Given a normal Voronoi diagram made by lines/faces we introduce the concept of incompleteness that restricts the number of chosen lines/faces through a random process. After this operation we develop the concept of thickness after which the lines/faces loose their mathematical behavior. The developed techniques are then used to produce isodensity contours in the distribution of the galaxies similar to those deduced from the observations like the QDOT survey or latitude/longitude slices like those observed at the CFA.
