Hey I was hoping that I could get some quick pointers on how I would be able to do some simple functions for my next game project. [size=9px](Will start after GQ is completed!)[/size]

I'm planning to have the Earth rendered as a single 3D sphere and will need to plot locations on and around the surface. I'll also need to plot and track movement as well as determine specific zones (countries, regions, fallout areas) and day/night.

I can think of how to do it in 2D no problem, but somehow I can't wrap the idea around my head using vectors or 3D maths. :?
