zono - zonohedra from OFF files
zono [options] [input_file]
Make a polar zonohedron, or a zonohedron based on the vectors from an
OFF file.
- input_file
- input file in OFF format, or if not given the program reads from stdin
- -h
- program help
- -m <mthd>
- method to create star from input, can be
- v - centre to vertices are vectors (default)
- a - all vertex to vertex are vectors
- e - edges are vectors
- -c <cent>
- centre of points for method v (default: centroid)
- -s
- output the star (instead of the zonohedron)
- -a <ang>
- discard vectors within an angle of an existing vector
(default: 0.01 degrees) if 0 don't discard vectors
- -k
- keep length of vectors (default makes them unit length)
- -P <num>
- polar zonohedron with given number of vectors
- -o <file>
- write output to file, if this option is not used
the program writes to standard output
A medium sized polar zonohedron
zono -P 50 -o polarzono.off
A rhombic triacontaahedron
unipoly icosahedron | zono -m v -o rh_tri.off
The program is fine for polar zonohedra.
It is very incomplete zonohedra made from vectors taken from a
file. It is unoptimised and can handle, at best, only a few
vectors in the star.
