Class Vertex

java.lang.Object
  org.latdraw.diagram.Vertex

All Implemented Interfaces:

java.lang.Cloneable

public class Vertex
extends java.lang.Object
implements java.lang.Cloneable

This holds the position of an element in 3 formats: 3d raw, 3d normalized, and a 2d projection. In the 3d normalized form the z coordinate lies in [0, 1] and the projection to the x-y plane lies in the circle of radius 1/2. Also various force imformation is stored here.
