Since: ArcGIS Maps SDK for JavaScript 4.0

Overview

A SceneView displays a 3D view of a Map or WebScene instance. To render a map and its layers in 2D, see the documentation for MapView. For a general overview of views, see View.

Various scenes

For a map to be visible to the user in the DOM, a SceneView must have both a valid Map instance and a DOM element with a non-zero height and width in which to render. Note that there must be valid data in the map, such as operational layers or a basemap with base layers, before the view will begin rendering the map.

// Create a basic SceneView instance with a basemap and world elevation
const view = new SceneView({
  // An instance of Map or WebScene
  map: new Map({
    basemap: "hybrid"
  }),

  // The id of a DOM element (may also be an actual DOM element)
  container: "viewDiv"
});

Using the view

A SceneView may not be immediately ready for display after it has been constructed. For example, map data may need to be loaded first to determine the spatialReference of the view, or the DOM container may not yet have a non-zero size. Many of the view methods (such as hitTest or goTo) need the view to be ready before they can be used.

// create a SceneView instance (for 3D viewing)
const view = new SceneView({
  map: new Map({
    basemap: "topo-vector"
  }),
  container: "viewDiv"
});

view.when(function() {
  // SceneView is now ready for display and can be used. Here we will
  // use goTo to view a particular location at a given zoom level, camera
  // heading and tilt.
  view.goTo({
    center: [-112, 38],
    zoom: 13,
    heading: 30,
    tilt: 60
  })
})
.catch(function(err) {
  // A rejected view indicates a fatal error making it unable to display,
  // this usually means that WebGL is not available, or too old.
  console.error("SceneView rejected:", err);
});

For live examples of view.when(), see the 2D overview map in SceneView and Toggle elevation layer samples.

SceneView navigation

The view can be navigated programmatically via goTo() and the view properties or interactively with mouse, keyboard or touch inputs. SceneView navigation is enabled by defaults, and includes the mouse, keyboard and touch interactions as described in the table below. Touch interactions are working on any touch enabled monitor or laptop screen.

Action SceneView behavior
Drag Pan
Double-click Zoom in at the cursor
Scroll forward Zoom in at the cursor
Scroll backward Zoom out at the center of the view
Right-click+Drag 3D-rotate around the center of the view
Arrow Keys Nudge the view left, right, up, or down (only supported in global scene)
B + Left-click+Drag 3D-rotate around the camera's position
P Move the camera to look perpendicular to the data displayed in the view
N Adjust the SceneView to point north
W Tilt camera up
A Rotate camera counterclockwise
S Tilt camera down
D Rotate camera clockwise
J Move down, closer to the view (only supported in global scene)
U Move up, higher from the view (only supported in global scene)
Drag with one or multiple fingers Pan
Double-tap with one finger Zoom in at the finger position
Two finger pinch in/out Zoom out/in
Move two fingers in clockwise or counterclockwise direction Rotate
Drag two fingers up or down the screen Tilt the scene

To disable SceneView navigation, you must call the stopPropagation() method on the event objects of the pointer or gesture events that trigger the navigation.

See our samples on disabling view navigation for examples.

SceneView navigation with Gamepad and 3DConnexion devices

Gamepad and 3Dconnexion devices, like the SpaceMouse, can be used for navigation when view.navigation.gamepad.enabled is set to true(default). Please see GamepadInputDevice for supported devices.

To disable gamepad navigation, you can set view.navigation.gamepad.enabled to false.

Note:

  • Per W3C Working Draft 29 October 2020, gamepad functionality may not be available on some or all browsers if the web application is hosted on a non-secure context (e.g. http rather than https). Future versions of the ArcGIS Maps SDK for JavaScript may explicitly disable gamepad capabilities on non-secure contexts.

Programmatic navigation

Traditional 2D mapping properties, such as scale, zoom, center and extent do not always work well in 3D. For example, a map's scale is not clear when viewed in the context of a globe. The SceneView therefore supports these properties on a best effort basis, with certain limitations (see the documentation of individual properties for more information).

// Compatibility with 2D viewing properties, such as center and zoom, allows
// convenient transitioning from the familiar use of the 2D MapView to the
// use of the SceneView for 3D viewing.
let view = new SceneView({
  map: new Map({
    basemap: "satellite"
  }),

  container: "viewDiv",

  // Sets the center point of the view at a specified lon/lat
  center: [-112, 38],

  // Sets the zoom LOD to 13
  zoom: 13
});

The nature of 3D viewing includes oblique views, z-values, and rotation, all of which add complexity to defining what is visible in the view. In contrast to 2D MapView, which are primarily defined by an extent, or center and scale, the primary view specification of the SceneView is a Camera instance. The camera is defined by a 3D position, heading and tilt. See the documentation of Camera for more details.

