Constructor Summary

PointSet3D()

PointSet3D(java.util.Collection<? extends Point3D> points)
Points must be a collection of java.awt.Point.

PointSet3D(int n)
Creates a new point set and allocate memory for storing the points.

PointSet3D(Point3D[] points)
Instances of Point3D are directly added, other Point are converted to Point3D with the same location.

Method Summary

void	addPoint(Point3D point) Adds a new point to the set of point.
void	addPoints(java.util.Collection<Point3D> points)
void	addPoints(Point3D[] points) Add a series of points
Box3D	boundingBox()
void	clearPoints() Removes all points of the set.
Shape3D	clip(Box3D box)
boolean	contains(Point3D point)
double	distance(Point3D p) Gets the distance of the shape to the given point, or the distance of point to the frontier of the shape in the case of a plain shape.
java.util.Iterator<Point3D>	getPoints() Returns an iterator on the internal point collection.
boolean	isBounded() Returns true if the shape is bounded, that is if we can draw a finite rectangle enclosing the shape.
boolean	isEmpty()
java.util.Iterator<Point3D>	iterator()
int	pointNumber() Returns the number of points in the set.

Constructor Detail

PointSet3D

public PointSet3D()

PointSet3D

public PointSet3D(int n)

Creates a new point set and allocate memory for storing the points.

Parameters:

n - the number of points to store

PointSet3D

public PointSet3D(Point3D[] points)

Instances of Point3D are directly added, other Point are converted to Point3D with the same location.

PointSet3D

public PointSet3D(java.util.Collection<? extends Point3D> points)

Points must be a collection of java.awt.Point. Instances of Point3D are directly added, other Point are converted to Point3D with the same location.

Parameters:

points -

Method Detail

addPoint

public void addPoint(Point3D point)

Adds a new point to the set of point. If point is not an instance of Point3D, a Point3D with same location is added instead of point.

Parameters:

point -

addPoints

public void addPoints(Point3D[] points)

Add a series of points

Parameters:

points - an array of points

addPoints

public void addPoints(java.util.Collection<Point3D> points)

getPoints

public java.util.Iterator<Point3D> getPoints()

Returns an iterator on the internal point collection.

Returns:

the collection of points

clearPoints

public void clearPoints()

Removes all points of the set.

pointNumber

public int pointNumber()

Returns the number of points in the set.

Returns:

the number of points

clip

public Shape3D clip(Box3D box)

Specified by:

clip in interface Shape3D

boundingBox

public Box3D boundingBox()

Specified by:

boundingBox in interface Shape3D

distance

public double distance(Point3D p)

Description copied from interface: Shape3D

Gets the distance of the shape to the given point, or the distance of point to the frontier of the shape in the case of a plain shape.

Specified by:

distance in interface Shape3D

contains

public boolean contains(Point3D point)

Specified by:

contains in interface Shape3D

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Shape3D

isBounded

public boolean isBounded()

Description copied from interface: Shape3D

Returns true if the shape is bounded, that is if we can draw a finite rectangle enclosing the shape. For example, a straight line or a parabola are not bounded.

Specified by:

isBounded in interface Shape3D

transform

public Shape3D transform(AffineTransform3D trans)

Specified by:

transform in interface Shape3D

iterator

public java.util.Iterator<Point3D> iterator()

Specified by:

iterator in interface java.lang.Iterable<Point3D>
