#################
The hgrd code was created for triangulation of a polygon of any shape. It can also
triangulate many separate polygons in one pass.
Program was tested with gcc 2.95, MS Visual C++ 6.0 and 7.0 compilers.
2005-07-28:
in order to use newer versions of gcc without generating warnings the definitions
of friend operators inside vect.h has been modified
USAGE
=======
A makefile is written for gnu make and can be used for compilation under Linux/Unix
platforms with gcc compiler.
A command line for running the program is following:
hgrd [file with points] [output tecplot file]
e.g.:
hgrd simple_poly.pnt output.dat
INPUT FILE
============
The polygons are defined in a file as a list of closed boundaries. The direction
in which points are entered determines if the boundary encloses a hole or a polygon.
It is supposed that polygon lies on the left side of the boundary.
Sample input file :
2 <--- number of closed boundaries
13 <--- number of points in first boundary
0 0 <--- x and y coordinates of a point
1 0
1 0.6
1.5 0.6
1.5 0.3
2 0.3
2 0.9
0.6 0.9
0.6 1.3
1 1.3
1 1.5
0 1.5
0 0
5 <--- number of points in second boundary
0.2 0.2
0.2 0.7
0.8 0.5
0.8 0.2
0.2 0.2
OUTPUT FILE
============+
The output file is a file used for Amtec Tecplot visualization software.
TITLE = "polygon"
VARIABLES = "X", "Y"
ZONE T="TRIANGLES", N=41530, E=38849, F=FEPOINT, ET=TRIANGLE C=BLACK <--- N is number of nodes E is number of elements
594.861 2854.66 <--- X and Y coordinates of a point
595.035 2854.4
595.559 2854.15
...
595.355 2854.56
219.187 2057.75
