Class DecimatedInterpolation

java.lang.Object
  toxi.math.DecimatedInterpolation

All Implemented Interfaces:

InterpolateStrategy

public class DecimatedInterpolation
extends java.lang.Object
implements InterpolateStrategy

Delivers a number of decimated/stepped values for a given interval. E.g. by using 5 steps the interpolation factor is decimated to: 0, 20, 40, 60, 80 and 100%. By default LinearInterpolation is used, however any other InterpolateStrategy can be specified via the constructor.
