cvtp
cvtp,
a FORTRAN90 code which
creates CVTP's, that is, Centroidal Voronoi Tessellations
of a periodic region.
A 2D unit logical torus is the unit square, but with "wraparound".
This is the connectivity frequently seen in video games, in which
a spaceship flies off the top of the screen and immediately reappears
at the bottom of the screen. In the general M-dimensional case,
the extreme minimum and maximum values of each coordinate are
identified, and modular arithmetic may be used to determine
distances.
