Method Detail

getPolygonFromUnsortedPointCloud

public static JavaPolygon2D getPolygonFromUnsortedPointCloud(JavaPoint2D... javaPoint2Ds)

Sorts the given point cloud

Parameters:

javaPoint2Ds - the point cloud

Returns:

the java polygon with the point cloud sorted.

getIntersection

public static JavaPolygon2D getIntersection(JavaPolygon2D jp1,
                                            JavaPolygon2D jp2)

Method for getting the intersection polygon of two polygons

Parameters:

jp1 - polygon 1 (must be sorted!)

jp2 - polygon 2 (must be sorted!)

Returns:

The intersection area as new JavaPolygon. Which is empty if given polygons are not sorted, are empty or there is no intersection area.
