Cmn
class CubicBezierEasing : Easing
A cubic polynomial easing.
The CubicBezierEasing class implements third-order Bézier curves.
This is equivalent to the Android PathInterpolator when a single cubic Bézier curve is specified.
Note: CubicBezierEasing instances are stateless and can be used concurrently from multiple threads.
Rather than creating a new instance, consider using one of the common cubic Easings:

CubicBezierEasing
CubicBezierEasing(a: Float, b: Float, c: Float, d: Float)
| Parameters | |
|---|---|
a: Float |
The x coordinate of the first control point. The line through the point (0, 0) and the first control point is tangent to the easing at the point (0, 0). |
b: Float |
The y coordinate of the first control point. The line through the point (0, 0) and the first control point is tangent to the easing at the point (0, 0). |
c: Float |
The x coordinate of the second control point. The line through the point (1, 1) and the second control point is tangent to the easing at the point (1, 1). |
d: Float |
The y coordinate of the second control point. The line through the point (1, 1) and the second control point is tangent to the easing at the point (1, 1). |
Public functions
transform
open fun transform(fraction: Float): Float
Transforms the specified fraction in the range 0..1 by this cubic Bézier curve. To solve the curve, fraction is used as the x coordinate along the curve, and the corresponding y coordinate on the curve is returned. If no solution exists, this method throws an IllegalArgumentException.
| Throws | |
|---|---|
kotlin.IllegalArgumentException |
If the cubic Bézier curve cannot be solved |
