backend.spheremodel
Class SphereLineIntrModel

java.lang.Object
  backend.spheremodel.SphereIntrModel
      backend.spheremodel.SphereLineIntrModel

All Implemented Interfaces:

java.util.Observer

public class SphereLineIntrModel
extends SphereIntrModel
implements java.util.Observer

SphereLineIntersectionModel models the internal details of an intersection

Constructor Summary

SphereLineIntrModel(SphereLineModel line1, SphereLineModel line2, SphereWorldModel theWorld)
This is the main constructor for the SphereLineIntrModel and should be used for everything except when a sphere is being read in from a file where it is impossible to use this constructor

SphereLineIntrModel(SphereModel theModel, SphereLineModel line1, SphereLineModel line2, SpherePointModel p1, SpherePointModel p2)
This constructor is ONLY meant to be used when reading a sphere in from a file because it does not do certain steps the normal constructor does .

Method Summary

boolean	equals(java.lang.Object checkMe)
SphereLineModel	getLineOne() getLineOne will get the first line of the intersection
SphereLineModel	getLineTwo() getLineTwo will get the second line of intersection
void	update(java.util.Observable arg0, java.lang.Object arg1)

Constructor Detail

SphereLineIntrModel

public SphereLineIntrModel(SphereLineModel line1,
                           SphereLineModel line2,
                           SphereWorldModel theWorld)

This is the main constructor for the SphereLineIntrModel and should be used for everything except when a sphere is being read in from a file where it is impossible to use this constructor

Parameters:

line1 - the first line of the intersection

line2 - the second line of the intersection

theWorld - is the SphereWolrdModel that this will be placed in

SphereLineIntrModel

public SphereLineIntrModel(SphereModel theModel,
                           SphereLineModel line1,
                           SphereLineModel line2,
                           SpherePointModel p1,
                           SpherePointModel p2)

This constructor is ONLY meant to be used when reading a sphere in from a file because it does not do certain steps the normal constructor does . So please, do me, and yourself a favor and DON'T use this unless you know EXACTLY what you are doing. I promise you can break things by using this wrong :)

Parameters:

theModel - is the SphereModel that this should be concerned with

line1 - is the first line of the intersection

line2 - is the second line of the intersection

p1 - is the first intersection point of the two lines. It is assumed that this has been setup correctly

p2 - is the second intersection point, but can also be null if no such intersection exists

Method Detail

update
