How to generate a subdivided icosahedron?

Question

I've asked some questions here and seen this geometric shape mentioned a few times among other geodesic shapes, but I'm curious how exactly would I generate one about a point xyz?

Answer 1

There's a tutorial here.

Answer 2

Here is one reference that I've used for subdivided icosahedrons, based on the OpenGL Red Book. The BSD-licensed source code to my iPhone application Molecules contains code for generating simple icosahedrons and loading them into a vertex buffer object for OpenGL ES. I haven't yet incorporated subdivision to improve the quality of the rendering, but it's in my plans.
