EXTRA: spidron - spidronise a polyhedron

Usage

Usage: spidron [options] [input_file]

Read a file in OFF format and convert to model built from spidron units.
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
  -l <len>  unit length, half the number of triangles from edge to centre
  -t <type> folding type, 1 - spidronmyd (default)
  -a <ang>  angle of first triangle (default: 30)
  -b <ang>  angle of second triangle (default: two times angle of option -a)
  -p <pat>  folding pattern, a series of 0's and 1's, to old in or out
            (default: 01)
  -o <file> write output to file (default: write to standard output)

Examples

spidron dod | antiview -v 0.01

spidron dod -a 60 -b 72 -p 1 | antiview -v 0.01

spidron dod -a 72 -b 60 -p 1 | antiview -v 0.1

off_color dod -e P -m map_red:orange:white | spidron -a 60 -b 72 -p 1 | antiview

Notes

The program does not include the spidron-nest construction.

Spidron units are coloured according to the colours of the corresponding edges on the base polyhedron.
