IntegratedMesh3DTilesLayer

AMD: require(["esri/layers/IntegratedMesh3DTilesLayer"], (IntegratedMesh3DTilesLayer) => { /* code goes here */ });
ESM: import IntegratedMesh3DTilesLayer from "@arcgis/core/layers/IntegratedMesh3DTilesLayer.js";
Class: esri/layers/IntegratedMesh3DTilesLayer
Inheritance: IntegratedMesh3DTilesLayer Layer Accessor
Since: ArcGIS Maps SDK for JavaScript 4.29

The IntegratedMesh3DTilesLayer is designed for visualizing accurate representations of built and natural environments in a SceneView.

Integrated mesh data is typically captured by an automated process for constructing 3D objects from large sets of overlapping imagery. The result integrates the original input image information as a realistic textured mesh and can include elevation information and 3D objects, such as buildings and trees. Integrated mesh layers are generally created for citywide 3D mapping; they are often captured by drone and cannot be restyled.

The IntegratedMesh3DTilesLayer loads integrated mesh data based on a hierarchical data structure defined by the 3D Tiles specification. 3D Tiles are an OGC standard used to visualize large amounts of 3D content, similar to Indexed Scene Layer (I3S) scene layers. Currently, only JPEG and PNG textures are supported for 3D Tiles data loaded using the JavaScript Maps SDK.

The 3D Tiles Service is identified by the URL of the ArcGIS Server REST resource, specifically the 3D Tiles root tileset json file:

IntegratedMesh3DTilesLayer = new IntegratedMesh3DTilesLayer({
  url: "https://tiles.arcgis.com/tiles/0z60TleH1Y2qkUzY/arcgis/rest/services/Stuttgart_WGS84/3DTilesServer/tileset.json"
});

Property Details

apiKey

Property
apiKey String |null |undefined

An authorization string used to access a resource or service. API keys are generated and managed in the portal. An API key is tied explicitly to an ArcGIS account; it is also used to monitor service usage. Setting a fine-grained API key on a specific class overrides the global API key.

Example
// set the api key to access a protected service
const layer = new FeatureLayer({
  url: serviceUrl,
  apiKey: "YOUR_API_KEY"
});

customParameters

Property
customParameters Object |null |undefined

A list of custom parameters appended to the URL of all resources fetched by the layer. It's an object with key-value pairs where value is a string. The layer's refresh() method needs to be called if the customParameters are updated at runtime.

Example
// send a custom parameter to your special service
let layer = new MapImageLayer({
  url: serviceUrl,
  customParameters: {
    "key": "my-special-key"
  }
});

declaredClass

Inherited
Property
declaredClass Stringreadonly
Inherited from Accessor

The name of the class. The declared class name is formatted as esri.folder.className.

elevationInfo

Property
elevationInfo Object

Specifies how the mesh is placed on the vertical axis (z). This property only affects IntegratedMesh3DTilesLayers when using the absolute-height mode. Integrated mesh 3D Tiles layers always render in front of the ground surface, so setting negative offset values will not render them below the ground.

Properties
mode String

Defines how the mesh is placed on the vertical axis (z). Currently only absolute-height is supported.

Mode Description
absolute-height The mesh is placed at an absolute elevation (z-value) above sea level. This z-value is determined by summing up the offset value and the mesh's z-value. It doesn't take the elevation of the terrain into account. This is the only supported elevation mode for an IntegratedMesh3DTilesLayer.

The value is always "absolute-height".

optional

An elevation offset, which is added to the vertical position of the mesh.

optional

The unit for offset values.

fullExtent

Inherited
Property
fullExtent Extent |null |undefinedautocast
Inherited from Layer

The full extent of the layer. By default, this is worldwide. This property may be used to set the extent of the view to match a layer's extent so that its features appear to fill the view. See the sample snippet below.

Example
// Once the layer loads, set the view's extent to the layer's fullextent
layer.when(function(){
  view.extent = layer.fullExtent;
});

id

Property
id String
Inherited from Layer

The unique ID assigned to the layer. If not set by the developer, it is automatically generated when the layer is loaded.

listMode

Inherited
Property
listMode String
Inherited from Layer

Indicates how the layer should display in the LayerList widget. The possible values are listed below.

Value Description
show The layer is visible in the table of contents.
hide The layer is hidden in the table of contents.
hide-children If the layer is a GroupLayer, BuildingSceneLayer, KMLLayer, MapImageLayer, TileLayer or WMSLayer, hide the children layers from the table of contents.

Possible Values:"show" |"hide" |"hide-children"

Default Value:"show"

Possible Values:"not-loaded" |"loading" |"failed" |"loaded"

Default Value:not-loaded

loadWarnings

Inherited
Property
loadWarnings Object[]readonly
Inherited from Layer

A list of warnings which occurred while loading.

maxScale

Property
maxScale Number

The maximum scale (most zoomed in) at which the layer is visible in the view. If the map 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. The maxScale value should always be smaller than the minScale value, and greater than or equal to the service specification.

Default Value:0
Examples
// The layer will not be visible when the view is zoomed in beyond a scale of 1:1,000
layer.maxScale = 1000;
// The layer's visibility is not restricted to a maximum scale.
layer.maxScale = 0;

minScale

Property
minScale Number

The minimum scale (most zoomed out) at which the layer is visible in the view. If the map 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. The minScale value should always be larger than the maxScale value, and lesser than or equal to the service specification.

Default Value:0
Examples
// The layer will not be visible when the view is zoomed out beyond a scale of 1:3,000,000
layer.minScale = 3000000;
// The layer's visibility is not restricted to a minimum scale.
layer.minScale = 0;

opacity

Inherited
Property
opacity Number
Inherited from Layer

The opacity of the layer. This value can range between 1 and 0, where 0 is 100 percent transparent and 1 is completely opaque.

