CVT_CIRCLE_UNIFORM
Uniform Centroidal Voronoi Tessellation on Circle


CVT_CIRCLE_UNIFORM is a MATLAB program which demonstrates the computation of a centroidal Voronoi Tessellation (CVT) over a circular region, using a uniform 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.

Usage:

CVT_CIRCLE_UNIFORM is a MATLAB function for computing a CVT in a circle with a uniform density. The spatial region is the unit circle.

[ p, t ] = cvt_circle_uniform ( n, sample_num, it_num, delaunay_display )
