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 line 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.

Autocasting support

As of version 4.5 of the ArcGIS API for JavaScript, autocasting is universally supported for all renderers, symbols, and symbol layers in the API. So there is no need to include this module in the require() and define() module loaders of your application unless you intend to use the static method(s) of this module.

• Sample - SceneLayer

• SimpleRenderer
• UniqueValueRenderer
• Graphic

Example:

var 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
};

Constructors

new MeshSymbol3D(properties)

Parameter:

properties Object optional See the properties for a list of all the properties that may be passed into the constructor.

Property Overview

Property Details

declaredClassStringreadonly inherited

Since: ArcGIS API for JavaScript 4.7

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

styleOriginObject inherited

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.

Properties:

styleName String optional a well-known esri-provided style, such as EsriThematicShapesStyle

styleUrl String optional url to a style definition

name String name of the symbol in the style referenced by styleName or styleUrl

symbolLayersCollection<Symbol3DLayer>autocast inherited

Autocasts from Object[]

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.

typeStringreadonly

For MeshSymbol3D, the type is always mesh-3d.

Method Overview

Method Details

clone(){MeshSymbol3D}

Creates a deep clone of the symbol.

Returns:

Type	Description
MeshSymbol3D	A deep clone of the object that invoked this method.

Example:

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

fromJSON(json){*}static

Creates a new instance of this class and initializes it with values from a JSON object generated from a product in the ArcGIS platform. 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}inherited

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

Returns:

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