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 must not be at the center of the ellipsoid.
