Ant,

Your code did not work as I thought, I made some minor changes and not it works like a dream. There is still work to be done as I need to calculate the centre of mass before calculating the map.

Code as is

Function SphereMap( spX#,spY#,x#,y#,U:Float Var,V:Float Var )
        xd# = x - spX
	yd# = y - spY
	mag# = Sqr(xd*xd + yd*yd)
	xd = xd / mag
	yd = yd / mag
	u = (xd/2) + 0.5
	v = -(yd/2) + 0.5
End Function
