Struct PeriodicCurve3

pub struct PeriodicCurve3<'a> { /* private fields */ }

Verified closed-seam extension of a spatial B-spline curve.

As with PeriodicCurve2, this is an explicit evaluator/editing view over the existing clamped representation, not an inferred periodic knot schema.

Implementations

impl<'a> PeriodicCurve3<'a>

pub fn try_new( curve: &'a BSplineCurve<DVec3>, tolerance: Tolerance, ) -> Result<PeriodicCurve3<'a>, GeomError>

Validate closed metadata and at least positional seam continuity.

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

Native active parameter domain retained by this view.

pub const fn seam_continuity(self) -> SeamContinuity

Highest endpoint continuity verified during construction.

pub fn wrap_parameter(self, parameter: f64) -> Result<f64, GeomError>

Wrap a finite parameter into the native active domain.

pub fn evaluate(self, parameter: f64) -> Result<DVec3, GeomError>

Evaluate the closed-seam extension at any finite parameter.

pub fn jet(self, parameter: f64) -> Result<CurveJet<DVec3, DVec3>, GeomError>

Evaluate point, first derivative, and second derivative after wrapping.

pub fn insert_knot( self, parameter: f64, ) -> Result<BSplineCurve<DVec3>, GeomError>

Insert a shape-preserving knot at a periodic-equivalent interior parameter.

pub fn split_at( self, parameter: f64, ) -> Result<(BSplineCurve<DVec3>, BSplineCurve<DVec3>), GeomError>

Split at a periodic-equivalent interior parameter into two open curves.
