Implementations

impl<const K: usize, const N: usize> SplineCurve<K, N>

pub fn new(t: Vec<f64>, c: Vec<f64>) -> Self

pub fn try_new(t: Vec<f64>, c: Vec<f64>) -> Result<Self, Box<dyn Error>>

pub fn evaluate(&self, u: &[f64]) -> Result<Vec<f64>>

Calulates spline coordinates for a collection of parameter values

The coordinates are given as a one-dimensional array, starting with the N —with N the dimension of the cuve— coordinates of the firt point, followed by the coordinates of all the other points. For example, for a two-dimensional curve (N=2), the (x,y)-coordinates are given as [x0, y0, x1, y1, x2, …] and for a three-dimensional curve, with coordinates (x,y,z) you will get [x0, y0, z0, x1, y1, z1, x2, y2 …]. If you need to convert them into individual coordinate arrays, I suggest to use the transpose function.
