UNSUPPORTED: dome_layer - dome strut arrangements

Usage    |    Examples    |    Notes

Usage



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)


Examples

Eden "in"
dome_layer -r 0.9 -t eden geo_2_1_d | antiview -x f -v 0.02


Eden "out"
dome_layer -r 1.1 -t eden geo_2_1_d | antiview -x f -v 0.02


Dual "in"
dome_layer -r 0.9 -t dual geo_2_1_d | antiview -x f -v 0.02


Dual "out"
dome_layer -r 1.1 -t dual geo_2_1_d | antiview -x f -v 0.02


ASM
dome_layer -r 0.9 -t asm geo_2_1_d | antiview -x f -v 0.02


"Honeycomb" "in"
dome_layer -r 0.9 -t honeycomb geo_2_1_d | antiview -x f -v 0.02


"Honeycomb" "out"
dome_layer -r 1.1 -t honeycomb geo_2_1_d | antiview -x f -v 0.02


Prism tensegrity sphere, colour "struts" red and all "strings" white
dome_layer -t prism -r 1.3 -i geo_2_1_d | off_color -e M -m map_red:white:white:white | antiview -v 0.02


Notes

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.
