lines 45-49 moved unused variables inside #if 0 block
- increased maximum areas to 128 (for future growth), and added Road
and Railroad areas
- changed the method of calculating the triangle centre in
poly_support.hxx
- added a has_holes() method to polygon.hxx
- added a new library, e00, for reading ArcInfo e00 files (i.e. the
free online ones from DCW and GeoGratis); it needs more work
- added a new prep utility, e00lines, for creating textured polygons
out of e00 line data (with user-specified width and area type); this
is useful for roads, railroads, rivers, and utility lines
Added adjacent triangle area weighting for calculating vertices of nodes.
Check for super small or degenerate triangles which could blow up our face
normal calculations.