Because some view properties overlap (e.g. center and camera), there is a set priority in which these properties are applied during construction of the view (until the view becomes ready). The following table describes which properties have priority during view construction (properties that are overridden will have no effect during construction).

Property Overrides
camera viewpoint, extent, center, scale, zoom
viewpoint extent, center, scale, zoom
extent center, scale, zoom
scale zoom

It can be difficult to define the camera for viewing data at a particular location. The goTo method provides a convenient way to set the view's camera based on data (geometries, graphics) you want to view and from any perspective using heading, tilt, scale or zoom. Additionally, goTo will provide a smooth transition to the new location of the view by default.

// go to a location specified in geographic coordinates,
// from a 45 degree angle.
view.goTo({
  center: [-112, 38],
  heading: 45
});

// go to view all the graphics in view.graphics, while northing the
// the camera and tilting it to 60 degrees
view.goTo({
  target: view.graphics,
  heading: 0,
  tilt: 60
});

// Set the view to show an extent at a -20 degree heading, disabling the
// animated transition
view.goTo({
  target: new Extent(694942, 5596444, 1284090, 6163926, SpatialReference.WebMercator),
  heading: -20
}, {
  animate: false
});

Viewing modes

global vs local

The SceneView supports two different viewing modes, global (left picture above) and local (right picture above), specified by the viewingMode property. Global scenes render the earth as a globe, while local scenes render the surface on a flat plane. Local mode allows for navigation and feature display in a localized or clipped area. In both viewing modes the users may navigate the camera below the ground surface by setting the Ground.navigationConstraint.type to none.

The viewing mode (if not explicitly set by the user) is determined based on the spatial reference of the view. If the spatial reference is either Web Mercator, WGS84, CGCS2000, Mars_2000_(Sphere), GCS_Mars_2000 or GCS_Moon_2000 then the viewingMode will default to global. For any other spatial reference the viewingMode will default to local.

Supported coordinate systems

The SceneView supports following coordinate systems in a global scene:

  • WGS84, WebMercator and CGCS2000
  • Support for Mars_2000_(Sphere), GCS_Mars_2000 and GCS_Moon_2000 is experimental (see Visualize data on Mars sample). Scenes with these coordinate systems have the following limitations:
    • No support for dynamic layers, vector tile layers and scene layers
    • Daylight is currently not displayed correctly
    • Unable to be saved to a portal item

In a local scene the following coordinate systems are supported:

Noncached layers can be added to scenes with any spatial reference since they will be reprojected to the scene spatial reference. Scene layers with GCS WGS84 can also be added in scenes with Web Mercator spatial reference.

See spatialReference to learn how the spatial reference of a SceneView is derived.

Using elevation data

The SceneView will use elevation layers from the Map.ground as sources for elevation when rendering the ground surface. Similar to the basemap, the ground can be initialized with a well-known name, which creates it with a known set of elevation layers.

let view = new SceneView({
  map: new Map({
    basemap: "satellite",

    // A ground preset containing a single elevation layer, sourced from
    // https://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer
    ground: "world-elevation"
  },

  container: "viewDiv"
});

Local elevation layers can be added to the ground.layers to merge multiple elevation sources into a single surface. See 3D Map With Elevation Services for an example.

Handling events

When users interact with the SceneView, their actions trigger events that you can listen and respond to. For example, you can listen when a user moves the mouse over the map and display the coordinates at the mouse location. This is called a pointer-move event. See the SceneView events section for a list of all the events.

It is important to note that some events are dependent on each other and the timing of the user interaction can influence the type of event that gets triggered. For example, a single click triggers a series of events: pointer-down when the user presses the mouse button, pointer-up when they release the mouse button. An immediate-click event gets triggered right after the pointer-up event. immediate-click should be used for responding to user interaction without delay. The click event is only triggered after making sure that the user doesn't click a second time (in which case it would trigger a double-click event).

Various events

In the case of a double-click, the same event chain is repeated after the first click. However, if the user clicks a second time within a close time range, then the click event is not emitted anymore, but the pointer-down, pointer-up and immediate-click events are triggered again. After two immediate-click events, a double-click event gets triggered along with an immediate-double-click event. The difference between the two is that an immediate-double-click cannot be prevented by the use of stopPropagation on the immediate-click event and can therefore be used to react to double-clicking independently of usage of the immediate-click event.

These events are also used internally for navigation, popups or different interactive tools like measurement or sketch. In some use cases, adding additional event listeners might interfere with the default event listeners. For example, adding an immediate-click event to open up a popup, will interfere with the default click event that also opens up a popup.

See the Event explorer sample, to visualize the different events that get triggered when you interact with the view.

Known Limitations

  • The number of features that can be rendered in a SceneView varies depending on the qualityProfile of the view and the complexity of each feature's geometry and symbol. Layers with a large number of features are dynamically loaded and displayed as you navigate the scene. For optimal performance, the number of displayed features is adjusted based on the complexity of the symbol and device capability. As a result, some features may not be visible in the view.

