I'm working on a project involving the creation and modeling of a planet. The planet is described via hexes, with 1 hex at the north pole and and one at the south pole. The problem is that assuming a linear progression of hexes down to the equator (no. of hexes=belt*6, except for north pole and south pole, where it is 1 hex), how can I realistically model the fact that if you put a person on the surface and tell him to walk north continually, that he will arrive back at where he started? There seems to be no real easy way to do that--a consisten algorithm for determining the "northern" hex from where he is standing does not seem possible. Also, another problem is that if you are in the first band of hexes and continually walk east, you won't come back where you started, as you should. Does anyone know of an easy way around this? Thanks, Brian
