readonlyinherited Property

Type: string

Inherited from: Accessor

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

directShadowsEnabled

Property

Type: boolean

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.castShadows,

FillSymbol3DLayer.castShadows, ExtrudeSymbol3DLayer.castShadows, and PathSymbol3DLayer.castShadows.

Default value: false

glow

autocast Property

Type: Glow | null | undefined

Adds a glow effect to the scene intended for stylistic visualizations. When set, this property creates a halo around light emitters, making them appear brighter and more prominent. Accepts a Glow instance or null to disable the effect.

Example:

scene.environment.lighting.glow = new Glow({ intensity: 1 });

type

readonly Property

Type: "virtual"

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.

inheritedstatic Method

Signature: fromJSON (json: any): any

Inherited from: JSONSupportMixin

Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product. The object passed into the input json parameter often comes from a response to a query operation in the REST API or a toJSON() method from another ArcGIS product. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.

Parameters

Parameter	Type	Description	Required
json	`any`	A JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects.

Returns: any

Method

Signature: clone (): VirtualLighting

Creates a deep clone of this object.

Returns: VirtualLighting
Creates a new clone of the instance calling this method.

toJSON

inherited Method

Signature: toJSON (): any

Inherited from: JSONSupportMixin