  • SceneView does not support rendering of Multipoint geometry.

alphaCompositingEnabled

Property
alphaCompositingEnabled Boolean
Since: ArcGIS Maps SDK for JavaScript 4.8 SceneView since 4.0, alphaCompositingEnabled added at 4.8.

Allows the view to be partially or fully transparent when composited with the webpage elements behind it.

This property can only be set once at construction time. When alpha compositing is enabled, web scenes are less performant. It is important to set this property to true only when you need to apply transparency on the view.

Default Value:false
Example
// create a view with a fully transparent background
let view = new SceneView({
 map: map,
 alphaCompositingEnabled: true,
 environment: {
   background: {
     type: "color",
     color: [0, 0, 0, 0]
   },
   starsEnabled: false,
   atmosphereEnabled: false
 }
})

Allows for adding analyses directly to the default analyses in the View.

Examples
// Adds an analysis to the View
view.analyses.add(lineOfSightAnalysis);
// Removes an analysis from the View
view.analyses.remove(lineOfSightAnalysis);

animation

    }
  }
);

basemapView

Inherited
Property
basemapView BasemapView
Inherited from View

Represents the view for a single basemap after it has been added to the map.

breakpoints

Property
breakpoints Object

A convenience property used for defining the breakpoints on the height and width of the view. The sizes specified here determine the values of the widthBreakpoint and heightBreakpoint properties depending on the view's size.

Setting up breakpoints can aid in responsive app design. It does this by watching width and height breakpoints. This is helpful as it removes the need for multiple @media calls. Instead of listening for the view's size and/or resizes property, you can set up a watch handler for either the widthBreakpoint or heightBreakpoint properties of the view.

Please refer to the styling guide for additional information on working with this.

Properties
xsmall Number
optional
Default Value:544

Sets the xsmall breakpoint in pixels used by widthBreakpoint and heightBreakpoint. If the view's height or width is smaller than this value, then the value of widthBreakpoint or heightBreakpoint will be xsmall.

small Number
optional
Default Value:768

Sets the small breakpoint in pixels used by widthBreakpoint and heightBreakpoint. If the view's height or width is between this value and the value of the xsmall property, then the value of widthBreakpoint or heightBreakpoint will be small.

medium Number
optional
Default Value:992

Sets the medium breakpoint in pixels used by widthBreakpoint and heightBreakpoint. If the view's height or width is between this value and the value of the small property, then the value of widthBreakpoint or heightBreakpoint will be medium.

large Number
optional
Default Value:1200

Sets the large breakpoint in pixels used by widthBreakpoint and heightBreakpoint. If the view's height or width is between this value and the value of the medium property, then the value of widthBreakpoint or heightBreakpoint will be large.

xlarge Number
optional

Sets the xlarge breakpoint in pixels used by widthBreakpoint and heightBreakpoint. If the view's height or width is greater than the value of the large property, then the value of widthBreakpoint or heightBreakpoint will be xlarge.

Example
// Instead of watching the size or resizing properties
reactiveUtils.watch(() => view.size, () => {});
reactiveUtils.watch(() => view.resizing, () => {});

// Set up a watch handle for breakpoint

  () => view.widthBreakpoint,
  (breakpoint) => {
    switch (breakpoint) {
      case "xsmall":
      // do something

      case "xlarge":
      // do something else
        break;
      default:
    }
  }
);

camera

Property
camera Cameraautocast

The observation point from which the visible portion (or perspective) of the SceneView is determined. Contains properties including the elevation, tilt, and heading (in degrees) of the current view. Setting the camera immediately changes the current view. For animating the view, see goTo().

When set in the constructor, this property overrides the viewpoint, extent, center, scale, and zoom properties.

The camera property contains an internal reference which may be modified in the future. To persist or modify the camera, create a clone using camera.clone().

Z-values defined in a geographic or metric coordinate system are expressed in meters. However, in local scenes that use a projected coordinate system, vertical units are assumed to be the same as the horizontal units specified by the service.

See also
Examples
// Initializes the view at the given (x, y, z) position with a heading of 95 degrees.
// The position of the camera is a Point which will autocast in the sample
// below. Note that the default Point spatial reference is WGS84 which
// will only work if the SceneView has a Web Mercator or WGS84 spatial
// reference. For other spatial references, create a new position Point
// with an explicit spatial reference.
const view = new SceneView({
  camera: {
    position: [
       -122, // lon
         38, // lat
      50000  // elevation in meters
    ],

    heading: 95
  }
});
// Initializes the view at the given position with a tilt of 65 degrees
const view = new SceneView({
  camera: {
    position: {
      x: -100, // lon
      y: 45,   // lat
      z: 10654 // elevation in meters
    },

    tilt: 65
  }
});
// Clone the camera to modify its properties
const camera = view.camera.clone();

// Set new values for heading and tilt
camera.heading = 180;
camera.tilt = 45;

// Set the new properties on the view's camera
view.camera = camera;
// Set the view's camera to a new position, heading and tilt with the goTo() method
view.goTo({
  target: [-122, 38, 50000],
  heading: 180,
  tilt: 45
});

center

Property
center Pointautocast
Autocasts from Number[]|Object

Represents the view's center point; when setting the center you may pass a Point instance or an array of numbers representing at longitude/latitude pair ([-100.4593, 36.9014]). Setting the center immediately changes the current view. For animating the view, see goTo().

