Since a delaunay triangulation is the dual graph of a voronoi diagram, you can construct the diagram from the triangulation in linear time. In such constructions, voronoi and delaunay concepts are used to tessellate an object space with respect to a given set of generators and then the construction is repeated every time with a new generator set, which comprises members selected from the previous generator set plus features of the current tessellation.
