All Implemented Interfaces:

FigDrawable, FigObject

public class FigBezierXSpline

extends FigXSpline

a simple subclass of the generic FigXSpline which forces the control point scalefactors to values [0,-1,-1,...-1,0] (open spline) or [-1,-1,...,-1] (closed spline). Given the X-spline algorithm, this means that the spline will pass through the control points.

Method Detail

createSfactors

public void createSfactors()

Description copied from class: FigXSpline

default method to create the interpolation control sfactors. We use 1.0 (approximated) everywhere except for the end points.

Overrides:

createSfactors in class FigXSpline

copy

public FigObject copy()

Description copied from class: FigXSpline

build a copy of this FigXSpline.

Specified by:

copy in interface FigObject

Overrides:

copy in class FigXSpline
