Struct Gnomonic

pub struct Gnomonic;

The gnomonic projection.

This is the simplest and fastest projection. Given a point on a face of a BaseTriSphere, it first maps the point to the planar triangle, and then projects that point to the unit sphere using a perspective projection through the origin.

This projection has significant area inflation near the centers of faces and has kinks (C₁ discontinuities) along the edges of faces.

Trait Implementations

impl BaseTriProjector for Gnomonic

type Triangle = Planar

The type of Projection used for a basetri::Face.

fn inside(&self, edge: HalfEdge) -> Planar

Constructs a Projection for the inside face of the given edge, oriented such that the U axis goes along the edge.

impl Clone for Gnomonic

fn clone(&self) -> Gnomonic

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Gnomonic

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

Formats the value using the given formatter.

impl Default for Gnomonic

fn default() -> Gnomonic

Returns the “default value” for a type.

impl Hash for Gnomonic

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 PartialEq for Gnomonic

fn eq(&self, other: &Gnomonic) -> 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 TriProjector for Gnomonic

fn triangle(&self, [p_0, p_1, p_2]: [[f64; 3]; 3]) -> Planar

Constructs a Projection for a specified spherical triangle.

impl Copy for Gnomonic

impl Eq for Gnomonic

impl StructuralPartialEq for Gnomonic
