Struct bevy::prelude::CubicBSpline

pub struct CubicBSpline<P>
where
    P: VectorSpace,
{ /* 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

Tangents are automatically computed based on the position of control points.

Continuity

The curve is C2 continuous, meaning it has no holes or jumps, and the tangent vector changes smoothly along the entire curve length. 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();
