zono - zonohedra from OFF files

Usage    |    Examples    |    Notes

Usage



Usage: zono [options] [star_file] 

Make a zonohedron or add zones to a convex seed polyhdron. The zones are
created from a star of vectors, which can be based on a polyhdron (input
model and option -m) or initialised (option -P) to make a polar zonohedron.
If input_file is not given the program reads from standard input

Options
  -h,--help this help message (run 'off_util -H help' for general help)
  --version version information
  -m <mthd> method to create star from input, can be
               v - centre to vertices are vectors (default)
               a - all vertex to vertex are vectors
               i - implicit edges (face sides) are vectors
               e - explicit edges are vectors
  -c <cent> centre of points for method v, C for centroid (default: 0,0,0)
  -s        output the star (instead of the zonohedron)
  -S        seed model to add zones to, must be convex
  -u        make vectors unit length
  -C <col>  colour for new zone faces
  -P <star> polar zonohedron from ordered star, can be an offset polygon
            given as an integer or fraction (e.g. 5, 7/2) or 's' to use
            star_file
  -o <file> write output to file (default: write to standard output)


Examples

A largish polar zonohedron
zono -P 50 | antiview


Rhombic triacontaahedron
zono ico | antiview


Non-Archimedean truncated octahedron
zono -m i ico | antiview


Archimedean truncated octahedron
zono -m i -u ico | antiview


Make a unit star from tetrahedron vertices and use to add red zones to a dodecahedron
zono -S ico -u -C red tet | antiview


Notes

Option -S implements George Hart's Zonish polyhedra.
