Wolfram Demonstrations Project Fortune's algorithm for voronoi diagrams given a finite set of points (called sites) in a plane, a voronoi diagram divides the plane into regions around each site that are closer to that site than to any of the others. this demonstration shows fortune's algorithm for drawing voronoi diagrams [1]. This is an implementation of fortune 's sweep line algorithm in processing. fortune's algorithm is used to generate the voronoi diagram of a set of points in the 2d plane. Whenever three parabolas intersect at the same point, this is where their voronoi cell boundaries will intersect. i call this a "circle event" because if you draw a circle through all three points, the intersection happens at the center of the circle, and the sweep line will be at the rightmost edge of the circle. Although it takes some effort to fully grasp its details, once understood, it opens up a range of possibilities for solving geometric problems. feel free to explore the code and demo linked above to see the algorithm in action, and i hope this breakdown helps you with your own implementation.

Fortune's algorithm the running of fortune's algorithm is visualized below. press any key to advance the algorithm one step. on any particular step, one of two things will happen: either a site will be added to the beach line, or a vertex edge will be added to the voronoi diagram. I saw many fortune algorithm tutorials contain figures of both directions (i.e. sweeping from top to bottom, and sweeping from bottom and top). thus when they describe the algorithm with words "under" or "above" etc, it's very very confusing. Sites x y x offset y offset scale step animate. Voronoi diagrams are fascinating geometric object with numerous applications. however, the process for their generation may be slow and complex. fortunately, there are elegant solutions to efficiently construct these diagrams. here is my javascript implementation of the fortune’s algorithm.
