Inheritance: PointCloudFilter Accessor

Point cloud filters are used to hide points that do not satisfy the filter criteria.

There are two types of filters that can be assigned to PointCloudLayer.filters:

PointCloudValueFilter is useful for filtering points based on their classification value. If only the points that represent ground and buildings should be displayed, the following filter can be set:

const pcLayer = new PointCloudLayer({
  ...,
  filters: [{
    type: "value",
    field: "CLASS_CODE",
    mode: "include",
    // values include ground(2) and building(6)
    values: [2, 6]
  }]
});

PointCloudReturnFilter is used to filter points based on the return value stored with each point in the RETURNS field. The following filter can be set to display only the points that represent the highest feature in a landscape:

const pointCloudLayer = new PointCloudLayer({
 ...,
 filters: [{
   type: "return",
   field: "RETURNS",
   values: ["firstOfMany", "single"]
 }]
});

Filters can also be combined by setting several filters on one layer. Only points that satisfy all filters are displayed.

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 }
);

// Handle gets removed when the object is destroyed.
this.addHandles(handle);
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.

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
