Implementations§
Source§impl CurveParametric
impl CurveParametric
Sourcepub fn new(control_points: Vec<[f64; 3]>) -> Self
pub fn new(control_points: Vec<[f64; 3]>) -> Self
Create a new parametric curve from control points.
Sourcepub fn bezier_de_casteljau(&self, t: f64) -> [f64; 3]
pub fn bezier_de_casteljau(&self, t: f64) -> [f64; 3]
Evaluate a Bézier curve at parameter t ∈ [0, 1] using de Casteljau algorithm.
Works for any degree (number of control points - 1).
Sourcepub fn bezier_bernstein(&self, t: f64) -> [f64; 3]
pub fn bezier_bernstein(&self, t: f64) -> [f64; 3]
Evaluate a cubic Bézier curve using the Bernstein polynomial formula.
Requires exactly 4 control points. Falls back to de Casteljau for other counts.
Sourcepub fn bspline_de_boor(&self, t: f64, degree: usize, knots: &[f64]) -> [f64; 3]
pub fn bspline_de_boor(&self, t: f64, degree: usize, knots: &[f64]) -> [f64; 3]
Evaluate a B-spline at parameter t using the de Boor algorithm.
knots must have length = control_points.len() + degree + 1.
Sourcepub fn nurbs(
&self,
t: f64,
degree: usize,
knots: &[f64],
weights: &[f64],
) -> [f64; 3]
pub fn nurbs( &self, t: f64, degree: usize, knots: &[f64], weights: &[f64], ) -> [f64; 3]
Evaluate a NURBS curve at parameter t.
weights must have the same length as control_points.
Sourcepub fn sample_bezier(&self, n: usize) -> Vec<[f64; 3]>
pub fn sample_bezier(&self, n: usize) -> Vec<[f64; 3]>
Sample the Bézier curve at n uniformly spaced parameter values.
Sourcepub fn bezier_arc_length(&self, samples: usize) -> f64
pub fn bezier_arc_length(&self, samples: usize) -> f64
Compute the approximate arc length of the Bézier curve by sampling.
