cvt_circle_nonuniform, a MATLAB code which demonstrates the computation of a centroidal Voronoi Tessellation (CVT) over a circular region, using a nonuniform density.
As you watch the CVT develop, for instance, you will be able to guess something about the angle of intersection between the boundaries of the region, and the edges of Voronoi regions.
CVT_CIRCLE_NONUNIFORM is a MATLAB function for computing a CVT in a circle with a nonuniform density. The spatial region is the unit circle, but a nonuniform density is applied to that region. The density is implicitly defined by the sampling routine, which returns many more points near the circumference than near the center of the circle. The result is that, during the CVT iteration, the generators arrange themselves more densely towards the outer part of the circle.
[ p, t ] = cvt_circle_nonuniform ( n, sample_num, delaunay_display )
