polygon - polygon based polyhedra
polygon [options] num_sides
Make polyhedra based on polygons: polygons, prisms, antiprisms,
pyramids, dipyramids, cupolas, orthobicupolas, gyrobicupolas.
- num_sides
- a number (N) optionally followed by / and a second number (N/M).
N is the number of vertices spaced equally on a circle, then each
vertex is joined to the Mth (default: 1) vertex moving around the circle
- -h
- program help
- -t <type>
- polyhedron type, can be polygon, prism (default), antiprism, pyramid
or dipyramid. Type can be abreviated to three letters.
- -e <edge>
- length of polygon edge (default: 1)
- -R <rad>
- circumradius of polygon (default: use -e)
- -r <rad>
- inradius of polygon (default: use -e)
- -l <hgt>
- height of upper vertices above base polygon
(default: circumradius of polygon
- -E <len>
- length of non-polygon edges (default: use -l)
- -o <file>
- write output to file, if this option is not used
the program writes to standard output
A cube with edges of 2 units
polygon -t pri -e 2 -l 2 -o cube.off 4
A hexagonal based pyramid
polygon -t pyr -o hex_pyramid.off 6
A uniform pentagrammic antiprism
polygon -t ant -e 1 -E 1 -o pent_anti.off 5/2
A uniform pentagrammic crossed antiprism
polygon -t ant -e 1 -E 1 -o pent_cross_anti.off 5/3
