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 PolyCubicBezierCurve2D clip(Box2D box)

Returns a new PolyCubicBezierCurve2D.

Specified by:

clip in interface ContinuousCurve2D

Specified by:

clip in interface Curve2D

Specified by:

clip in interface Shape2D

Overrides:

clip in class PolyCurve2D<CubicBezierCurve2D>

Parameters:

box - the clipping box

Returns:

the clipped shape

transform

public PolyCubicBezierCurve2D transform(AffineTransform2D trans)

Description copied from class: CurveArray2D

Transforms each curve, and build a new CurveArray2D with the set of transformed curves.

Specified by:

transform in interface ContinuousCurve2D

Specified by:

transform in interface Curve2D

Specified by:

transform in interface Shape2D

Overrides:
