Struct bevy::prelude::CubicBSpline

pub struct CubicBSpline<P>
where
    P: Point,
{ /* private fields */ }

A spline interpolated continuously across the nearest four control points. The curve does not pass through any of the control points.

Interpolation

The curve does not pass through control points.

Tangency

Automatically computed based on the position of control points.

Continuity

C2 continuous! The acceleration continuity of this spline makes it useful for camera paths.

Usage

let points = [
    vec2(-1.0, -20.0),
    vec2(3.0, 2.0),
    vec2(5.0, 3.0),
    vec2(9.0, 8.0),
];
let b_spline = CubicBSpline::new(points).to_curve();
let positions: Vec<_> = b_spline.iter_positions(100).collect();
