In surface reconstruction from slice samples (typical in medical imaging, coordinate measurement machines, stereolithography, etc.) the available methods attack the geometrical and topological aspects or a combina-tionof these. Topological methods classify the events occurred in the 2-manifold between two consecutive slices. Geometrical methods synthesize the surface based on local proximity of contours in consecutive slices. Many of these methods work with modifications of Voronoi-Delaunay (VD) techniques, applied on
