Method Detail

createParallel

public static final PolyOrientedCurve2D<SmoothOrientedCurve2D> createParallel(Polyline2D polyline,
                                                                              double d)
Creates a curve parallel to the given polyline, at a distance d. The resulting curve is continuous, but can self-intersect. It is composed of line segments, and circle arcs.

Parameters:
polyline - the source curve
d - the signed distance between the original curve and its parallel
Returns:
the curve parallel to the original curve at a distance d

createClosedParallel

public static final BoundaryPolyCurve2D<SmoothOrientedCurve2D> createClosedParallel(LinearRing2D polyline,
                                                                                    double d)
Creates a curve parallel to the given polyline, at a distance d. The resulting curve is continuous, but can self-intersect. It is composed of line segments, and circle arcs.

Parameters:
polyline - the source curve
d - the signed distance between the original curve and its parallel
Returns:
the curve parallel to the original curve at a distance d

intersect

public static final Collection<Point2D> intersect(Polyline2D poly1,
                                                  Polyline2D poly2)
Return all intersection points between the 2 polylines.

Parameters:
poly1 - a polyline
poly2 - a polyline
Returns:
the set of intersection points
