Property Overview

Property Details

ambientOcclusionEnabled Boolean

Indicates whether to show ambient occlusion shading.

Default Value:false

cameraTrackingEnabled Boolean

Indicates whether the date and time of the simulated sun is automatically updated to maintain the current time of day while the camera changes.

Default Value:true

date Date

The current date and time of the simulated sun. When setting the date, specifying the time zone is important, otherwise the time zone of the browser will be used. This might lead to different lighting for users in different time zones.

Default Value:new Date("March 15, 2022 12:00:00 UTC")

declaredClass Stringreadonly inherited

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

directShadowsEnabled Boolean inherited

Indicates whether to show shadows cast by the sun. 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

displayUTCOffset Number inherited

The UTC time zone offset in hours that should be displayed in the UI to represent the date. This value does not have an impact on the actual lighting of the scene.

Default Value:null

type Stringreadonly inherited

Indicates that the light source is simulated position of the sun.

For SunLighting the type is always "sun".

waterReflectionEnabled Boolean

Indicates whether WaterSymbol3DLayer display reflections of surrounding terrain, buildings and other 3D objects.

Default Value:false

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.

clone(){SunLighting}inherited

Creates a deep clone of this object.

Returns

Type	Description

cloneWithWebsceneLighting()

Create a clone of this while partially applying the provided webscene lighting settings.

hasHandles(groupKey){Boolean}inherited

Since: ArcGIS Maps SDK for JavaScript 4.25

Returns true if a named group of handles exist.

Parameter

groupKey * optional A group key.

Returns

Type	Description
Boolean	Returns true if a named group of handles exist.

removeHandles(groupKey)inherited

Since: ArcGIS Maps SDK for JavaScript 4.25

Removes a group of handles owned by the object.

Parameter

groupKey * optional A group key or an array or collection of group keys to remove.

Example

obj.removeHandles(); // removes handles from default group

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