Constructor Detail

SimplePlanarPolygon3D

public SimplePlanarPolygon3D(Collection<Point3D> vertices)

Construct planar polygon in 3D from vertices

Parameters:

vertices - polygons vertices, must form a planar polygon

Method Detail

getVertices

public List<Point3D> getVertices()

Get vertices Read only.

getPlane

public Plane3D getPlane()

Get plane of the polygon

All polygon vertices are guaranteed to lie within the plane, but the specific origin, vector1, vector2 and coordinate subsystem derived from those are chosen arbitrarily.

getPolygonIn2d

public SimplePolygon2D getPolygonIn2d()

Get 2D projection of the polygon Vertex coordinates are determined by the coordinate subsystem of the plane of the polygon. See getPlane().

getCentroid

public Point3D getCentroid()

Get centroid

getArea

public double getArea()

Get area of the polygon

project

public Point3D project(Point3D point)

Project point

Parameters:

point - point to project

Returns:

closest point within the shape

getDistance

public double getDistance(Point3D from)

Get distance to a point

toString

public String toString()

Overrides:
