require(["esri/layers/IntegratedMeshLayer"], function(IntegratedMeshLayer) { /* code goes here */ });
esri/layers/IntegratedMeshLayer
The IntegratedMeshLayer is designed for visualizing accurate representations in a SceneView of infrastructure and natural landscapes that are difficult to access.
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 textured mesh using a triangular interlaced structure. An integrated mesh can represent built and natural 3D features, such as building walls, trees, valleys, and cliffs, with realistic textures. Integrated mesh scene layers will always render in front of the ground surface. They are generally created for citywide 3D mapping and can be created using Drone2Map for ArcGIS, which can then be shared to ArcGIS for Desktop or web apps.
The Scene Service is identified by the URL of the ArcGIS Server REST resource:
IntegratedMeshLayer = new IntegratedMeshLayer({
url: "https://tiles.arcgis.com/tiles/FQD0rKU8X5sAQfh8/arcgis/rest/services/VRICON_Yosemite_Sample_Integrated_Mesh_scene_layer/SceneServer"
});
If the service is requested from a different domain, a CORS enabled server or a proxy is required.

Property Details
- copyrightString
The copyright text as defined by the scene service.
- Since: ArcGIS API for JavaScript 4.7
The name of the class. The declared class name is formatted as
esri.folder.className
.
- elevationInfoObjectSince: ArcGIS API for JavaScript 4.5
Specifies how the mesh is placed on the vertical axis (z). This property only affects IntegratedMeshLayers when using the
absolute-height
mode. Integrated mesh 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 height above sea level. This height 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 IntegratedMeshLayer.optionaloffset NumberDefault Value:0An elevation offset, which is added to the vertical position of the mesh.
optionalunit StringDefault Value:metersThe unit for
offset
values.Possible Values: feet | meters | kilometers | miles | us-feet | yards
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; });
The unique ID assigned to the layer. If not set by the developer, it is automatically generated when the layer is loaded.
- layerIdNumber
The layer ID, or layer index, of a Scene Service layer. This is particularly useful when loading a single SceneLayer with the portalItem property from a service containing multiple layers. You can specify this value in one of two scenarios:
- When loading the layer via the portalItem property.
- When pointing the layer url directly to the Scene Service.
If a layerId is not specified in either of the above scenarios, then the first layer in the service (
layerId = 0
) is selected.Examples:// loads the third layer in the given Portal Item var layer = new SceneLayer({ portalItem: { id: "73df987984b24094b848d580eb83b0fb" }, layerId: 2 });
// If not specified, the first layer (layerId: 0) will be returned var layer = new SceneLayer({ portalItem: { id: "73df987984b24094b848d580eb83b0fb" } });
// Can also be used if URL points to service and not layer var layer = new SceneLayer({ url: "https://scenesampleserverdev.arcgis.com/arcgis/rest/services/Hosted/DevA_Trees/SceneServer", layerId: 0 // Notice that the url doesn't end with /2 });
// This code returns the same layer as the previous snippet var layer = new SceneLayer({ url: "https://scenesampleserverdev.arcgis.com/arcgis/rest/services/Hosted/DevA_Trees/SceneServer/0", // The layer id is specified in the URL });
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, hide the children layers from the table of contents. - Default Value:show
Indicates whether the layer's resources have loaded. When
true
, all the properties of the object can be accessed.- Default Value:false
The Error object returned if an error occurred while loading.
- Default Value:null
Represents the status of a load operation.
Value Description not-loaded The object's resources have not loaded. loading The object's resources are currently loading. loaded The object's resources have loaded without errors. failed The object's resources failed to load. See loadError for more details. - Default Value:not-loaded
A list of warnings which occurred while loading.
- portalItemPortalItem
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.
Examples:// while this example uses FeatureLayer, this same pattern can be // used for other layers that may be loaded from portalItem ids var lyr = 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 var lyr = new FeatureLayer({ portalItem: { // autocasts as new PortalItem() id: "8d26f04f31f642b6828b7023b84c2188" }, // loads the third item in the given feature service layerId: 2 });
- spatialReferenceSpatialReferenceautocast
The spatial reference of the layer.
- titleString
The title of the layer used to identify it in places such as the Legend and LayerList widgets.
When loading a layer by service url, the title is derived from the service name. If the service has several layers, then the title of each layer will be the concatenation of the service name and the layer 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.
- DeprecatedtokenStringreadonly
- since version 4.8. Will be removed at version 4.10.
Token generated by the token service using the specified userId and password. The recommended approach to pass a token on a layer is to use IdentityManager.registerToken().
- typeStringreadonly
For IntegratedMeshLayer the type is
integrated-mesh
.
- urlString
The URL of the REST endpoint of the layer or scene service. The URL may either point to a resource on ArcGIS Enterprise or ArcGIS Online.
The layer may be specified using the layerId property when the url points directly to a service and not a specific layer. If layerId is not specified, then it will default to the first layer in the service.
Examples:// Layer from Scene Service on ArcGIS Server var sceneLayer = new SceneLayer({ url: "http://scene.arcgis.com/arcgis/rest/services/Hosted/Building_Hamburg/SceneServer/layers/0" });
// Can also be used if URL points to service and not layer var layer = new SceneLayer({ // Notice that the url doesn't end with /0 url: "https://scenesampleserverdev.arcgis.com/arcgis/rest/services/Hosted/DevA_Trees/SceneServer", layerId: 0 });
- versionObjectreadonly
The version of the scene service specification used for this service.
- Properties:
- major Number
The major version of the scene layer.
minor NumberThe minor version of the scene layer.
versionString StringThe complete version string of the scene layer.
- See also:
Example:// Prints the version to the console - e.g. 1.4, 1.5, etc. console.log(layer.version.versionString);
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;
