EllipsoidTangentPlane

new EllipsoidTangentPlane

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 as at the center of the ellipsoid, an exception will be thrown.

Parameters:

Name	Type	Description
`ellipsoid`	Ellipsoid	The ellipsoid to use.
`origin`	Cartesian3	The point on the surface of the ellipsoid where the tangent plane touches.

Throws:

DeveloperError : origin is required.
DeveloperError : origin must not be at the center of the ellipsoid.

Methods

getEllipsoid

Returns:

Ellipsoid Gets the ellipsoid.

getOrigin

Returns:

Cartesian3 Gets the origin.

projectPointOntoPlane

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

Parameters:

Name	Type	Argument	Description
`cartesian`	Cartesian3		The point to project.
`result`	Cartesian2	<optional>	The object onto which to store the result.

Throws:

DeveloperError : cartesian is required.

Returns:

Cartesian2 The modified result parameter or a new Cartesian2 instance if none was provided.

projectPointsOntoEllipsoid

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

Parameters:

Name	Type	Argument	Description
`cartesians`	Array		The array of points to project.
`result`	Array	<optional>	The array of Cartesian3 instances onto which to store results.

Throws:

DeveloperError : cartesians is required.

Returns:

Array The modified result parameter or a new array of Cartesian3 instances if none was provided.

projectPointsOntoPlane

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

Parameters:

Name	Type	Argument	Description
`cartesians`	Array		The array of points to project.
`result`	Array	<optional>	The array of Cartesian2 instances onto which to store results.

Throws:

DeveloperError : cartesians is required.

Returns:

Array The modified result parameter or a new array of Cartesian2 instances if none was provided.

<static> fromPoints

Creates a new instance from the provided ellipsoid and the center point of the provided Cartesians.

Parameters:

Name	Type	Description
`ellipsoid`	Ellipsoid	The ellipsoid to use.
`cartesians`	Cartesian3	The list of positions surrounding the center point.

Throws:

DeveloperError : cartesians is required.
