=head1 DESCRIPTION
|
||||
|
||||
Creates a contiguous sequence of points at a specified height that make
|
||||
up a horizontal slice of the edges of a space filling truncated
|
||||
octahedron tesselation. The octahedrons are oriented so that the
|
||||
square faces are in the horizontal plane with edges parallel to the X
|
||||
and Y axes.
