cubic_spline

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

Online documentation

Example for flatten vec

use cubic_spline::Spline;

static TENSION: f64 = 0.5;
static NUM_OF_SEGMENTS: u32 = 16;

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, TENSION, NUM_OF_SEGMENTS);

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

Example for tuples vec

use cubic_spline::Spline;

static TENSION: f64 = 0.5;
static NUM_OF_SEGMENTS: u32 = 35;

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, TENSION, NUM_OF_SEGMENTS);

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

Enjoy using!
