EXTRA: dome_layer - dome strut arrangements
Usage: dome_layer [options] [input_file]
Read a dome polyhedron in OFF format, project onto unit sphere and add
additional layering. 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
-r <rad> radius of sphere for second layer vertices (default: 0.85)
-t <type> layer type (default: dual)
dual: base vertices to dual vertices
eden: base vertices to edge centre vertices
asm: base vertices to inner base, vertices to cell centres
honeycomb: base vertices to dual of 'kis' form
prism: repeat base and connect faces as prism tensegrities
-i write colours as index numbers (struts 0-4, faces 10)
-o <file> write output to file (default: write to standard output)

The source of the Eden, Dual ASM and honeycomb patterns was Tim Tyler's
Springie Gallery. The prism
tensegrity pattern is based on a model held by Fuller in a photograph
and discussed on the
Geodesic Help Group.
