kcycle - kaleidocycle rings of polyhedron
kcycle [options] [hinge_vertex_idxs]
Create a stage of a kaleidocycle rotation in OFF format. A kaleidocycle,
using the term generally, is a symmetric ring of polyhedra, each
polyhedron joined by two hinges.
- hinge_vertex_idxs
- Four numbers separated by commas. The first two numbers specify the
first hinge. They are the index numbers (starting from 0) of the
vertices of the hinge, which will normally be an edge of the
polyhedron. The third and fourth numbers specify the
second hinge (default: only if option -i not used, 0,1,2,3).
- -h
- program help
- -a <ang>
- angle in degrees to rotate the first hinge from horizontal (default: 0.0)
- -n <num>
- number of pairs of polyhedra in cycle (default: 6)
- -i <file>
- input file in OFF format. If '-' then read file from stdin.
(default: a tetrahedron with hinge_vertex_idxs 0,1,2,3)
- -o <file>
- write output to file, if this option is not used
the program writes to standard output
Tetrahedron kaleidocycle rotated 40 degrees from horizontal
kcycle -a 40 > kc_tet_90.off
Ring of 16 icosahedra, each given a proper coloring, rotated 90 degrees,
and displayed in antiview
unipoly ico | off_color -f P | kcycle -i - -n 8 -a 90 0,1,10,11 | antiview -v 0.1
The ring has coinciding vertices. To display the vertices or edges
in antiview or off2pov their size must be set manually
using options -v or -e
