Struct Bezier

source

pub struct Bezier { /* private fields */ }

Expand description

A unit cubic Bézier curve, used for timing functions in CSS transitions and animations.

Implementations§

source §

impl Bezier

source

pub fn new(x1: f32, y1: f32, x2: f32, y2: f32) -> Bezier

Create a unit cubic Bézier curve from the two middle control points.

X coordinate is time, Y coordinate is function advancement. The nominal range for both is 0 to 1.

The start and end points are always (0, 0) and (1, 1) so that a transition or animation starts at 0% and ends at 100%.

source

pub fn solve(&self, x: f64, epsilon: f64) -> f64

Solve the bezier curve for a given x and an epsilon, that should be between zero and one.
