Arc
A layer to visualize an ArcGIS scene service. Scene layers display content from a scene service or a scene package.
The ArcGISSceneLayer is a layer type optimized for displaying large amounts of data in a SceneView. The ArcGISSceneLayer class displays data published as scene services, scene layer packages (.slpk), and scene layers in mobile scene packages (.mspk).
ArcGISSceneLayer supports:
3D Object (e.g. buildings)
Integrated mesh (e.g. buildings, trees, and elevation) (see IntegratedMeshLayer)
Point features (e.g. trees)
The scene layer complies with the Indexed 3D Scene layer (I3S)[https://github.com/esri/i3s-spec] format. The I3S format is an open 3D content delivery format used to disseminate 3D GIS data to mobile, web, and desktop clients.
Functional characteristics
3D object — 3D object scene layers contain objects explicitly modeled in three dimensions and are used to represent objects such as buildings. These features have attributes and can be identified. See the 3D Object Scene Layer[https://pro.arcgis.com/en/pro-app/latest/help/mapping/layer-properties/the-3d-objects-scene-layer-in-arcgis-pro.htm] for more information.
Integrated mesh — 3D mesh data is typically captured by an automated process for constructing 3D objects out of large sets of overlapping imagery. The result integrates the original input image information as a textured mesh including 3D objects, such as buildings and trees, and elevation information. Integrated mesh scene layers are often created for citywide 3D mapping. They can represent something as small as a single building or as large as a city or state. They are often assembled automatically from imagery collected by a drone; they cannot be restyled because there is no underlying feature data. See the Integrated Mesh Scene Layer[https://pro.arcgis.com/en/pro-app/latest/help/mapping/layer-properties/the-integrated-mesh-scene-layer-in-arcgis-pro.htm] for more information.
Point features — To ensure fast visualization, cached scene layers are used to display large amounts of 3D point data about individual features, such as all the trees in a city. Point scene layers have features that can be identified and that have attributes that may be cached or available from an associated feature layer. The display of point scene layers is automatically thinned to improve performance and visibility at smaller scales and longer distances. Automatic thinning means that not all features are displayed at small scales; as you zoom in, additional features are displayed. See the Point scene layer[https://pro.arcgis.com/en/pro-app/latest/help/mapping/layer-properties/the-point-scene-layer-in-arcgis-pro.htm] for more information.
Point scene layers are generated from point feature layers. Point scene layers can be generated by ArcGIS Pro and hosted as a scene service or scene layer package.
Note: When publishing a scene from ArcGIS Pro (sharing as a web scene) any point feature layers in the 3D Layers section of the contents pane will be published as a scene service. The scene service will be referenced within the web scene.
Performance characteristics For a scene layer, the rendering of 3D data is based on the current level of detail (LOD), which is determined by the distance from the camera. Each object in a 3D object service is represented differently at various LODs determined by the camera distance. As the camera distance changes in the scene, objects will be displayed appropriately for the current LOD. This results in good client performance and low memory usage, at the expense of frequently loading and unloading objects.

Constructors
Creates scene layer object with a portal item.
Creates a Scene layer object. If the specified URI is a portal item URL (see PortalItem.PortalItem(String) for the supported URL formats), the underlying PortalItem will be created and accessible through Layer.item.
Properties
True if labels should be displayed. Note that this property is only supported for SceneLayerDataType.Point layers.
A filter applied to a feature-based ArcGISSceneLayer to include or exclude features within the polygons.
Inherited properties
An API key is a unique key used to authorize access to specific services and resources in ArcGIS Online. It is also used to monitor access to those services.
Defines the properties that allow a layer to be floor-aware. When a layer is configured as floor-aware, it has a FloorAware.floorDefinition property that defines properties that allow a layer to be floor-aware. When it is null (default value) the specific layer does not support floor filtering.
The unique identifying string for the layer, for example specified in a map or scene. The id is used by other parts of this API to refer to a specific Layer, such as in a set of FeatureFenceParameters or a FacilityLayerDefinition. If not supplied, all layers will be assigned a unique id when created.
Functions
Clears all selected features.
Clones the ArcGISSceneLayer.
Returns a list of the currently selected features.
Reset the visibility of all features back to their original state.
Selects the given feature and adds it to the current list of selected features.
Selects the features in the list and adds them to the current list of selected features.
Sets the visibility of the given features.
Sets the visibility of the given feature.
Unselects the given feature and removes it from the current list of selected features.
Unselects the features in the given list and removes them from the current list of selected features.
Inherited functions
Cancels loading metadata for the Loadable object.
Fetches the list of legend info.
Returns the layer content's effective visibility at the specified scale. Returns the effective layer content visibility. This effective visibility takes care of the effective visibility of the parents at the specified scale. Will return false if an error occurs.
