Trunacated icosahedrons (I call them hexspheres) are a bit slower to generate
since they are made by generating a icosahedron and then subdividing it into
hexagon and pentagon faces. I still have some work to do to improve that code.
hexagon and pentagon faces.
I'm still having issues rendering hexspheres of detail level 5 and higher and
icosahedrons of detail level of 7 and higher, so I'm not sure if those are
accurate.
When rendering hexspheres of detail level 5 and higher and icosahedrons of
detail level of 7 and higher in WebGL, make sure to enable the
[`OES_element_index_uint`](https://developer.mozilla.org/en-US/docs/Web/API/OES_element_index_uint)
extension since the number of vertices might overflow the normal int index.
