i've followed this exactly to the letter, and some appear side by side and some diagonally. i've inverted θ and φ in the above 2 equations and some appear on above the other. but not all. I've doble checked and all my calculations are exactly as your's including the θ and φ.

comment move a point up and down along a sphere
@user1551 i failed to mention it works ok for XZ first quadrant where x and z are positive for both y negative or positive. The problem I get is when i move to other XZ quadrants where one or both are negative, in this case it starts to swirl around moving to the sides instead of just up and down.

@user1551 : ty I've done this and changed the φ(arctan(y/x)) value increasing and decreasing it. It work nice, but only for the first quadrant, how do I change it to work for all quadrants.

ok that is a good point, but it will not happen because it's a globe representing countries the poles will not be selected. Sorry for not explaining correctly the situation.
