From http://lists.trolltech.com/qt-interest/2002-09/thread01124-0.html :

does anybody here have an algorithm to calculate the normal vector in a given point in space (x, y, z) in a sphere? I know that it's not about qt but i'll like very mutch the help.

It's simply the connecting vector from the centre of the sphere to the point (other way around for inward normals) obtained through vector subtraction, normalized to unity.

You really should get an algebra book though, as you are bound to encounter more of these problems in a 3d application.
