December 7 2003 12:20:35.566 PM CVT_MOD_DATASET Create CVT datasets. (real arithmetic) CVT = Centroidal Voronoi Tessellation. The computational region is the unit hypercube. Opposite boundaries are identified, yielding a topology similar to a torus. Given a region in ND, the problem is to determine GENERATORS, a set of points which define a division of the region into Voronoi cells, which are also CENTROIDS of the Voronoi cells. :># cvt_mod_02_00010.inp # :>:> SEED = 123456789 :>:># The generators were initialized by UNIFORM. :> Sampling function is UNIFORM. :> Geometry parameters: ------------------- The spatial dimension is M = 2 The data lies in the unit hypercube [0,1]^M.
