PointSymbol3D | API Reference | ArcGIS Maps SDK for JavaScript 4.30

PointSymbol3D is used to render features with Point geometry in a 3D SceneView. This symbol type is not supported in 2D MapViews.

A PointSymbol3D must include at least one symbol layer for it to render in the view. One or more of the following symbol layer types must be used to define a 3D point symbol:

Symbol3DLayer Type	Flat/Volumetric	Size Units
IconSymbol3DLayer	flat	points
ObjectSymbol3DLayer	volumetric	meters
TextSymbol3DLayer	flat	points

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: "point-3d",  // autocasts as new PointSymbol3D()
  symbolLayers: [{
    type: "object",  // autocasts as new ObjectSymbol3DLayer()
    width: 5,    // diameter of the object from east to west in meters
    height: 10,  // height of object in meters
    depth: 15,   // diameter of the object from north to south in meters
    resource: { primitive: "cube" },
    material: { color: "red" }
  }]
};

Type	Summary	Class
LineCallout3D	Settings for adding a callout visualization to the symbol.	PointSymbol3D
String	The name of the class.	Accessor
StyleOrigin	The origin of the style from which the symbol was originally referenced.	Symbol3D
Collection<(IconSymbol3DLayer\|ObjectSymbol3DLayer\|TextSymbol3DLayer)>	A Collection of Symbol3DLayer objects used to visualize the graphic or feature.	PointSymbol3D
String	The symbol type.	PointSymbol3D
Symbol3DVerticalOffset	Shifts the symbol along the vertical world axis by a given height.	PointSymbol3D

Property Details

callout Property callout LineCallout3D Since: ArcGIS Maps SDK for JavaScript 4.4 PointSymbol3D since 4.0, callout added at 4.4.

Settings for adding a callout visualization to the symbol. Callouts are drawn from the point feature location that is being symbolized, to the vertical offset of the symbol. This property has no effect if verticalOffset is not set. At the moment only callouts of type line are supported. See LineCallout3D.

Example

let symbol = {
  type: "point-3d",  // autocasts as new PointSymbol3D()
  symbolLayers: [...],
  verticalOffset: ...,
  callout: {
    type: "line",  // autocasts as new LineCallout3D()
    size: 1.5,
    color: [150, 150, 150],
    border: {
      color: [50, 50, 50]
    }
  }
};

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.7 Accessor since 4.0, declaredClass added at 4.7.

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

styleOrigin Inherited Property styleOrigin StyleOrigin 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 Property symbolLayers Collection<(IconSymbol3DLayer|ObjectSymbol3DLayer|TextSymbol3DLayer)>autocast 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.

type Property type Stringreadonly

The symbol type.

For PointSymbol3D the type is always "point-3d".

verticalOffset Property verticalOffset Symbol3DVerticalOffset Since: ArcGIS Maps SDK for JavaScript 4.4 PointSymbol3D since 4.0, verticalOffset added at 4.4.

Shifts the symbol along the vertical world axis by a given height. The height is set in screen space units like points or pixels. For points displayed with a callout verticalOffset should be set.

let symbol = {
  type: "point-3d",  // autocasts as new PointSymbol3D()
  symbolLayers: [...],
  verticalOffset: {
    screenLength: 40,
    maxWorldLength: 100,

Return Type	Summary	Class
	Adds one or more handles which are to be tied to the lifecycle of the object.	Accessor
PointSymbol3D	Creates a deep clone of the symbol.	PointSymbol3D

Method Details

addHandles Inherited Method addHandles(handleOrHandles, groupKey) Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, addHandles added at 4.25.

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 Method clone(){PointSymbol3D}

Creates a deep clone of the symbol.

Returns

Type	Description
PointSymbol3D	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();

fromJSON Inherited Method 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.

hasHandles Inherited Method hasHandles(groupKey){Boolean} Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, hasHandles added at 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.

Example

// Remove a named group of handles if they exist.
if (obj.hasHandles("watch-view-updates")) {
  obj.removeHandles("watch-view-updates");
}

removeHandles Inherited Method removeHandles(groupKey) Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, removeHandles added at 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.
