Symbol3DLayer

Class: esri/symbols/Symbol3DLayer
Inheritance: Symbol3DLayer Accessor
Since: ArcGIS API for JavaScript 4.0

Symbol layers are used to define the visualization of Point, Polyline, Polygon, and mesh geometries rendered with 3D symbols. 3D symbols may only be used to render features in a FeatureLayer, SceneLayer, or standalone graphics in a 3D SceneView. There is no support for 3D symbols in 2D MapViews.

All 3D symbols have a symbolLayers property, which is an array of Symbol3DLayer objects. All symbols must have at least one symbol layer added to the symbolLayers property. Think of the symbol object as a container that holds multiple symbol layers which define the appearance of the symbol. One layer may be an outline, another the fill, etc. The relationship of symbol layers to symbol is similar to the relationship of operational layers to a Map.

Each symbol layer type may only be applied to certain Symbol3D and Geometry types. See the table below to learn more about when to use each type of symbol layer.

Symbol3DLayer Type Symbol3D Type Flat/Volumetric Size Units Example
IconSymbol3DLayer PointSymbol3D, PolygonSymbol3D flat points s3d-icon-circle
ObjectSymbol3DLayer PointSymbol3D, PolygonSymbol3D volumetric meters s3d-object
LineSymbol3DLayer LineSymbol3D, PolygonSymbol3D flat points s3d-line
PathSymbol3DLayer LineSymbol3D volumetric meters s3d-path
FillSymbol3DLayer PolygonSymbol3D, MeshSymbol3D flat - s3d-fill
WaterSymbol3DLayer PolygonSymbol3D flat - s3d-water
ExtrudeSymbol3DLayer PolygonSymbol3D volumetric meters s3d-extrusion
TextSymbol3DLayer PointSymbol3D, PolygonSymbol3D, LabelSymbol3D flat points s3d-text

The size of flat symbol layers is usually defined in either points or pixels (screen space) whereas the size of volumetric symbol layers is defined in meters (real-world space).

Method Details

fromJSON(json){*}static

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.

Parameter:
json Object

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:
Type Description
* Returns a new instance of this class.
toJSON(){Object}

Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.

Returns:
Type Description
Object The ArcGIS portal JSON representation of an instance of this class.
