CVT_3D_SAMPLING is a MATLAB program which allows the user to carry out steps of Lloyd's iteration for approximating a Centroidal Voronoi Tessellation (CVT) in the unit cube.
The determination of the Voronoi regions is carried out using sampling. This means that the convergence of the iteration is influenced by the accuracy of the estimates provided by sampling.
