# Hexsphere Generator
Eventually, this will be a full-blown planet generator. But, for now, this is a
hexsphere generator. This shape is also known as a [Goldberg
polyhedron](https://en.wikipedia.org/wiki/Goldberg_polyhedron) or a [truncated
icosahedron](https://en.wikipedia.org/wiki/Truncated_icosahedron). It is made
from generating a [icosahedron](https://en.wikipedia.org/wiki/Icosahedron) which
is split N times for a detail level of N. The [dual
polyhedron](https://en.wikipedia.org/wiki/Dual_polyhedron) of that shape is
calculated which results in the hexsphere. In its smallest form (detail level of
0), it has 12 pentagon faces. As the detail level increases, it gains more
hexagon faces and becomes more spherical in shape.
