Class Vertex3DSpaceCube

java.lang.Object
  cz.cuni.utils.math.vertexSpace.vertex3Dspace.Vertex3DSpaceCube

public class Vertex3DSpaceCube
extends java.lang.Object

This represent one cube of the VertexSpace. It may contain more then one vertex and is responsible for raising the errors if three vertices which are too close are inserted. It goes like this: 1) first vertex creates an epsilon surrounding, other vertices in those surrounding is reported as the first one 2) note that distance of 2 points may be 1.5 epsilon and the third one may lie in both surroundings - that's the time when error is reported Also - those cubes will be stored in HashMap for quick search. So we will need a hash and equal function. equals() is considering precision, size, x, y, z, NOT STORED VERTICES! Use add(Tuple3D) to insert and obtain a Vertex.
