Voronoi diagram by Intersection of Half-Planes

The definition of a Voronoi diagram is the partitioning of the plane into regions, directed by a set of points, such that all the points in one region are closer to that region's defining point than to any other defining point.
This means that the edges of the Voronoi diagram are segments taken from the perpendicular bisectors of the lines between the points. The segments can be seen as intersections of lines which divide the plane in half, hence the name of this algorithm.

There is also a movie which shows the Voronoi diagram of six control points, interrupted through the algorithm by questions posed to the student.

In addition, there are movies showing the half-plane intersection algorithm for ten and sixteen control points.
