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.
Examples:
WikiExamples/Segmentation/VoronoiDiagram2DGenerator.cxx.
