voronoi_plot, a MATLAB code which plots the Voronoi neighborhoods of a set of center points.
The picture is created using discrete pixel geometry, rather than sophisticated analysis. In other words, each center point is assigned a color at random. Then each pixel in the image is colored the same as the nearest center point.
The program allows the user to choose the values of M and N, the number of rows and columns used in the pixel array.
The program allows the user to choose the LP norm in which distances are calculated, with P any positive real value. In particular
MATLAB's voronoi() command can plot a Voronoi diagram when the Euclidean norm is used to measure distance, but it does not have the ability to deal with other norms. This program gives a simple way of viewing such cases.

voronoi_plot is available in a FORTRAN90 version and a MATLAB version and a Python version.
sphere_delaunay, a MATLAB code which computes the Delaunay triangulation of points on a sphere.
sphere_voronoi, a MATLAB code which computes the Voronoi diagram of points on a sphere.
voronoi_mountains, a MATLAB code which makes a "mountain plot" of a Voronoi diagram, that is, a surface plot of the distance from each point to its nearest Voronoi generator.