If set in the constructor, this property will be ignored if the viewpoint, camera, or extent properties are also set in the constructor.

The center property contains an internal reference which may be modified in the future. To persist or modify the center, create a clone using center.clone().

Z-values defined in a geographic or metric coordinate system are expressed in meters. However, in local scenes that use a projected coordinate system, vertical units are assumed to be the same as the horizontal units specified by the service.

See also
Examples
// Sets the initial center point of the view to long/lat coordinates
let view = new SceneView({
  center: [-112, 38]
});
// Updates the view's center point to a pre-determined Point object
view.center = new Point({
  x: 12804.24,
  y: -1894032.09,
  z: 12000,

  spatialReference: 2027
});
// view.center needs to be set (not modified in place) to have an effect.
// To modify only the center.x, first clone the current center, modify
// the .x property and then set it on the view.
let center = view.center.clone();

// Offset the center 1km to the east
center.x += 1000;

view.center = center;

clippingArea

Property
clippingArea Extentautocast

Represents an optional clipping area used to define the visible extent of a local scene. The clipping area cannot have z-values.

If defined, only features that intersect the area will be displayed. The clipping area applies to all layers types, including the ground and the basemap. The clipping area will not increase the area beyond the union of the extents of all layers, including the ground and the basemap. To do so, add a GraphicsLayer with a custom fullExtent to the scene.

The clippingArea property only applies to local scenes.

scene-clipping-area

The clippingArea property contains an internal reference which may be modified in the future. To persist or modify the clippingArea, create a clone using clippingArea.clone().

Example
let extent = view.extent.clone();

// Expand the extent in place, reducing it to 50% of its original size and set it as the clippingArea
view.clippingArea = extent.expand(0.5);

    },
    starsEnabled: false,
    atmosphereEnabled: false
  }
});

Changing the weather in the scene:

let view = new SceneView({
  container: "viewDiv",

  map: new Map({
    basemap: "satellite",
    ground: "world-elevation"
  }),
  environment: {
    weather: {
      type: "cloudy"   // autocasts as new CloudyWeather()
    }
  }
});
Properties
background Background
optional

Specifies how the background of the scene (which lies behind sky, stars and atmosphere) should be displayed. By default this is simply a single, fully opaque, black color. Currently ColorBackground is the only type of background supported.

optional
Default Value:SunLighting

Indicates the type of lighting in the scene.

Known Value Example
SunLighting scene-sun-lighting
VirtualLighting scene-virtual-lighting
atmosphereEnabled Boolean
optional
Default Value:true

Indicates whether atmosphere visualization is enabled. Disabling the atmosphere will also disable weather.

atmosphere Accessor
Deprecated Since version 4.27. Atmosphere conditions are now automatically chosen.
optional

Atmosphere conditions of the scene.

Specification
quality String
optional
Default Value:low

Indicates the quality of the atmosphere visualization. The quality of the atmosphere may have a significant impact on performance. This setting does not have any effect in local scenes.

Known Value Example
low scene-atmosphere
high scene-atmosphere

Possible Values:"low"|"high"

optional
Default Value:SunnyWeather

Indicates the type of weather visualization in the scene. This setting does not have any effect in local scenes.

Known Value Example
SunnyWeather scene-atmosphere
CloudyWeather scene-atmosphere
RainyWeather scene-atmosphere
SnowyWeather scene-atmosphere
FoggyWeather scene-atmosphere
starsEnabled Boolean
optional
Default Value:true

Indicates whether stars visualization is enabled.

extent

Property
extent Extentautocast

The extent represents the visible portion of a map within the view as an instance of Extent. Setting the extent immediately changes the view without animation. To animate the view, see goTo().

Rather than using extent to change the visible portion of the map in a SceneView, you should use camera since it easily allows you to define the heading, elevation and tilt of the observation point from which the view's perspective is created.

When set in the constructor, this property overrides the center, scale, and zoom properties. This property will be ignored if the viewpoint or camera are also set in the constructor.

The extent property contains an internal reference which may be modified in the future. To persist or modify the extent, create a clone using extent.clone().

Z-values defined in a geographic or metric coordinate system are expressed in meters. However, in local scenes that use a projected coordinate system, vertical units are assumed to be the same as the horizontal units specified by the service.

