Struct SphereSurface 

pub struct SphereSurface { /* private fields */ }

A sphere, parameterized by (longitude, latitude).

Implementations

impl SphereSurface

pub const fn new(sphere: Sphere) -> Self

A whole sphere.

pub const fn sphere(&self) -> Sphere

The underlying sphere.

Trait Implementations

impl Clone for SphereSurface

fn clone(&self) -> SphereSurface

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SphereSurface

impl Debug for SphereSurface

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

Formats the value using the given formatter.

impl From<SphereSurface> for SurfaceGeometry

fn from(s: SphereSurface) -> Self

Converts to this type from the input type.

impl PartialEq for SphereSurface

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

impl StructuralPartialEq for SphereSurface

impl Surface for SphereSurface

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

The u and v parameter intervals.

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

The point at (u, v).

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

The two first derivatives at (u, v).

fn d2_at( &self, u: f64, v: f64, tol: Tolerances, ) -> OgeomResult<(Vector, Vector, Vector)>

The three second derivatives at (u, v): d2u, duv, d2v.

fn kind(&self) -> SurfaceKind

What kind of surface this is.

fn continuity(&self) -> Continuity

How smooth the surface is across its domain.

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

Whether the surface closes on itself along u.

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

Whether the surface closes on itself along v.

fn is_periodic_u(&self) -> bool

Whether u repeats past the domain.

fn is_periodic_v(&self) -> bool

Whether v repeats past the domain.

fn jet_at(&self, u: f64, v: f64, tol: Tolerances) -> OgeomResult<SurfaceJet>

The point and every derivative through second order, together.

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

The unit normal at (u, v), following du x dv.

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

The principal curvatures and directions at (u, v).

fn is_degenerate_at(&self, u: f64, v: f64, tol: Tolerances) -> OgeomResult<bool>

Whether the surface degenerates at (u, v).

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

Bring (u, v) into the domain, wrapping in whichever directions are periodic, or closed.

fn parameter_outside( &self, t: f64, a: f64, b: f64, periodic: bool, across: bool, tol: Tolerances, ) -> OgeomResult<f64>

A parameter outside its domain, or on a periodic direction: wrapped where the direction repeats or closes on itself, refused otherwise.
