Class Vertex

java.lang.Object

com.macrofocus.treemap.voronoi.smoothing.Vertex

public class Vertex
extends java.lang.Object

This class represents a corner (or vertex) of voronoi cells. A corner is defined as contact point of three different cell pixels or to different cell pixels and the domain bounds or a corner in the domain bounds.
