Struct Face

pub struct Face<Proj> { /* private fields */ }

Represents a face on a TriSphere.

This is always a geodesic triangle.

Implementations

impl<Proj: Eq + Clone + BaseTriProjector> Face<Proj>

pub fn center(&self) -> [f64; 3]

The approximate position of the center of this face.

There is no strict definition or guarantees for this function, other than that the center of a face will be somewhere inside it. This is typically the fastest way to get a representative position on the face.

Trait Implementations

impl<Proj: Clone> Clone for Face<Proj>

fn clone(&self) -> Face<Proj>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Proj: Debug> Debug for Face<Proj>

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

Formats the value using the given formatter.

impl<Proj: Eq + Clone + BaseTriProjector> Face for Face<Proj>

type Vertex = Vertex<Proj>

The type of Vertex on the sphere.

type HalfEdge = HalfEdge<Proj>

The type of HalfEdge on the sphere.

fn index(&self) -> usize

The index of this vertex within the Sphere::faces list.

fn area(&self) -> f64

The area of this face.

fn num_sides(&self) -> usize

The number of sides (vertices or edges) that this face has.

fn side(&self, index: usize) -> HalfEdge<Proj>

Gets the HalfEdge which has the given index and this face as its inside.

fn vertex(&self, index: usize) -> Self::Vertex

Gets a Vertex of this face given its index within Face::vertices.

fn vertices(&self) -> impl Iterator<Item = Self::Vertex>

Iterates over the Vertexs of this face in counter-clockwise order.

fn sides(&self) -> impl Iterator<Item = Self::HalfEdge>

Iterates over the HalfEdges which have this face as their inside.

impl<Proj: Hash> Hash for Face<Proj>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<Proj: PartialEq> PartialEq for Face<Proj>

fn eq(&self, other: &Face<Proj>) -> 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.