Default Value:null

performanceInfo

Property
performanceInfo SceneViewPerformanceInforeadonly
Since: ArcGIS Maps SDK for JavaScript 4.15 SceneView since 4.0, performanceInfo added at 4.15.

This property contains performance information in a SceneView like global memory usage and additional details for layers about memory consumption and number of features.

This property is experimental and should be used for debugging purposes only. Its interface will change in future releases.

Property
popup Popup

A Popup object that displays general content or attributes from layers in the map.

By default, the popup property is an empty object that allows you to set the popup options. A Popup instance is automatically created and assigned to the view's popup when the user clicks on the view and popupEnabled is true, when the view.openPopup() method is called, or when some widgets need the popup, such as Search. If popup is null, the popup instance will not be created.

Examples
// Set the view's popup to a new Popup instance.
// The popup will show anytime a popup is called such as when selecting features or displaying a Search result.
view.popup = new Popup();
// Set the popup to a PopupOptions object with popup properties set such as the dock options.
// The popup will show anytime a popup is called.
view.popup = {
 dockEnabled: true,
 dockOptions: {
   position: "top-left",
   breakpoint: false
 }
};
// Set the popup to null. This disables the popup so it will never show up.
view.popup = null;

popupEnabled

Property
popupEnabled Boolean
Since: ArcGIS Maps SDK for JavaScript 4.27 SceneView since 4.0, popupEnabled added at 4.27.

Controls whether the popup opens when users click on the view.

When true, a Popup instance is created and assigned to view.popup the first time the user clicks on the view, unless popup is null. The popup then processes the click event.

When false, the click event is ignored and popup is not created for features but will open for other scenarios that use a popup, such as displaying Search results.

Default Value:true
See also
Example
// Disable the popup from automatically appearing and
// open the popup manually using a click event.
view.popupEnabled = false;
view.on("click", (event)=> {
  view.openPopup({
    // Set properties for the manually opened popup
    ...
  });
});

qualityProfile

Property
qualityProfile String

SceneView can draw scenes in three different quality modes: high, medium and low.

The low quality profile significantly increases performance on slower browsers and devices by reducing the memory limit to 200MB. The memory limit impacts the SceneLayer's levels of detail and the number of features that are displayed in a FeatureLayer. Furthermore, low quality profile impacts visual quality by reducing map resolution, influencing atmospheric effects and disabling anti-aliasing (edge smoothing).

The high and medium quality profiles differ in the maximum amount of memory which the view is allowed to use (750MB for medium quality and 1.5GB for high quality). A higher memory limit improves quality in complex web scenes with many layers, but can have a negative impact on drawing performance and stability.

Physically based rendering (PBR) materials are enabled on all 3D objects in a SceneView in "high" quality mode. However, if a GLTF model or a 3D Object SceneLayer has PBR settings defined on the material, then these will be rendered in all quality modes.

In "high" quality mode, on a HiDPI display, graphics are rendered at a higher resolution depending on the browser's devicePixelRatio property.

SceneView performance depends on the amount of data being displayed, the quality profile and the device type. SceneView can be used to inspect the memory consumption and the number of features that are displayed for a specific scene. The SceneView memory resources sample shows how this property can be used.

The default value is based on the detected browser:

  • low for mobile devices
  • medium for any other browser

Possible Values:"low"|"medium"|"high"

Example
let view = new SceneView({
  qualityProfile: "high"
});

ready

Inherited
Property
ready Booleanreadonly
Inherited from View

When true, this property indicates whether the view successfully satisfied all dependencies, signaling that the following conditions are met.

When a view becomes ready it will resolve itself and invoke the callback defined in when() where code can execute on a working view. Subsequent changes to a view's readiness would typically be handled by watching view.ready and providing logic for cases where the map or container change.

Default Value:false
See also

resizing

Inherited
Property
resizing Booleanreadonly
Inherited from View

Indicates if the view is being resized.

Default Value:false

resolution

Inherited
Property
resolution Numberreadonly
Inherited from View
Since: ArcGIS Maps SDK for JavaScript 4.9 View since 4.0, resolution added at 4.9.

Represents the current value of one pixel in the unit of the view's spatialReference. The value of resolution is calculated by dividing the view's extent width by its width.

scale

Property
scale Number

Represents an approximation of the map scale at the center of the view. Setting the scale immediately changes the current view. For animating the view, see goTo().

When set in the constructor, this property overrides the zoom property. This property will be ignored if the viewpoint, camera, or extent properties are also set in the constructor.

See also
Example
// Set the approximate map scale at the center the view to 1:24,000
view.scale = 24000;

size

Inherited
Property
size Number[]readonly
Inherited from View

An array containing the width and height of the view in pixels, e.g. [width, height].

spatialReference

Property
spatialReference SpatialReferenceautocast

The spatial reference of the view. This indicates the projected or geographic coordinate system used to locate geographic features in the map. In a SceneView the following coordinate systems are available.

