Struct HyperbolaCurve 

pub struct HyperbolaCurve { /* private fields */ }

One branch of a hyperbola.

Implementations

impl HyperbolaCurve

pub fn new(hyperbola: Hyperbola, extent: f64) -> OgeomResult<Self>

A hyperbola branch over [-extent, extent] in its natural parameter.

Errors

OgeomError::Construction if extent is not finite and positive.

pub fn over(hyperbola: Hyperbola, start: f64, end: f64) -> OgeomResult<Self>

A hyperbola branch over an arbitrary [start, end] in its natural parameter.

Errors

OgeomError::Construction if the interval is not finite and increasing.

pub const fn hyperbola(&self) -> Hyperbola

The underlying hyperbola.

pub const fn is_reversed(&self) -> bool

Whether the curve runs backwards along its underlying hyperbola.

Part of the curve’s state and not derivable from its hyperbola, so anything that has to reproduce this curve exactly (the native format above all) needs to be able to read it.

Trait Implementations

impl Clone for HyperbolaCurve

fn clone(&self) -> HyperbolaCurve

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for HyperbolaCurve

impl Curve3d for HyperbolaCurve

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

The parameter interval over which the curve is defined.

fn point_at(&self, u: f64, tol: Tolerances) -> OgeomResult<Point>

The point at u.

fn d1_at(&self, u: f64, tol: Tolerances) -> OgeomResult<Vector>

The first derivative at u.

fn derivatives_at( &self, u: f64, n: usize, tol: Tolerances, ) -> OgeomResult<Vec<Vector>>

Derivatives up to order n, with result[0] the point itself.

fn kind(&self) -> CurveKind

What kind of curve this is.

fn continuity(&self) -> Continuity

How smooth the curve is across its domain.

fn is_closed(&self, _tol: Tolerances) -> bool

Whether the curve’s ends meet.

fn is_periodic(&self) -> bool

Whether the curve continues past its domain by repeating.

fn tangent_at(&self, u: f64, tol: Tolerances) -> OgeomResult<Direction>

The unit tangent at u.

fn curvature_at(&self, u: f64, tol: Tolerances) -> OgeomResult<f64>

The curvature at u.

fn start(&self, tol: Tolerances) -> OgeomResult<Point>

The start point.

fn end(&self, tol: Tolerances) -> OgeomResult<Point>

The end point.

fn normalize_parameter(&self, u: f64, tol: Tolerances) -> OgeomResult<f64>

Bring u into the domain, wrapping if the curve is periodic.

impl Debug for HyperbolaCurve

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<HyperbolaCurve> for Curve

fn from(c: HyperbolaCurve) -> Self

Converts to this type from the input type.

impl PartialEq for HyperbolaCurve

fn eq(&self, other: &HyperbolaCurve) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
