Constructor Detail

ConvexHull2D

public ConvexHull2D(Vector2D[] vertices,
                    double tolerance)
             throws MathIllegalArgumentException

Simple constructor.

Parameters:

vertices - the vertices of the convex hull, must be ordered

tolerance - tolerance below which points are considered identical

Throws:

MathIllegalArgumentException - if the vertices do not form a convex hull

Method Detail

getVertices

public Vector2D[] getVertices()

Get the vertices of the convex hull.

Specified by:

getVertices in interface ConvexHull<Euclidean2D,Vector2D>

Returns:

vertices of the convex hull

getLineSegments

public Segment[] getLineSegments()

Get the line segments of the convex hull, ordered.

Returns:

the line segments of the convex hull

createRegion

public Region<Euclidean2D> createRegion()
                                 throws MathIllegalArgumentException

Returns a new region that is enclosed by the convex hull.

Specified by:

createRegion in interface ConvexHull<Euclidean2D,Vector2D>

Returns:

the region enclosed by the convex hull

Throws:

MathIllegalArgumentException - if the number of vertices is not enough to build a region in the respective space
