Distribute points on rings a sphere.
- num_rings
- The number of rings between the poles that points will be placed on
- num_divs

- -s
- stagger placement of balls between rings
- -x
- don't place points at the two poles
- -o <file>

the program writes to standard output
A globe
sph_rings 12 24 | conv_hull | antiview
Stagger the rings on the globe
sph_rings -s 12 24 | conv_hull | antiview
As many points as will fit on the 12 rings
sph_rings 12 | antiview -v b
The output can be run through conv_hull to create a polyhedron.
