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.
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.
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.
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

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
