      org.gephi.ranking.api.Interpolator.BezierInterpolator

Enclosing class:

Interpolator

public static class Interpolator.BezierInterpolator
extends Interpolator

Bezier curve interpolator.

Basically, a cubic Bezier curve is created with start point (0,0) and endpoint (1,1). The other two control points (px1, py1) and (px2, py2) are given by the user, where px1, py1, px1, and px2 are all in the range [0,1].
