<pre wrap="">Dear Scilab friends,
I have 15,000 points in 3d space with known xyz Carthesian coordinates and the basic question is, if their arrangement is random or not.
I had been suggest to do Voronoi tessellation/ Delaunay triangulation. The famous problem of the location of the nearest public phone, but this is only 2d.</pre>

The CGAL module has a 3D Delaunay function available for Scilab 6:<br>