Default Value:1

persistenceEnabled

Property
persistenceEnabled Boolean

Enable persistence of the layer in a WebMap or WebScene.

Default Value:true

portalItem

Property
portalItem PortalItem |null |undefined

The portal item from which the layer is loaded. If the portal item references a Feature Service or Scene Service, then you can specify a single layer to load with the layerId property.

Beginning with version 4.17, it is possible to load tables from feature service items hosted in ArcGIS Online and ArcGIS Enterprise. This only applies to feature layers, and will successfully load if FeatureLayer.isTable returns true.

Examples
// While this example uses FeatureLayer, this same pattern can be
// used for other layers that may be loaded from portalItem ids.
const layer = new FeatureLayer({
  portalItem: {  // autocasts as new PortalItem()
    id: "caa9bd9da1f4487cb4989824053bb847"
  }  // the first layer in the service is returned
});
// Set hostname when using an on-premise portal (default is ArcGIS Online)
// esriConfig.portalUrl = "http://myHostName.esri.com/arcgis";

// While this example uses FeatureLayer, this same pattern can be
// used for SceneLayers.
const layer = new FeatureLayer({
  portalItem: {  // autocasts as new PortalItem()
    id: "8d26f04f31f642b6828b7023b84c2188"
  },
  // loads the third item in the given feature service
  layerId: 2
});
// Initialize GeoJSONLayer by referencing a portalItem id pointing to geojson file.
const layer = new GeoJSONLayer({
  portalItem: new PortalItem({
    id: "81e769cd7031482797e1b0768f23c7e1",
    // optionally define the portal, of the item.
    // if not specified, the default portal defined is used.
    // see https://developers.arcgis.com/javascript/latest/api-reference/esri-config.html#portalUrl
    portal: new Portal({
      url: "https://jsapi.maps.arcgis.com/"
    })
  }
});
// This snippet loads a table hosted in ArcGIS Online.
const table = new FeatureLayer({
  portalItem: { // autocasts as esri/portal/PortalItem
    id: "123f4410054b43d7a0bacc1533ceb8dc"
  }
});

// Before adding the table to the map, it must first be loaded and confirm it is the right type.
table.load().then(function() {
  if (table.isTable) {
    map.tables.add(table);
  }
});

spatialReference

Property
spatialReference SpatialReferenceautocast

The spatial reference of the layer.

title

Property
title String |null |undefined

The title of the layer used to identify it in places such as the LayerList widget.

When loading a layer by service url, the title is derived from the service name. When the layer is loaded from a portal item, the title of the portal item will be used instead. Finally, if a layer is loaded as part of a webmap or a webscene, then the title of the layer as stored in the webmap/webscene will be used.

type

Property
type Stringreadonly

For IntegratedMesh3DTilesLayer the type is always "integrated-mesh-3dtiles".

url

Property
url String

The URL of the root json file.

visibilityTimeExtent

Inherited
Property
visibilityTimeExtent TimeExtent |null |undefinedautocast
Inherited from Layer
Since: ArcGIS Maps SDK for JavaScript 4.30 Layer since 4.0, visibilityTimeExtent added at 4.30.

Specifies a fixed time extent during which a layer should be visible. This property can be used to configure a layer that does not have time values stored in an attribute field to work with time. Once configured, the TimeSlider widget will display the layer within the set time extent. In the case that only one of the start or end date values are available, the layer remains visible indefinitely in the direction where there is no time value.

Aerial imagery can capture seasonal variations in vegetation, water bodies, and land use patterns. For example, in agricultural regions, aerial imageries taken during different growing seasons provide insights into crop health and productivity. Defining a fixed time extent on imageries from specific time periods provides temporal context and facilitates focused analysis based on specific time periods or events.

visible

Inherited
Property
visible Boolean
Inherited from Layer

Indicates if the layer is visible in the View. When false, the layer may still be added to a Map instance that is referenced in a view, but its features will not be visible in the view.

Default Value:true
Example
// The layer is no longer visible in the view
layer.visible = false;

load

Inherited
Method
load(signal){Promise}
Inherited from Layer

Loads the resources referenced by this class. This method automatically executes for a View and all of the resources it references in Map if the view is constructed with a map instance.

This method must be called by the developer when accessing a resource that will not be loaded in a View.

The load() method only triggers the loading of the resource the first time it is called. The subsequent calls return the same promise.

It's possible to provide a signal to stop being interested into a Loadable instance load status. When the signal is aborted, the instance does not stop its loading process, only cancelLoad can abort it.

Parameter
signal AbortSignal
optional

Signal object that can be used to abort the asynchronous task. The returned promise will be rejected with an Error named AbortError when an abort is signaled. See also AbortController for more information on how to construct a controller that can be used to deliver abort signals.

Returns
Type Description
Promise Resolves when the resources have loaded.

on

Inherited
Method
on(type, listener){Object}
Inherited from Layer

Registers an event handler on the instance. Call this method to hook an event with a listener.

Parameters

An event or an array of events to listen for.

listener Function

obj.removeHandles("other-handle-group");

when

Inherited
Method
when(callback, errback){Promise}
Inherited from Layer

when() may be leveraged once an instance of the class is created. This method takes two input parameters: a callback function and an errback function. The callback executes when the instance of the class loads. The errback executes if the instance of the class fails to load.

Parameters
callback Function
optional

The function to call when the promise resolves.

errback Function
optional

The function to execute when the promise fails.

Returns
