Detailed Description

template<typename TCoordType>
class itk::VoronoiDiagram2DGenerator< TCoordType >

Implement the Sweep Line Algorithm for the construction of the 2D Voronoi Diagram.

Detailed information on this method can be found in: "A sweepline algorithm for Voronoi diagrams." S. Fortune, Algorithmica 2, 153-174, 1987.

Input parameters are: (1) Size of the region. (2) Seed points coordinates. These coordinates can also be randomly set.

Template Parameters
TCoordTypeThe type associated with the coordination of the seeds and the resulting vertices.
