Method Details

clone

public Object clone()

Creates a new object of the same class as this object.
It then initializes each of the new object's fields by assigning it the same value as the corresponding field in this object. No
constructor is called.

Overrides:

clone in class Object

init

public void init(double pe,
 double pn)

init

public void init(WorldPt p)

init

public void init(String str)

initialize this WorldPt with the String str. str is in the form e, n

Parameters:

str -

length

public double length()

normalize

public void normalize()

getNormal

public WorldPt getNormal()

distToPoint

public double distToPoint(WorldPt pt)

distToLineSegSigned

public double distToLineSegSigned(WorldPt pt0,
 WorldPt pt1)

distToLineSeg

public double distToLineSeg(WorldPt pt0,
 WorldPt pt1)

distToLineSeg

public double distToLineSeg(WorldLineSeg l)

ptNearLineSeg

public double ptNearLineSeg(WorldPt pt0,
 WorldPt pt1,
 WorldPt ptn)

ptNearLineSegSigned

public double ptNearLineSegSigned(WorldPt pt0,
 WorldPt pt1,
 WorldPt ptn)

ptNearLineSeg

public double ptNearLineSeg(WorldLineSeg l,
 WorldPt ptn)

ptNearLineSegSigned
