project

@JsMethod
public Cartesian3 project(Cartographic cartographic)

Projects Cartographic coordinates, in radians, to projection-specific map coordinates, in meters.

Parameters:

cartographic - The coordinates to project.

Returns:

The projected coordinates. If the result parameter is not undefined, the coordinates are copied there and that instance is returned. Otherwise, a new instance is created and returned.

project

@JsMethod
public Cartesian3 project(Cartographic cartographic,
                                    Cartesian3 result)

Projects Cartographic coordinates, in radians, to projection-specific map coordinates, in meters.

Parameters:

cartographic - The coordinates to project.

result - An instance into which to copy the result. If this parameter is undefined, a new instance is created and returned.

Returns:

The projected coordinates. If the result parameter is not undefined, the coordinates are copied there and that instance is returned. Otherwise, a new instance is created and returned.

unproject

@JsMethod
public Cartographic unproject(Cartesian3 cartesian)

Unprojects projection-specific map Cartesian3 coordinates, in meters, to Cartographic coordinates, in radians.

Parameters:

cartesian - The Cartesian position to unproject with height (z) in meters.

Returns:

The unprojected coordinates. If the result parameter is not undefined, the coordinates are copied there and that instance is returned. Otherwise, a new instance is created and returned.

unproject

@JsMethod
public Cartographic unproject(Cartesian3 cartesian,
                                        Cartographic result)

Unprojects projection-specific map Cartesian3 coordinates, in meters, to Cartographic coordinates, in radians.

Parameters:

cartesian - The Cartesian position to unproject with height (z) in meters.

result - An instance into which to copy the result. If this parameter is undefined, a new instance is created and returned.

Returns:

The unprojected coordinates. If the result parameter is not undefined, the coordinates are copied there and that instance is returned. Otherwise, a new instance is created and returned.
