Class CircularInterpolation

java.lang.Object
  toxi.math.CircularInterpolation

All Implemented Interfaces:

InterpolateStrategy

public class CircularInterpolation
extends java.lang.Object
implements InterpolateStrategy

Implementation of the circular interpolation function. i = a-(b-a) * (sqrt(1 - (1 - f) * (1 - f) ))

Constructor Summary

CircularInterpolation()

CircularInterpolation(boolean isFlipped)
The interpolation slope can be flipped to have its steepest ascent towards the end value, rather than at the beginning in the default configuration.

Method Summary

float	interpolate(float a, float b, float f) Implements an interpolation equation.
void	setFlipped(boolean isFlipped)

CircularInterpolation

public CircularInterpolation()

CircularInterpolation

public CircularInterpolation(boolean isFlipped)

The interpolation slope can be flipped to have its steepest ascent towards the end value, rather than at the beginning in the default configuration.

Parameters:

isFlipped - true, if slope is inverted
