Voronoi diagrams I see have few if any hexagons (use your favorite mathematical reference or image search). Is that idea that if the points are distributed equidistant in 'alternating' ranks [0], then the diagram is hexagons?

Also, what is "binary breakup" and "binary fracture"?

[0] Alternating ranks: I mean something like the following (is there a better name?):

  .   .   .   .   .   .
    .   .   .   .   .   .
  .   .   .   .   .   .
