  In case 1 you are creating a box on the xz plane and applying the
function pattern directly to it, ie. the function pattern is being
read from the xz plane.

  The heightfield, however, is created on the xz plane but its height
is read from the xy plane.

  I think that in case 2 you have to call the function in the same way
as you are calling it for the boxes in that case, ie. not
"Fn_Pattern(x+X,z+Z,y)" but "Fn_Pattern(x+X,y+Z,z)"
