Method Detail

create

public static final PolyCubicBezierCurve2D create(Point2D... points)

Creates a series a cubic bezier curves, by grouping 4 adjacent points. Two consecutive curves share one point, N curves will require 3*n+1 points.

create

public static final PolyCubicBezierCurve2D create(Point2D[] points,
                                                  Vector2D[] vectors)

Creates a series a cubic bezier curves, by grouping consecutive couples of points and vectors. A polycurve composed of N Bezier curves requires N+1 points and N+1 vectors.

clip

public CurveSet2D<? extends PolyCubicBezierCurve2D> clip(Box2D box)

Returns a new set of PolyCubicBezierCurve2D.

Specified by:

clip in interface ContinuousCurve2D
