curveipo - 2D curve interpolation

Example

use curveipo::{Curve, prelude::*};

// Float curve.
let curve = Curve::new([
    // (x, y) curve point
    (1.0_f32, -20.0_f32),
    (2.0, 2.0),
    (10.0, 20.0),
    (20.0, -17.0),
]);

// Linear interpolation in float curve with float result.
let x = 3.0;
let y_interpolated = curve.lin_inter(x);
float_eq::assert_float_eq!(y_interpolated, 4.25, abs <= 0.001);

// Integer curve.
let curve = Curve::new([
    // (x, y) curve point
    (1_i16, -20_i16),
    (2, 2),
    (10, 20),
    (20, -17),
]);

// Linear interpolation in integer curve with rounded integer result.
let x = 3;
let y_interpolated = curve.lin_inter(x);
assert_eq!(y_interpolated, 4);
