    1 Imho you can take out even more if you respect the equidistant nature of the Grid. (up - down) will lead to 1 component being 0, because they have equal X coordinate, and another component being 2*d where d is the Grid distance. The same goes for left-right. The 2*d factor can be left out, as you normalize anyway, so the normal should be something like (left.Z - right.Z; up.Z - down.Z; 2*d).normalize().
