/**
 * The Area Measurement 3D component can be added to an [arcgis-scene](https://developers.arcgis.com/javascript/latest/references/map-components/components/arcgis-scene/)
 * component to calculate and display area and perimeter of polygons.
 *
 * [![measurement-area-3d](https://developers.arcgis.com/javascript/latest/assets/references/core/widgets/3D_AreaMeasurement_widget.avif)](https://developers.arcgis.com/javascript/latest/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://developers.arcgis.com/javascript/latest/assets/references/core/widgets/area-measurement-3d-types.avif)
 *
 * 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 [arcgis-map](https://developers.arcgis.com/javascript/latest/references/map-components/components/arcgis-map/)
 * component, use [arcgis-area-measurement-2d](https://developers.arcgis.com/javascript/latest/references/map-components/components/arcgis-area-measurement-2d/).
 * * Snapping is enabled by default. Holding the `CTRL` key disables it.
 * * Layer types currently supported for snapping are:
 * [FeatureLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/FeatureLayer/),
 * [GraphicsLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/GraphicsLayer/) (except Mesh geometries),
 * [GeoJSONLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/GeoJSONLayer/),
 * [WFSLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/WFSLayer/),
 * [CSVLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/CSVLayer/),
 * [3D Object SceneLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/SceneLayer/),
 * and [BuildingSceneLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/BuildingSceneLayer/).

   * The [AreaMeasurementAnalysis](https://developers.arcgis.com/javascript/latest/references/core/analysis/AreaMeasurementAnalysis/)
   * created or modified by the component.
   *
   * When connecting the Area Measurement 3D component to the [arcgis-scene](https://developers.arcgis.com/javascript/latest/references/map-components/components/arcgis-scene/)
   * component, it automatically creates an empty analysis and adds it to the Scene's
   * [arcgis-scene.analyses](https://developers.arcgis.com/javascript/latest/references/map-components/components/arcgis-scene/#analyses) collection.
   * You can then wait for the [AreaMeasurementAnalysisView3D](https://developers.arcgis.com/javascript/latest/references/core/views/3d/analysis/AreaMeasurementAnalysisView3D/)
   * to be created before accessing the analysis results.
   *
   * ```js
   * // Get the Scene component and the Area Measurement 3D component, and wait until both are ready.
   * const viewElement = document.querySelector("arcgis-scene");
   * await viewElement.viewOnReady();
   * const areaMeasurement3dElement = document.querySelector("arcgis-area-measurement-3d");
   * await areaMeasurement3dElement.componentOnReady();
   *
   * // Get the AreaMeasurementAnalysis created by the Area Measurement 3D component.
   * const analysis = areaMeasurement3dElement.analysis;
   *
   * // Get the AreaMeasurementAnalysisView3D and watch for results.
   * const analysisView = await viewElement.whenAnalysisView(analysis);
   * const handle = reactiveUtils.watch(
   *   () => analysisView?.result,
   *   () => {
   *     console.log("Analysis results:", analysisView.result);
   *   },
   * );
   * ```
   * Whenever the component is destroyed, the analysis is automatically removed from the collection.
   *
   * Alternatively, a programmatically created [AreaMeasurementAnalysis](https://developers.arcgis.com/javascript/latest/references/core/analysis/AreaMeasurementAnalysis/)
   * can be provided to the component.
   * Then, the application itself needs to add it to and later remove it from the analyses collection of the Scene component.
   *
   * ```js
   * // Create the AreaMeasurementAnalysis.
   * const areaMeasurementAnalysis = new AreaMeasurementAnalysis({
   *    geometry: new Polygon({
   *      spatialReference: { latestWkid: 3857, wkid: 102100 },
