Inheritance:: MeshSymbol3D→Symbol3D→Symbol→Accessor

Since: ArcGIS Maps SDK for JavaScript 4.0

MeshSymbol3D is used to render 3D mesh features in a SceneLayer in a 3D SceneView. This symbol type is not supported in 2D MapViews.

A MeshSymbol3D must include at least one symbol layer for it to render in the view. One or more of the following symbol layer types may be used to define a 3D mesh symbol:

Symbol3DLayer Type	Flat/Volumetric	Size Units	Example
FillSymbol3DLayer	flat	-

The image below depicts a SceneLayer whose graphics are styled with a MeshSymbol3D containing a FillSymbol3DLayer.

See Symbol3DLayer and Symbol3D to read more general information about 3D symbols, symbol layers and how they relate to one another.

Example

let symbol = {
  type: "mesh-3d",  // autocasts as new MeshSymbol3D()
  symbolLayers: [{
    type: "fill",  // autocasts as new FillSymbol3DLayer()
    material: { color: "green" }
  }]
};
sceneLayer.renderer = {
  type: "simple",  // autocasts as new SimpleRenderer()
  symbol: symbol
};

color

inherited Property

Type: Color | null

Inherited from: Symbol3D

3D symbols do not support colors on the symbol level. Colors may be set on individual symbol layer materials instead. Setting the color property on a 3D symbol will not have any effect. The color property is present for consistency with other symbol types.

Examples

// CSS color string
symbol.color = "dodgerblue";

// HEX string
symbol.color = "#33cc33";

// array of RGBA values
symbol.color = [51, 204, 51, 0.3];

// object with rgba properties
symbol.color = {
  r: 51,
  g: 51,
  b: 204,
  a: 0.7
};

declaredClass

readonlyinherited Property

Type: string

Inherited from: Accessor

Since: ArcGIS Maps SDK for JavaScript 4.7

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

styleOrigin

autocast inherited Property

Type: StyleOrigin | null | undefined

Inherited from: Symbol3D

The origin of the style from which the symbol was originally referenced.

A reference to the style origin can be either by styleName or by styleUrl (but not both). This information is part of the WebScene persistence model and may be used to understand where a symbol was originally sourced from. It does not affect actual appearance or rendering of the symbol.

symbolLayers

autocast Property

Type: Collection<FillSymbol3DLayer>

A Collection of Symbol3DLayer objects used to visualize the graphic or feature. Individual symbol layers may be autocast as objects and specified using the type property.

type

readonly Property

Type: "mesh-3d"

The symbol type.

`clone`	`clone(): MeshSymbol3D`
`toJSON` inherited	`toJSON(): any`	JSONSupportMixin

fromJSON

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
Returns a new instance of this class.

clone

Method

Signature: clone (): MeshSymbol3D

Creates a deep clone of the symbol.

Returns: MeshSymbol3D
A deep clone of the object that invoked this method.

Example

// Creates a deep clone of the graphic's symbol
let symLyr = graphic.symbol.clone();

toJSON

inherited Method

Signature: toJSON (): any

Inherited from: JSONSupportMixin

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

Returns: any
The ArcGIS portal JSON representation of an instance of this class.