The spatial reference can either be set explicitly or automatically derived from the following:

In case the spatial reference is determined from the map layers or the ground layers and they are in WGS84 or Web Mercator, the following rule also applies: the first layer that does not support server side reprojection (tiled layers) determines the spatial reference of the view and all the other layers are reprojected.

If no spatial reference can be derived, then the view does not resolve and the ready property is false.

Default Value:null

stationary

Inherited
Property
stationary Booleanreadonly
Inherited from View

Indication whether the view is animating, being navigated with or resizing.

suspended

Inherited
Property
suspended Booleanreadonly
Inherited from View

Indicates if the view is visible on the page. When true, the view is not visible and it stops rendering and updating data. Set to true when one of the following conditions are met:

  • if the view does not have a container,
  • if the view's height or width equal to 0,
  • if the view container's css style display is set to none (display:none).

When the view container's css style visibility is set to hidden, this property is set to false, and the view is hidden but it stills renders and updates data.

Default Value:true

theme

Inherited
Property
theme Theme
Inherited from View
Since: ArcGIS Maps SDK for JavaScript 4.28 View since 4.0, theme added at 4.28.

This property specifies the base colors used by some widgets and components to render graphics and labels. This only affects those components that would otherwise use the default orange pattern.

Example
// Update the theme to use purple graphics
// and slightly transparent green text
view.theme = new Theme({
  accentColor: "purple",
  textColor: [125, 255, 13, 0.9]
});

timeExtent

Inherited
Property
timeExtent TimeExtentautocast
Inherited from View
Since: ArcGIS Maps SDK for JavaScript 4.12 View since 4.0, timeExtent added at 4.12.

The view's time extent. Time-aware layers display their temporal data that falls within the view's time extent. Setting the view's time extent is similar to setting the spatial extent because once the time extent is set, the view updates automatically to conform to the change.

Default Value:null
Example
// Create a csv layer from an online spreadsheet.
let csvLayer = new CSVLayer({
  url: "http://test.com/daily-magazines-sold-in-new-york.csv",
  timeInfo: {
    startField: "SaleDate" // The csv field contains date information.
  }
});

// Create a mapview showing sales for the last week of March 2019 only.
const view = new MapView({
  map: map,
  container: "viewDiv",
  timeExtent: {
    start: new Date("2019, 2, 24"),
    end:   new Date("2019, 2, 31")
  }
});

type

Property
type Stringreadonly

The type of the view.

For SceneView the type is always "3d".

ui

Inherited
Property
ui DefaultUIautocast
Inherited from View

Exposes the default widgets available in the view and allows you to toggle them on and off. See DefaultUI for more details.

Examples
let toggle = new BasemapToggle({
  view: view,
  nextBasemap: "hybrid"
});
// Adds an instance of BasemapToggle widget to the
// top right of the view.
view.ui.add(toggle, "top-right");
// Moves the zoom and BasemapToggle widgets to the
// bottom left of the view.
view.ui.move([ "zoom", toggle ], "bottom-left");
// Removes all the widgets from the bottom left of the view
view.ui.empty("bottom-left");
// Removes the compass widget from the view
view.ui.remove("compass");
// Removes all default UI components, except Attribution.
// Passing an empty array will remove all components.
view.ui.components = [ "attribution" ];

updating

Inherited
Property
updating Booleanreadonly
Inherited from View

Indicates whether the view is being updated by additional data requests to the network, or by processing received data.

Default Value:false

viewingMode

Property
viewingMode String

The viewing mode (local or global). Global scenes render the earth as a sphere. Local scenes render the earth on a flat plane and allow for navigation and feature display in a localized or clipped area. Users may also navigate the camera of a local scene below the surface of a basemap.

Value Example Description
global scene-global Global scenes allow the entire globe to render in the view, showing the curvature of the earth.
local scene-local Local scenes render the earth on a flat surface. They can be constrained to only show a "local" area by setting the clippingArea property. Local scenes also allow for displaying and exploring data that would otherwise be hidden by the surface of the earth.

Depending on the viewing mode different supported coordinate systems are available.

Possible Values:"global"|"local"

Default Value:global
See also

viewpoint

Property
viewpoint Viewpointautocast

Represents the current view as a Viewpoint or point of observation on the view. In SceneViews, camera should be used in favor of viewpoint for watching or changing the point of view. Setting the viewpoint immediately changes the current view. For animating the view, see goTo().

When set in the constructor, this property overrides the extent, center, scale, and zoom properties. This property will be ignored if camera is also set in the constructor.

The viewpoint property contains an internal reference which may be modified in the future. To persist or modify the viewpoint, create a clone using viewpoint.clone().

See also

width

Inherited
Property
width Numberreadonly
Inherited from View

The width of the view in pixels read from the view container element.

