Usage



Usage: off_color_radial [options] [input_file]

Color in radial pattern based on symmetry.

Options
  -h,--help this help message (run 'off_util -H help' for general help)
  --version version information
  -l <lim>  minimum distance change to terminate planarization, as negative
               exponent (default: 12 giving 1e-12)
  -o <file> write output to file (default: write to standard output)

Scene Options
  -d <opt>  coloring. radial=1, axes=2 (default: 1)
               (multiple -d as needed)
  -a <ax,p> axis order. primary=1, secondary=2, tertiary=3, all=4 (default: 1)
               p is percent length of the axis. (default: 100 percent)
               (multiple -a as needed)
  -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
               (multiple -f as needed, -f overrides -a)
  -s <sym>  symmetry subgroup (Schoenflies notation)

Coloring Options (run 'off_util -H color' for help on color formats)
  -E <col>  edge color (default: unchanged)
               keyword: none - sets no color
               f - color with average adjacent face color
  -V <col>  vertex color (default: unchanged)
               keyword: none - sets no color
               e - color with average adjacent edge color
               f - color with average adjacent face color
  -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)
              rng and rainbow maps without entries specified are calculated 
  -n <maps> color maps for axes (A=1: calculated, A=2: map_red:blue:yellow)
  -A <opt>  color axes by nfold=1, order=2 (default: 1)

Examples

Color faces of a geodesic sphere symmetrically in radial bands Also generate symmetry axes with -d axes
off_color -e white -v white geo_7_4_d | off_color_radial -A 2 | antiview -v 0.01


Color a figure from conway notation from faces 0 and 3
conway a^5C | off_color_radial -f f0,3 | antiview -x ve


Notes

off_color_radial was written by Roger Kaufman.

Colors by 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.
