UNSUPPORTED: spidron - spidronise a polyhedron
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.

--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
-o <file> write output to file (default: write to standard output)
Default, an in out pattern
spidron dod | antiview -v 0.01
Out only, to points
spidron dod -a 60 -b 72 -p 1 | antiview -v 0.01
Out only, flaring out
spidron dod -a 72 -b 60 -p 1 | antiview -v 0.1
Colour is taken from the base model edges
off_color dod -e P -m map_red:orange:white | spidron -a 60 -b 72 -p 1 | antiview
The spidron program makes spidron pyramid-style models based on
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.
