Modifier and Type Method and Description
`abstract float` `interpolate(float x)`
This function takes an input value between 0 and 1 and returns another value, also between 0 and 1.
`static Interpolator` ```newBezierInterpolator(float px1, float py1, float px2, float py2)```
Builds a bezier interpolator with two control points (px1, py1) and (px2, py2).

```public static Interpolator newBezierInterpolator(float px1,
float py1,
float px2,
float py2)```
Builds a bezier interpolator with two control points (px1, py1) and (px2, py2). The points should all be in range [0, 1].
Parameters:
`px1` - the x-coordinate of first control point, between [0, 1]
`py1` - the y-coordinate of first control point, between [0, 1]
`px2` - the x-coordinate of second control point, between [0, 1]
`py2` - the y-coordinate of second control point, between [0, 1]
Returns:
new bezier interpolator
• interpolate

`public abstract float interpolate(float x)`
This function takes an input value between 0 and 1 and returns another value, also between 0 and 1.
Parameters:
`x` - a value between 0 and 1
Returns:
a value between 0 and 1. Values outside of this boundary may be clamped to the interval [0,1] and cause undefined results.
