Method Summary

float	getLength() getLength will return the length of this line
int	getNumVerticies() should return the number of vertices on this line
boolean	isIntersectionPtOnLine(javax.vecmath.Point3f checkMe) This function is ONLY for use with getIntersectionPoints because it assumes the points passed in lies on the great circle formed by the line in question.

Constructor Detail

SphereShortLineModel

public SphereShortLineModel(SpherePointModel fPoint,
                            SpherePointModel sPoint,
                            SphereModel theSphere)

SphereShortLineModel construcotr

Parameters:

fPoint - first point for the line

sPoint - second point for the line

theSphere - The sphere model for this short line

Method Detail

getLength

public float getLength()

Description copied from class: SphereLineModel

getLength will return the length of this line

Specified by:

getLength in class SphereLineModel

Returns:

the length of the line

isIntersectionPtOnLine

public boolean isIntersectionPtOnLine(javax.vecmath.Point3f checkMe)

Description copied from class: SphereLineModel

This function is ONLY for use with getIntersectionPoints because it assumes the points passed in lies on the great circle formed by the line in question. It SHOULD NOT be used to try and tell if a point is on a line!

Specified by:

isIntersectionPtOnLine in class SphereLineModel

Parameters:

checkMe - The point to check against this line

Returns:

True if it's on the line false if it's not

update

public void update(java.util.Observable ob,
                   java.lang.Object arg)

Specified by:

update in interface java.util.Observer

Overrides:

update in class SphereLineModel

getNumVerticies

public int getNumVerticies()

Description copied from class: SphereMultiPointBase

should return the number of vertices on this line

Specified by:

getNumVerticies in class SphereMultiPointBase
