Struct CurveMidpoints 

pub struct CurveMidpoints { /* private fields */ }

A curve’s midpoints in f64: its control points, weights and knots each at the middle of its enclosure. For searches whose answer is a free choice — which parameter to measure a gap at, where to sample — many times cheaper than evaluating the enclosure, and off it only by roundings.

Implementations

impl CurveMidpoints

pub fn of(curve: &NurbCurve3D) -> Self

pub fn domain(&self) -> (f64, f64)

pub fn point(&self, t: f64) -> P3

The point at t, clamped into the domain: de Boor’s algorithm.
