PointCloudClassBreaksRenderer
require(["esri/renderers/PointCloudClassBreaksRenderer"], function(PointCloudClassBreaksRenderer) { /* code goes here */ });
esri/renderers/PointCloudClassBreaksRenderer
This class defines the color of each point in a PointCloudLayer based on the value of a numeric attribute. Colors are assigned based on classes or ranges of data. Each point is assigned a symbol based on the class break in which the value of the attribute falls.
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.

Property Details
- colorClassBreakInfosObject[]
Each element in the array is an object that provides information about a class break associated with the renderer. Each object has the following specification:
- Since: ArcGIS API for JavaScript 4.4
Reduces the brightness of the point's color, based on the value of another field, usually
intensity
. High values leave the color unchanged, while low values darken the color of the point. This helps to display the scanned surface in a more realistic way.- Properties:
- field String
Field to use for the color modulation. Commonly modulation is used with the
intensity
field.optionalminValue NumberDefault Value:0Field value at which the point color becomes darkest.
optionalmaxValue NumberDefault Value:255Field value at which the point color will be left unchanged.
- See also:
- Since: ArcGIS API for JavaScript 4.7
The name of the class. The declared class name is formatted as
esri.folder.className
.
- fieldString
The name of the field that is used to drive the color visualization for the renderer. The value of this field determines which class break each point is assigned.
- fieldTransformTypeString
A transform that is applied to the field value before evaluating the renderer.
Possible Values: none | low-four-bit | high-four-bit | absolute-value | modulo-ten
- Default Value:null
- legendOptionsObjectSince: ArcGIS API for JavaScript 4.6
An object providing options for displaying the renderer in the Legend.
- Property:
- optionaltitle String
Describes the variable driving the visualization. This is displayed as the title of the corresponding renderer in the Legend and takes precedence over a field alias.
Example:renderer.legendOptions = { title: "Density" };
Specifies how the size of the points in the point cloud is computed for rendering.
The splat algorithm automatically computes a size based on the density, which varies with the Level of Detail that is currently displayed.
The fixed size algorithm displays all points with the same size, either in screen space or real world units.
When
pointSizeAlgorithm
is not set, the default issplat

Method Details
- clone(){PointCloudClassBreaksRenderer}
Creates a deep clone of the renderer.
Returns:Type Description PointCloudClassBreaksRenderer A deep clone of the object that invoked this method. Example:// Creates a deep clone of the first layer's renderer var renderer = view.map.layers.getItemAt(0).renderer.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 ObjectA 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.
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.
