conv_hull - convex hulls (using Qhull)
conv_hull [options] [input_file]
Read an file in OFF format and make a convex hull (using Qhull).
- input_file
- input file in OFF format, or if not given the program reads from stdin
- -h
- program help
- -a
- append the convex hull to the input file
- -Q <args>
- additional arguments to pass to qhull (unsupported, may not work
check output)
- -o <file>
- write output to file, if this option is not used
the program writes to standard output
cube.txt is a file containg eight cube vertices ±1, ,±1, ±1. Make the edges with
conv_hull -o cube.off cube.txt
triangulate the output, so each square also has a diagonal edge
conv_hull -Q QJ -o cube.off cube.txt
See
Notes
below
This is a very thin wrapper around Qhull. The Packinon programs
will read three dimensional Qhull OFF output, so it is also
convenient to use the Qhull programs directly. This is
recommended if you want to use additional options. Notice that
conv_hull -Q Qt -o cube.off cube.txt
conv_hull -a -Q QJ -o cube.off cube.txt
Do not give the expected results.
