Question

I’m not looking for a library or even open source code. I want to learn how to do this on my own.

Where do I start to find an online tutorial, a book chapter, or other educational material for generating a polygonal model of a 3D sphere suitable for feeding to Open GL ES on an iPhone, and then mapping the polygons to some sort of 2D map data so I can texture map the sphere? Is there some sort of software tool (blender? maya?) with a tutorial on how to do generate this data? Where is the best place to start?

How about these articles?
