geodeticSurfaceNormal
fun geodeticSurfaceNormal(cartesian: Cartesian3, result: Cartesian3? = definedExternally): Cartesian3(source)
Computes the normal of the plane tangent to the surface of the ellipsoid at the provided position.
Return
The modified result parameter or a new Cartesian3 instance if none was provided, or undefined if a normal cannot be found.
Parameters
cartesian
The Cartesian position for which to to determine the surface normal.
result
The object onto which to store the result.
