  • Voronoi Diagrams: Applications from Archaology to Zoology

    Different applications of Voronoi diagrams require different variations. For example, motion planning algorithims for circular robots often use the Voronoi diagram of the obstacles. If there is a path from one location to another, then there must be a path that follows the edges of the Voronoi diagram, since those edges are by definition as far from the obstacles as possible. Voronoi Diagrams. The Voronoi diagram of a discrete set of points X decomposes the space around each point X(i) into a region of influence R{i}.This decomposition has the property that an arbitrary point P within the region R{i} is closer to point i than any other point. The region of influence is called a Voronoi region and the collection of all the Voronoi regions is the Voronoi diagram. Computes and displays the Voronoi diagram for up to twelve control points (24 on iPad), selected by the user

    Voronoi diagram - Wikipedia

    For a set of n points the (n − 1) th-order Voronoi diagram is called a farthest-point Voronoi diagram. For a given set of points S = { p 1 , p 2 , ..., p n } the farthest-point Voronoi diagram divides the plane into cells in which the same point of P is the farthest point. Algorithm for generation of Voronoi Diagrams. You may use whatever algorithm you like to generate your Voronoi Diagrams, as long as it is yours (no using somebody's Voronoi generating package) and runs in at worst O(n^2) time. The algorithm below is the simplest algorithm we could come up with, and it runs in Theta(n^2) (for the truly curious, this bound holds in part because it can be proven ...

    Voronoi, Dutch-language web site dealing with Voronoi diagrams. Voronoi Art. Scott Sona Snibbe uses a retro-reflective floor to display the Voronoi diagram of people walking on it, exploring notions of personal space and individual-group relations. Additional Voronoi-based art is included in his dynamic systems series. These are Voroni diagrams (sometimes called Voronoi Tesesellations, Dirichlet Tessellations, or Thiessen polygons). They are named after Georgy Feodosevich Voronoi, a Ukrainian mathematician, who died in 1908. (To celebrate the centenary of Voronoi, Ukraine released a two-hryvnia coin for him).

    What are Voronoi Diagrams? - Voronoi Diagrams

    Voronoi Diagrams are also used to maximize control areas. If the meta game is about maximizing the controlled area and you can move in four directions, a good heuristic can be try to simulate a move in each of these 4 directions, and calculate the resulting Voronoi Diagram. The move that gives the largest Voronoi Area is probably the best move. Voronoi diagram has been one of the most important no-tions in computational geometry[1, 6]. A number of vari-ations of a Voronoi diagram defined for a set of points has been presented for different applications and purposes. In this paper we propose a yet another Voronoi diagram using a visual angle of a line segment from a point and investigate