The view container needs to have a width greater than 0 to be displayed.

Default Value:0

widthBreakpoint

Property
widthBreakpoint String

A convenience property indicating the general size of the view's width. This value is determined based on where the view's width falls in the ranges defined in the breakpoints property. See the table below for a list of possible values. Use the breakpoints property to override the default thresholds.

Please refer to the styling guide for additional information on working with this.

Possible Value Description Default thresholds (pixels)
xsmall The width of the view is smaller than the value set in the xsmall breakpoint. < 545
small The width of the view is between the values set in the xsmall and small breakpoints. 545 - 768
medium The width of the view is between the values set in the small and medium breakpoints. 769 - 992
large The width of the view is between the values set in the medium and large breakpoints. 993 - 1200
xlarge The width of the view is larger than the value set in the large breakpoint. > 1200

Possible Values:"xsmall"|"small"|"medium"|"large"|"xlarge"

Example
reactiveUtils.when(
  () => view.widthBreakpoint === "xsmall",
  () => {
    // clear the view's default UI components if
    // the app is used on a mobile device
    view.ui.components = [];
  }
);

zoom

Property
zoom Number

Represents the level of detail (LOD) at the center of the view. Setting the zoom immediately changes the current view. For animating the view, see goTo().

Setting this property in conjunction with center is a convenient way to set the initial extent of the view.

If set in the constructor, this property will be ignored if the viewpoint, camera, extent, or scale properties are also set in the constructor.

See also
Examples
view.zoom = 3;  // Sets the LOD to 3 (small map scale)
view.zoom = 18; // Sets the LOD to 18 (large map scale)
// Set the zoom level and center in the constructor
let view = new SceneView({
  zoom: 10,
  center: [-120, 34],
  map: map
});

Method Details

addHandles

Inherited
Method
addHandles(handleOrHandles, groupKey)
Inherited from Accessor
Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, addHandles added at 4.25.

Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.

// Manually manage handles
const handle = reactiveUtils.when(
  () => !view.updating,
  () => {
    wkidSelect.disabled = false;
  },
  { once: true }
);

this.addHandles(handle);

// Destroy the object
this.destroy();
Parameters
handleOrHandles WatchHandle|WatchHandle[]

Handles marked for removal once the object is destroyed.

groupKey *
optional

Key identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.

closePopup

Method
closePopup()
Since: ArcGIS Maps SDK for JavaScript 4.27 SceneView since 4.0, closePopup added at 4.27.

Closes the popup.

See also
Example
// Closes the popup if it's open
if(view.popup.visible){
 view.closePopup();
}

destroy

Inherited
Method
destroy()
Inherited from View
Since: ArcGIS Maps SDK for JavaScript 4.17 View since 4.0, destroy added at 4.17.

Destroys the view, and any associated resources, including its map, popup, and UI elements. These can no longer be used once the view has been destroyed. To prevent these components from being destroyed, remove them from the view before calling destroy().

// remove popup and legend from the view so that they are not destroyed
const popup = view.popup;
view.popup = null;
view.ui.remove(legend);

// unset map from the view so that it is not destroyed
const map = view.map;
view.map = null;

// destroy the view and any remaining associated resources
view.destroy();

emit

Inherited
Method
emit(type, event){Boolean}
Inherited from View
Since: ArcGIS Maps SDK for JavaScript 4.5 View since 4.0, emit added at 4.5.

Emits an event on the instance. This method should only be used when creating subclasses of this class.

Parameters
type String

The name of the event.

event Object
optional

The event payload.

Returns
Type Description
Boolean true if a listener was notified

focus

Inherited
Method
focus()
Inherited from View
Since: ArcGIS Maps SDK for JavaScript 4.5 View since 4.0, focus added at 4.5.

Sets the focus on the view.

goTo

Method
goTo(target, options){Promise}

Sets the view to a given target. The target parameter can be one of the following:

  • [longitude, latitude] pair of coordinates
  • Geometry (or array of Geometry[])
  • Graphic (or array of Graphic[])
  • Viewpoint
  • Camera
  • Object with a combination of target, center, scale, position, heading and tilt properties (with target being any of the types listed above). The center property is provided as a convenience to animate the SceneView.center and is the equivalent of specifying the target with the center Point. The target must be provided in the spatial reference of the view.

This function returns a promise which resolves as soon as the new view has been set to the target. If the transition is animated, then the ongoing animation can be obtained using SceneView.animation. If setting the view to the new target fails, the promise returned by the goTo() method rejects with an error. Use a catch statement, to handle the error:

view.goTo({
  center: [-126, 49]
})
.catch(function(error) {
  if (error.name != "AbortError") {
     console.error(error);
  }
});

If the given target is far away from the current camera position, then heading and tilt will be automatically set to their neutral values (facing north, looking top down). Tilt and heading can always be explicitly set to override this behavior.

