Scene Layer (ArcGISSceneServiceLayer)

The SceneLayer is a layer type designed for on-demand streaming and displaying large amounts of data in a SceneView. SceneLayers support two geometry types: Point and 3D Objects (e.g. buildings). The SceneLayer displays data published to a Scene Service. Scene Services can hold large volumes of features in an open format that is suitable for web streaming. The SceneLayer loads these features progressively, starting from coarse representations and refines them to higher detail as necessary for close-up views.

Properties

Property	Details
customParameters	A sequence of custom parameters appended to the URL of all requests related to a layer.
disablePopup	disablePopups allows a client to ignore popups defined by the service item.
id	A unique identifying string for the layer.
itemId	Optional string containing the item ID of the service if it's registered on ArcGIS Online or your organization's portal.
layerDefinition	A layerDefinition object defining the attribute schema and drawing information for the layer. See layerDefinition properties table.
layerType	String indicating the layer type. Valid value of this property ArcGISSceneServiceLayer
listMode	To show or hide layers in the layer list Valid values: hide show
opacity	The degree of transparency applied to the layer on the client side, where 0 is full transparency and 1 is no transparency.
path	For offline data, a path to a scene layer package file. A URI format is used, starting with file: followed by a file system path with an extension of .slpk. A relative path must be from the file which defines the layer. For example file:../p20/northamerica.slpk.
popupInfo	A popupInfo object defining the content of pop-up windows when you click or query a feature.
screenSizePerspective	Apply perspective scaling to screen-size symbols.
showLabels	If the layer has a labelingInfo property then labels show on the scene only if the showLabels property it true.
showLegend	Boolean value indicating whether to display the layer in the legend. Default value is true.
timeAnimation	Indicates whether to enable time animation if the layer supports it.
title	A user-friendly string title for the layer that can be used in a table of contents.
url	The URL to the service.
visibility	Boolean property determining whether the layer is initially visible in the web scene
visibilityTimeExtent	Represents time extent that will control when a layer should be visible based on webscene's current time. Visibility time extent only affects the layer visibility and will not filter the data.

layerDefinition properties

Property	Details
definitionExpression	SQL-based definition expression string that narrows the data to be displayed in the layer.
drawingInfo.labelingInfo[]	An array of labelingInfo objects.
drawingInfo.renderer	The renderer object contains the drawing information for the operationalLayer.
drawingInfo.transparency	Number value ranging between 0 (no transparency) to 100 (completely transparent).
elevationInfo	Elevation info defines how features are aligned to ground or other layers.
excludeObjectIds[]	Excludes features with the given object ids from rendering.
featureReduction	An object that specifies how features are reduced or aggregated, with the goal of decluttering the view or presenting the user with an aggregate visualization.
floorInfo	Contains floor-awareness information for the layer.
maxScale	Represents the maximum scale (most zoomed in) at which the layer is visible in the view. If the web scene is zoomed in beyond this scale, the layer will not be visible. A value of 0 means the layer does not have a maximum scale. If set, the maxScale value should always be smaller than the minScale value, and greater than or equal to the service specification.
minScale	Represents the minimum scale (most zoomed out) at which the layer is visible in the view. If the web scene is zoomed out beyond this scale, the layer will not be visible. A value of 0 means the layer does not have a minimum scale. If set, the minScale value should always be larger than the maxScale value, and lesser than or equal to the service specification.
polygonFilter	Polygon filter for scene layer features.
rangeInfos[]	Indicates range information
