Voronoi diagram algorithm python

Nov 05,  · Delaunay Triangulation and Voronoi Diagram using OpenCV (C++ / Python) November 5, By Satya Mallick 55 Comments. There are many algorithms to find the Delaunay triangulation of a set of points. The most obvious (but not the most efficient) one is to start with any triangulation, and check if the circumcircle of any triangle. This is a fairly widely-used 2D code for Voronoi diagrams and Delauney triangulations, written in C by Steve Fortune of Bell Laboratories. It is based on Fortune's sweepline algorithm for Voronoi diagrams, and is likely to be the right code to try first. The most effecient algorithm to construct a voronoi diagram is Fortune's algorithm. It runs in O(n log n). Here is a link to his reference implementation in C. Personally I really like the python implementation by Bill Simons and Carson Farmer, since I found it easier to extend.

An implementation of Fortune's algorithm in python - Yatoom/voronoi. 0), (0, ), (0, 5), ]) # Initialize the algorithm v = Voronoi(polygon) # Create the diagram. A Voronoi diagram is a diagram consisting of a number of sites. But having stable and compact algorithm in Python (Sidef) made it possible to develop. The Voronoi diagram of a set of seed points divides space into several regions. Each region contains all points closer to one seed point than to any other seed.

GitHub Gist: instantly share code, notes, and snippets. Indices of the Voronoi vertices forming each Voronoi region. -1 indicates vertex outside the Voronoi diagram. point_region: list of ints, shape (npoints) Index of the Voronoi region for each input point. If qhull option “Qc” was not specified, the list will contain -1 for points that are not associated with a Voronoi . The Voronoi diagram is just a diagram: not a data structure or algorithm. I don't think it's suited to finding the nearest point in a set. Constructing the diagram would not change the asymptotic complexity of your problem, although it would make your problem more complicated and less memory efficient.

But having stable and compact algorithm in Python (Sidef) made it possible to develop looking the same Voronoi diagram in "pure" JavaScript. A few custom helper functions simplified code, and they can be used for any other applications. The most effecient algorithm to construct a voronoi diagram is Fortune's algorithm.

  1. Excuse for that I interfere … here recently. But this theme is very close to me. Is ready to help.

  2. In my opinion you are not right. I can defend the position. Write to me in PM, we will communicate.
