The VirtualLighting class allows you to change the lighting in the scene to virtual light. The position of the light follows the camera and has a slight top-right offset in respect to the camera.
Example:
let view = new SceneView({
container: "viewDiv",
map: new Map({
basemap: "satellite",
ground: "world-elevation"
}),
environment: {
lighting: {
type: "virtual" // autocasts as new VirtualLighting()
}
}
});
The lighting visualization updates as soon as the type property changes:
view.environment.lighting = {
type: "virtual",
directShadowsEnabled: true // autocasts as new VirtualLighting({ directShadowsEnabled: true })
}

Boolean | Indicates whether to show ambient occlusion shading. more details | VirtualLighting | |
String | The name of the class. more details | Accessor | |
Boolean | Indicates whether to show shadows cast by the light source. more details | VirtualLighting | |
String | Indicates that the light source is virtual light. more details | VirtualLighting | |
Boolean | Indicates whether WaterSymbol3DLayer display reflections of surrounding terrain, buildings and other 3D objects. more details | VirtualLighting |
Property Details
-
ambientOcclusionEnabled BooleanDeprecated since version 4.27. Ambient occlusion is automatically shown and this property has no effect.
-
Indicates whether to show ambient occlusion shading.
- Default Value:false
-
The name of the class. The declared class name is formatted as
esri.folder.className
.
-
Indicates whether to show shadows cast by the light source. Shadows are only displayed for real world 3D objects. Terrain doesn't cast shadows. In local scenes at small zoom levels, shadows are not displayed. For more control on which 3D objects cast shadows use the
castShadows
property available on ObjectSymbol3DLayer,FillSymbol3DLayer, ExtrudeSymbol3DLayer, and PathSymbol3DLayer.
- Default Value:false
-
Indicates that the light source is virtual light. Virtual light is top - right position respect to the camera enabling user to observe the scene independant to the possition of the sun.
For VirtualLighting the type is always "virtual".
-
waterReflectionEnabled BooleanDeprecated since version 4.27. Reflections are automatically shown and this property has no effect.
-
Indicates whether WaterSymbol3DLayer display reflections of surrounding terrain, buildings and other 3D objects.
- Default Value:false

Method Details
-
addHandles(handleOrHandles, groupKey)inheritedSince: ArcGIS Maps SDK for JavaScript 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();
ParametershandleOrHandles WatchHandle|WatchHandle[]Handles marked for removal once the object is destroyed.
groupKey *optionalKey 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.

-
Creates a deep clone of this object.
ReturnsType Description VirtualLighting Creates a new clone of the instance calling this method.
-
cloneWithWebsceneLighting()
-
Create a clone of this while partially applying the provided webscene lighting settings.

Returns true if a named group of handles exist.
ParametergroupKey *optionalA group key.
ReturnsType Description Boolean Returns true
if a named group of handles exist.Example// Remove a named group of handles if they exist. if (obj.hasHandles("watch-view-updates")) { obj.removeHandles("watch-view-updates"); }
-
removeHandles(groupKey)inheritedSince: ArcGIS Maps SDK for JavaScript 4.25
-
Removes a group of handles owned by the object.
ParametergroupKey *optionalA group key or an array or collection of group keys to remove.
Exampleobj.removeHandles(); // removes handles from default group obj.removeHandles("handle-group"); obj.removeHandles("other-handle-group");
