Usage: jitterbug [options] [cycle_stage] Create a stage of the jitterbug transformation in OFF format. The cycles run from 0.0 to 1.0. The fractional part of cycle_stage is tied to a stage in a full rotation jitterbug. This stage is measured by the distance travelled by a point moving around a square which halves a cube of edge 0.25, and which determines the jitterbug shape. Options -h,--help this help message (run 'off_util -H help' for general help) --version version information -f <fces> faces to include: x - none a - all e - equilateral triangles (default) o - other triangles -c <cyc> cycle type: f - full rotation o - alternating between left and_ang(cyc_val) right octahedron stages r - rolling between left and right octahedron stages i - alternating between left and right icosahedron stages -l <size> lattice size, nummber of jitterbugs along an edge (default 1) -r allow lattice reversal by fixing connections between jitterbug neighbours -t fix an opposing pair of triangles, stopping them from rotating -T rotate so equilateral triangle is on top (suports -t) -o <file> write output to file (default: write to standard output)
jitterbug -f e 0.125 > jb_oct.off
jitterbug -c i -l 3 0.75 > jb_ico.off
The equilateral faces are given colour index 1, and the other faces
have colour index 2. The faces can easily be given colour values
using the off_color program. E.g.
jitterbug -c i -l 3 0.75 | off_color -c 2 > jb_ico_col.off
