EllipsoidTangentPlane

EllipsoidTangentPlane

new

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:

Methods

Returns:
Ellipsoid Gets the ellipsoid.

Returns:
Cartesian3 Gets the origin.

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.

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.

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

Parameters:

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>

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

Parameters:
