Method Detail

windingNumber

public static final int windingNumber(Collection<Point2D> vertices,
                                      Point2D point)
Computes the winding number of the polygon. Algorithm adapted from http://www.geometryalgorithms.com/Archive/algorithm_0103/algorithm_0103.htm

Parameters:
vertices - the vertices of the polygon
point - the reference point
Returns:
the number of windings of the curve around the point

createBuffer

public static final Domain2D createBuffer(Polygon2D polygon,
                                          double d)

union

public static final Polygon2D union(Polygon2D polygon1,
                                    Polygon2D polygon2)
