EllipsoidTangentPlane

open external class EllipsoidTangentPlane(var origin: Cartesian3, var ellipsoid: Ellipsoid = definedExternally)(source)

A plane tangent to the provided ellipsoid at the provided origin. If origin is not on the surface of the ellipsoid, it's surface projection will be used. If origin is at the center of the ellipsoid, an exception will be thrown.

Properties

ellipsoid

external var ellipsoid: Ellipsoid

The ellipsoid to use. Default value - Ellipsoid.default

origin

external var origin: Cartesian3

The point on the surface of the ellipsoid where the tangent plane touches.

plane

external val plane: Plane

Gets the plane which is tangent to the ellipsoid.

xAxis

external val xAxis: Cartesian3

Gets the local X-axis (east) of the tangent plane.

yAxis

external val yAxis: Cartesian3

Gets the local Y-axis (north) of the tangent plane.

zAxis

external val zAxis: Cartesian3

Gets the local Z-axis (up) of the tangent plane.

Functions

projectPointOntoEllipsoid

external fun projectPointOntoEllipsoid(cartesian: Cartesian2, result: Cartesian3? = definedExternally): Cartesian3

Computes the projection of the provided 2D position onto the 3D ellipsoid.

projectPointOntoPlane

external fun projectPointOntoPlane(cartesian: Cartesian3, result: Cartesian2? = definedExternally): Cartesian2

Computes the projection of the provided 3D position onto the 2D plane, radially outward from the EllipsoidTangentPlane.ellipsoid coordinate system origin.

projectPointsOntoEllipsoid

external fun projectPointsOntoEllipsoid(cartesians: ReadonlyArray<Cartesian2>, result: ReadonlyArray<Cartesian3>? = definedExternally): ReadonlyArray<Cartesian3>

Computes the projection of the provided 2D positions onto the 3D ellipsoid.

projectPointsOntoPlane

external fun projectPointsOntoPlane(cartesians: ReadonlyArray<Cartesian3>, result: ReadonlyArray<Cartesian2>? = definedExternally): ReadonlyArray<Cartesian2>

Computes the projection of the provided 3D positions onto the 2D plane (where possible), radially outward from the global origin. The resulting array may be shorter than the input array - if a single projection is impossible it will not be included.

projectPointsToNearestOnPlane

external fun projectPointsToNearestOnPlane(cartesians: ReadonlyArray<Cartesian3>, result: ReadonlyArray<Cartesian2>? = definedExternally): ReadonlyArray<Cartesian2>

Computes the projection of the provided 3D positions onto the 2D plane, along the plane normal.

projectPointToNearestOnPlane

external fun projectPointToNearestOnPlane(cartesian: Cartesian3, result: Cartesian2? = definedExternally): Cartesian2

Computes the projection of the provided 3D position onto the 2D plane, along the plane normal.
