delaunay — constructs the constrained Delaunay triangulation of the input


delaunay [Options] < file.gts


This manual page documents briefly the delaunay command. This command constructs the constrained Delaunay triangulation of the input


This program follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below.

Do not keep convex hull.
Do not add constrained edges.
Split constraints (experimental).
Remove holes from the triangulation.
Remove duplicate vertices.
Shuffle input vertex list.
Check Delaunay property.
-f FNAME, --files=FNAME
Generate evolution files.
Generate conforming triangulation.
-s N, --steiner=N
Maximum number of Steiner points for conforming triangulation (default is no limit).
-q Q, --quality=Q
Set the minimum acceptable face quality.
-a A, --area=A
Set the maximum acceptable face area.
Print statistics about the triangulation.
Display the help and exit.
