pub struct CubicCardinalSpline<P>
where P: Point,
{ /* private fields */ }
Expand description

A spline interpolated continuously across the nearest four control points, with the position of the curve specified at every control point and the tangents computed automatically.

Note the Catmull-Rom spline is a special case of Cardinal spline where the tension is 0.5.

Interpolation

The curve passes through every control point.

Tangency

Automatically defined at each control point.

Continuity

C1 continuous.

Usage

let points = [
    vec2(-1.0, -20.0),
    vec2(3.0, 2.0),
    vec2(5.0, 3.0),
    vec2(9.0, 8.0),
];
let cardinal = CubicCardinalSpline::new(0.3, points).to_curve();
let positions: Vec<_> = cardinal.iter_positions(100).collect();
