version version information
a <ax,p> axis order. may be 0, 1 or 2 (default 0) (multiple a as needed)
p is percent length of the axis. (default 100 percent)
f <list> specify a list of elements, list starts with element letter,
followed by an index number list, given as index ranges separated
by commas. range can be one number or two numbers separated by a
hyphen (default range numbers: 0 and largest index).
Index number list will be preceded by f, e, v for faces, edges and
vertices. Elements resolve to connected faces to be staring point
for radial coloring. special selector: s for number of face sides
(f overrides a, multiple f as needed)
s <sym> symmetry subgroup (Schoenflies notation)
A <opt> show axes used. points=1, axes=2 (default: none)
l <lim> minimum distance change to terminate planarization, as negative
exponent (default: 12 giving 1e12)
o <file> write output to file (default: write to standard output)
Coloring Options (run 'off_util H color' for help on color formats)
T <tran> face transparency. valid range from 0 (invisible) to 255 (opaque)
m <maps> color maps for all elements to be tried in turn (default: rng)
n <maps> map name for axes 0, 1 and 2 (default: map_red:yellow:darkgreen)
Color faces of a geodesic sphere symmetrically in radial bands
Also display symmetry axes with A
off_color e white v white geo_7_4_d  radial A 2  antiview v 0.01
Color a figure from conway notation from faces 0 and 3
conway a^5C  radial f f0,3  antiview x ve
radial was written by
Roger Kaufman.
Radial colors bands of color eminating from radial points on the
model. It can color from symmetry axes or chosen faces. It can
also display symmetry axes as part of the model.
