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)
