PointCloudUniqueValueRenderer

Property Overview

Property Details

colorModulation Object inherited

Since: ArcGIS Maps SDK 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.

minValue Number optional Default Value:0 Field value at which the point color becomes darkest.

maxValue Number optional Default Value:255 Field value at which the point color will be left unchanged.

colorUniqueValueInfos Object[]

Each element in the array is an object that matches a unique value with a specific color. Features with equal values to those specified here will be assigned the associated color. For example, you may choose to visualize points representing low vegetation with a green color and points representing power lines with a gray color. Each object has the following specification:

Properties

values String[] A unique combination of values that will be represented with the given color.

color Color The color used to represent points whose value matches values.

label String optional Label used to describe points matched to the unique value.

declaredClass Stringreadonly inherited

Since: ArcGIS Maps SDK for JavaScript 4.7

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

field String

The name of the field whose values are used to drive the visualization.

fieldTransformType String

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

legendOptions Object

Since: ArcGIS Maps SDK for JavaScript 4.6

An object providing options for displaying the renderer in the Legend.

Property

title String optional 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: "Classification (high/low)"
};

pointSizeAlgorithm Object inherited

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 is splat.

Properties

type String fixed-size or splat. Choosing fixed-size implies setting size and useRealWorldSymbolSizes. If splat is chosen then scaleFactor should be set. Possible Values:"fixed-size"|"splat"

useRealWorldSymbolSizes Boolean optional Specifies whether size is in real world units or screen-space units. Applies to fixed-size only.

size Number optional Point size in meters (useRealWorldSymbolSizes = true) or points. Applies to fixed-size only.

scaleFactor Number optional Default Value:1 Specifies the scale factor that is applied to the size estimated by the density. Applies to splat only.

pointsPerInch Number inherited

The number of points to draw per display inch. This property determines the level of detail in the visualization.

Default Value:10

type Stringreadonly

The type of Renderer.

For PointCloudUniqueValueRenderer the type is always "point-cloud-unique-value".

Method Overview

Method Details

addHandles(handleOrHandles, groupKey)inherited

Since: ArcGIS Maps SDK for JavaScript 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(){PointCloudUniqueValueRenderer}

Since: ArcGIS Maps SDK for JavaScript 4.4

Creates a deep clone of the renderer.

Returns

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

Example

// Creates a deep clone of the first layer's renderer
let 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 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(groupKey){Boolean}inherited

Since: ArcGIS Maps SDK for JavaScript 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(groupKey)inherited

Since: ArcGIS Maps SDK for JavaScript 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.

Example

obj.removeHandles(); // removes handles from default group

obj.removeHandles("handle-group");
obj.removeHandles("other-handle-group");

toJSON(){Object}inherited

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.
