cubic_spline

Interpolation methods for computation of cubic spline points within the range of a discrete set of known points.

Online documentation Demo

Example for flatten vec

use cubic_spline::{Spline, SplineOpts};

let opts: SplineOpts = Default::default();

let points = vec![10.0, 200.0, 256.0, 390.0, 512.0, 10.0, 778.0, 200.0];

let spline_points = Spline::from_flatten_points(&points, &opts);

assert_eq!(spline_points.len(), 102);

Example for tuples vec

use cubic_spline::{Spline, SplineOpts};

let opts: SplineOpts = Default::default();

let points = vec![(10.0, 200.0), (256.0, 390.0), (512.0, 10.0), (778.0, 200.0)];

let spline_points = Spline::from_tuples(&points, &opts);

let (last_x, last_y) = spline_points.last().unwrap();
assert_eq!(last_y, 200.0);

Example for js

import { getCurvePoints } from 'cubic-spline-rs'

const NUM_OF_SEGMENTS = 22

const points = [10.0, 200.0, 256.0, 390.0, 512.0, 10.0, 778.0, 200.0]

const curvePoints = getCurvePoints( points, {
  num_of_segments: NUM_OF_SEGMENTS, // *optional
  // tension: 0.5, // *optional
  // disallow_x_stepping_back: false, // *optional
} )

Options

use cubic_spline::{SplineOpts};
let opts = SplineOpts {
  tension: 0.6,
  ..Default.default()
}

Enjoy using!
