Class Interpolation

java.lang.Object

com.badlogic.gdx.math.Interpolation

Direct Known Subclasses:

Interpolation.BounceOut, Interpolation.Elastic, Interpolation.Exp, Interpolation.Pow, Interpolation.Swing, Interpolation.SwingIn, Interpolation.SwingOut

public abstract class Interpolation
extends java.lang.Object

Takes a linear value in the range of 0-1 and outputs a (usually) non-linear, interpolated value.
