/**
 * The Area Measurement 3D component can be added to a [Scene](https://doc.geoscene.cn/javascript/4.33/references/map-components/geoscene-scene/)
 * component to calculate and display area and perimeter of polygons.
 *
 * [![measurement-area-3d](https://doc.geoscene.cn/javascript/4.33/assets/img/apiref/widgets/3D_AreaMeasurement_widget.png)](https://doc.geoscene.cn/javascript/4.33/sample-code/measurement-3d/)
 *
 * How the area and perimeter are computed depends on the scene's spatial reference and the length of the measured perimeter.
 *
 * In **geographic coordinate systems** (GCS) and in **Web Mercator**:
 * - If the measurement's perimeter is below 100 km, they are computed in a Euclidean manner,
 *   in an [ECEF](https://en.wikipedia.org/wiki/ECEF) coordinate system (or equivalent on other planets).
 * - If the perimeter is above 100 km, they are computed geodetically, and the visualization takes
 *   the curvature of the planet into consideration.
 *
 * In **projected coordinate systems** (PCS), apart from Web Mercator, the area and perimeter
 * are always calculated in a Euclidean manner (in their respective PCS).
 *
 * The area may be visualized and calculated in two ways:
 * 1. If all the vertices are mostly coplanar (lying on the same plane),
 *    the measurement polygon is formed on that plane, and area and perimeter are calculated from its geometry.
 * 2. If the vertices don't form a planar surface, the measurement polygon
 *    is projected to a horizontal plane, and area and perimeter are calculated from its geometry.
 *
 * ![area-measurement-3d-types](https://doc.geoscene.cn/javascript/4.33/assets/img/apiref/widgets/area-measurement-3d-types.png)
 *
 * When the component is active, a horizontal "laser" line is drawn which indicates the height at the current mouse position.
 * This line can help in analyzing the heights of objects relative to each other and the terrain.
 *
 * **Things to consider**
 *
 * * Area Measurement 3D is designed to work in the Scene component. For measurements in the [Map](https://doc.geoscene.cn/javascript/4.33/references/map-components/geoscene-map/)
 * component, use [Area Measurement 2D](https://doc.geoscene.cn/javascript/4.33/references/map-components/geoscene-area-measurement-2d/).
 * * Snapping is enabled by default. Holding the `CTRL` key disables it.
 * * Layer types currently supported for snapping are:
 * [FeatureLayer](https://doc.geoscene.cn/javascript/4.33/api-reference/geoscene-layers-FeatureLayer.html),
 * [GraphicsLayer](https://doc.geoscene.cn/javascript/4.33/api-reference/geoscene-layers-GraphicsLayer.html) (except Mesh geometries),
 * [GeoJSONLayer](https://doc.geoscene.cn/javascript/4.33/api-reference/geoscene-layers-GeoJSONLayer.html),
 * [WFSLayer](https://doc.geoscene.cn/javascript/4.33/api-reference/geoscene-layers-WFSLayer.html),
 * [CSVLayer](https://doc.geoscene.cn/javascript/4.33/api-reference/geoscene-layers-CSVLayer.html),
 * [3D Object SceneLayer](https://doc.geoscene.cn/javascript/4.33/api-reference/geoscene-layers-SceneLayer.html),
 * and [BuildingSceneLayer](https://doc.geoscene.cn/javascript/4.33/api-reference/geoscene-layers-BuildingSceneLayer.html).
