EllipsoidTangentPlane

new EllipsoidTangentPlane(ellipsoid, origin)

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.
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:

Members

ellipsoid :Ellipsoid

Gets the ellipsoid.

origin :Cartesian3

Gets the origin.
