Stereographic

engine/Source/Core/Stereographic.js 19
Represents a point in stereographic coordinates, which can be obtained by projecting a cartesian coordinate from one pole onto a tangent plane at the other pole. The stereographic projection faithfully represents the relative directions of all great circles passing through its center point. To faithfully represents angles everywhere, this is a conformal projection, which means points are projected onto an arbrary sphere.

Members

static constant Cesium.Stereographic.HALF_UNIT_SPHERE : Stereographic
engine/Source/Core/Stereographic.js 229

An Ellipsoid instance initialized to radii of (0.5, 0.5, 0.5).

conformalLatitude : number
engine/Source/Core/Stereographic.js 70

Computes the conformal latitude, or the ellipsoidal latitude projected onto an arbitrary sphere.

ellipsoid : Ellipsoid
engine/Source/Core/Stereographic.js 37

Gets the ellipsoid.

longitude : number
engine/Source/Core/Stereographic.js 84

Computes the longitude

x : number
engine/Source/Core/Stereographic.js 48

Gets the x coordinate

y : number
engine/Source/Core/Stereographic.js 59

Gets the y coordinate

Methods

static Cesium.Stereographic.clone(stereographic, result) → Stereographic
engine/Source/Core/Stereographic.js 206

Duplicates a Stereographic instance.
Name Type Description
stereographic Stereographic The Stereographic to duplicate.
result Stereographic optional The object onto which to store the result.
Returns:
The modified result parameter or a new Stereographic instance if one was not provided. (Returns undefined if stereographic is undefined)

static Cesium.Stereographic.fromCartesian(cartesian, result) → Sterographic
engine/Source/Core/Stereographic.js 132

Computes the projection of the provided 3D position onto the 2D polar plane, radially outward from the provided origin.
Name Type Description
cartesian Cartesian3 The point to project.
result Stereographic optional The object onto which to store the result.
Returns:
The modified result parameter or a new Sterographic instance if none was provided.

static Cesium.Stereographic.fromCartesianArray(cartesians, result) → Array.<Sterographic>
engine/Source/Core/Stereographic.js 182

Computes the projection of the provided 3D positions onto the 2D polar plane, radially outward from the provided origin.
Name Type Description
cartesians Array.<Cartesian3> The points to project.
result Array.<Stereographic> optional The object onto which to store the result.
Returns:
The modified result parameter or a new Sterographic instance if none was provided.

getLatitude(ellipsoid) → number
engine/Source/Core/Stereographic.js 105

Computes the latitude based on an ellipsoid.
Name Type Default Description
ellipsoid Ellipsoid Ellipsoid.WGS84 optional The ellipsoid on which to compute the longitude.
Returns:
The latitude
