/**
* 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.
*
* [](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.
*
* 
*
* 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 },
* rings: [
