Enum Carrier

pub enum Carrier {
    Plane(Frame3),
    Ruled(RuledCarrier),
    Sphere {
        frame: Frame3,
        radius: f64,
    },
    Torus(TorusCarrier),
    Spline(Box<BSplineSurface>),
}

The surface a traced curve lies on, as the curve needs it, in the same parameterisation as the matching axiolid_surface family.

Variants

Plane(Frame3)

O + u X + v Y.

Ruled(RuledCarrier)

A cylinder, elliptical cylinder or cone.

Sphere

O + r cos v (cos u X + sin u Y) + r sin v Z.

Fields

frame: Frame3

Centre and axes.

radius: f64

Radius.

Torus(TorusCarrier)

A torus.

Spline(Box<BSplineSurface>)

A B-spline surface.

Implementations

impl Carrier

pub fn jet(&self, u: f64, v: f64) -> SurfaceJet

The point at (u, v) with its partials.

pub fn parameters(&self, p: DVec3) -> (f64, f64)

Principal parameters of a point on the carrier: angles in (-pi, pi] (a sphere’s latitude in [-pi/2, pi/2]); a caller reading a curve that runs past them adds whole turns. A B-spline carrier has no closed-form inverse: NaN, and the caller inverts the surface itself.

pub fn periodic(&self) -> (bool, bool)

Whether each parameter is an angle, periodic with 2 pi.

pub fn is_finite(&self) -> bool

Whether every number is finite.

Trait Implementations

impl Clone for Carrier

fn clone(&self) -> Carrier

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Carrier

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

Formats the value using the given formatter.

impl PartialEq for Carrier

fn eq(&self, other: &Carrier) -> 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.