Parameters
target GoToTarget3D

The target location/viewpoint to go to. When using an object for target, use the properties defined in GoToTarget3D.

options GoToOptions3D
optional

View transition options. See the specification defined in GoToOptions3D for more information.

Returns
Type Description
Promise A promise that resolves when the view's extent updates to the extent defined in target.
Examples
view.goTo({
  center: [-126, 49],
  heading: 180, // set the heading to point South
  tilt: view.camera.tilt, // maintain tilt value
});
// go to a location defined by a Camera object
let cam = new Camera({
  position: new Point({
    x: -100.23, // lon
    y: 65,      // lat
    z: 10000,   // elevation in meters
  }),

  heading: 180, // facing due south
  tilt: 45      // bird's eye view
});

view.goTo(cam);
// go to a point using center, zoom, tilt, and heading
view.goTo({
  center: [-126, 49],
  zoom: 13,
  tilt: 75,
  heading: 105
});
// goTo returns a Promise which resolves when the animation has finished.
// This promise may be chained to create a sequence of animations.

hitTest

Method
hitTest(screenPoint, options){Promise<HitTestResult>}

Returns hit test results from each layer that intersects the specified screen coordinates. The results are organized as an array of objects containing different result types.

The following layer types will return all features if a hit is made on intersecting features: GraphicsLayer, FeatureLayer, SceneLayer, BuildingSceneLayer, PointCloudLayer, CSVLayer, StreamLayer, GeoJSONLayer, OGCFeatureLayer, and SceneView.graphics.

The MediaLayer hit test result contains all media elements if the hit is made on intersecting elements. The RouteLayer hit test result contains all route elements if the hit is made on intersecting elements.

The VoxelLayer hit test result contains information about the intersecting voxel if a hit is made.

If no options are specified, graphics that are behind the ground surface will not be returned unless the ground surface is semi-transparent. Otherwise, using the map.ground in the include and exclude options determines whether the ground surface prevents hit testing graphics that are under it.

If the graphics have non-draped IconSymbol3DLayer symbology, then only the first graphic will be returned from the hitTest.

Release specific changes:

  • At version 4.24, HitTestResult returns an array of objects containing graphic, media element, and route.
  • Starting with version 4.11, if a label intersects the specified screen coordinates then the result of the hitTest will contain the graphic associated with that label.

Since: ArcGIS Maps SDK for JavaScript 4.27 SceneView since 4.0, openPopup added at 4.27.

Opens the popup at the given location with content defined either explicitly with content or driven from the PopupTemplate of input features. This method sets the popup's visible property to true. Users can alternatively open the popup by directly setting the visible property to true.

A Popup instance is created and assigned to popup the first time openPopup() is called, unless popup is null. The popup then processes the click event.

When calling this method, to prevent the popup from opening when clicking on the view, set popupEnabled to false to stop event propagation on the view.

The popup will only display if the view's size constraints in dockOptions are met or the location property is set to a geometry.

Parameters
Specification

features Graphic[]
optional

Sets the popup's features, which populate the title and content of the popup based on each graphic's PopupTemplate.

promises Promise[]
optional

Sets pending promises on the popup. The popup will display once the promises resolve. Each promise must resolve to an array of Graphics.

featureMenuOpen Boolean
optional
Default Value: false

This property enables multiple features in a popup to display in a list rather than displaying the first selected feature. Setting this to true allows the user to scroll through the list of features returned from the query and choose the selection they want to display within the popup.

updateLocationEnabled Boolean
optional
Default Value: false

When true, indicates the popup should update its location for each paginated feature based on the selectedFeature's geometry.

collapsed Boolean
optional
Default Value: false

When true, indicates that only the popup header will display.

shouldFocus Boolean
optional
Default Value: false

When true, indicates that the focus should be on the popup after it has been opened.

Returns

Type Definitions

EasingFunction

Type Definition
EasingFunction(t, duration){Number}

User provided easing function. The function receives a normalized time between 0 and 1 as input and should provide a transformed normalized time between 0 and 1 as output.

Parameters
t Number

The input time (from 0 to 1)

duration Number

The total duration (in milliseconds) of the animation. This may be used for heuristics on deciding what type of easing to perform.

Returns

speedFactor Number
optional
Default Value:1

Increases or decreases the animation speed by the specified factor. A speedFactor of 2 will make the animation twice as fast, while a speedFactor of 0.5 will make the animation half as fast. Setting the speed factor will automatically adapt the default maxDuration accordingly.

duration Number
optional

Set the exact duration (in milliseconds) of the animation. Note that by default, animation duration is calculated based on the time required to reach the target at a constant speed. Setting duration overrides the speedFactor option. Note that the resulting duration is still limited to the maxDuration.

maxDuration Number
optional
Default Value:8000

The maximum allowed duration (in milliseconds) of the animation. The default maxDuration value takes the specified speedFactor into account.

optional
