Voronoi diagrams
A Voronoi diagram divides a plane into regions based on distance from a set of given points. These given points are called sites. Every point inside a region is closer to its own site than to any other site. Voronoi diagrams are useful whenever we want to decide which location is closest, such as assigning houses to schools, hospitals, weather stations, or waste collection centres.
Key terms you need to know are:
- A site is one of the original points used to build the diagram.
- A cell is the region containing all points closest to one site.
- An edge is a boundary between two cells. Every point on an edge is the same distance from the two neighbouring sites.
- A vertex is a point where three edges meet. A vertex is the same distance from three sites.
