Inheritance:: PointCloudUniqueValueRenderer→PointCloudRenderer→Accessor

Since: ArcGIS Maps SDK for JavaScript 4.2

PointCloudUniqueValueRenderer allows you to colorize points in a PointCloudLayer based on an attribute value. This is done by assigning unique colors to represent points with equal attribute values. This renderer is used to visualize points of the same type, not interpolate colors along a continuous ramp mapped to numbers.

colorModulation

autocast inherited Property

Type: ColorModulation

Inherited from: PointCloudRenderer

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.

colorUniqueValueInfos

autocast Property

Type: ColorUniqueValueInfo[] | null | undefined

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:

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.

field

Property

Type: string | null | undefined

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

fieldTransformType

Property

Type: FieldTransformType | null | undefined

A transform that is applied to the field value before evaluating the renderer.

legendOptions

autocast Property

Type: RendererLegendOptions | null | undefined

Since: ArcGIS Maps SDK for JavaScript 4.6

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

Example

renderer.legendOptions = {
  title: "Classification (high/low)",
  order: "descending-values",
};

pointSizeAlgorithm

autocast inherited Property

Type: PointSizeFixedSizeAlgorithm | PointSizeSplatAlgorithm

Inherited from: PointCloudRenderer

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.

pointsPerInch

inherited Property

Type: number

Inherited from: PointCloudRenderer

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

Default value: 10

type

readonly Property

Type: "point-cloud-unique-value"

The type of Renderer.

`clone`	`clone(): PointCloudUniqueValueRenderer`
`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 (): PointCloudUniqueValueRenderer

Since: ArcGIS Maps SDK for JavaScript 4.4

Creates a deep clone of the renderer.

Returns: 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.at(0).renderer.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.
