ConvexPolygon

public ConvexPolygon(Point2D... vertices)

input vertices must be in order.

パラメータ:

vertices - Point2Ds for this. They must be in order and they must not have redundant points in the same side.

メソッドの詳細

getVertex

public Point2D getVertex(int i)

パラメータ:

i - index for a vertex

戻り値:

i th vertex

getEdge

public io.github.kensuke1984.kibrary.math.geometry.LineSegment getEdge(int i)

パラメータ:

i - index for an edge

戻り値:

i th edge

getArea

public double getArea()

戻り値:

the area of this

contains

public boolean contains(Point2D point)

パラメータ:

point - to look for

戻り値:

if point is inside this (true if the point is on the vertices)

getEdgeCount

public int getEdgeCount()

戻り値:

the number of edges (vertices)
