Class Vertex3DSpaceSimple

java.lang.Object
  cz.cuni.utils.math.vertexSpace.vertex3Dspace.Vertex3DSpaceSimple

All Implemented Interfaces:

Vertex3DSpaceInterface

public class Vertex3DSpaceSimple
extends java.lang.Object
implements Vertex3DSpaceInterface

In graphics we're in fact are working with discreet space. In math.M you have constants EPSILON / etc. which defines precision we're counting with. Vertex hash codes are created with respect to this precision (as they won't have doubles in x, y, z but long ~ discreet space). Idea behind this class is, that we're filling HashMap with vertexes and when we want to add vertex to a place where already someone is, we returns reference to an existing vertex instead.

Constructor Summary

Vertex3DSpaceSimple(Vertex3DFactoryInterface vfi)

Method Summary

void	clear() Clears information about vertices, which have been created.
Vertex3D	get(double x, double y, double z) Should return existing or new vertex which has "equal" coordinates.
Vertex3D	get(Tuple3D t) Should return existing or new vertex which has "equal" coordinates.
static void	main(java.lang.String[] args) This method is meant for testing the functionality of VertexSpace class.
void	remove(Vertex3D v) Vertex must be removed from the space
void	set(Vertex3D v) You have to insert this vertex into space, possibly overwriting the existing one.
