Method Detail

getVertices

public List<Vector2D> getVertices()

Get the vertices of the convex hull.

Specified by:

getVertices in interface ConvexHull<Vector2D>

Returns:

vertices of the convex hull

getPath

public LinePath getPath()

Get a path defining the convex hull. The path will contain

• zero segments if the hull consists of only a single point,
• one segment if the hull consists of two points,
• three or more segments defining a closed loop if the hull consists of more than two non-collinear points.

Returns:

polyline path defining the convex hull

getRegion

public ConvexArea getRegion()

Return the region representing the convex hull. This will return null in cases where the hull does not define a region with non-zero size, such as when only a single unique point exists or when all points are collinear.

Specified by:

getRegion in interface ConvexHull<Vector2D>

Returns:

the region representing by the convex hull or null if the convex hull does not define a region of non-zero size

toString

public String toString()

Overrides:

toString in class Object
