I3SDataProvider

open external class I3SDataProvider(options: I3SDataProvider.ConstructorOptions)(source)

An I3SDataProvider is the main public class for I3S support. The url option should return a scene object. Currently supported I3S versions are 1.6 and 1.7/1.8 (OGC I3S 1.2). I3SFeature and I3SNode classes implement the Object Model for I3S entities, with public interfaces.

try {
  const i3sData = await I3SDataProvider.fromUrl(
    "https://tiles.arcgis.com/tiles/z2tnIkrLQ2BRzr6P/arcgis/rest/services/Frankfurt2017_vi3s_18/SceneServer/layers/0"
  );
  viewer.scene.primitives.add(i3sData);
} catch (error) {
  console.log(`There was an error creating the I3S Data Provider: ${error}`);
}

try {
  const geoidService = await ArcGISTiledElevationTerrainProvider.fromUrl(
    "https://tiles.arcgis.com/tiles/z2tnIkrLQ2BRzr6P/arcgis/rest/services/EGM2008/ImageServer"
  );
  const i3sData = await I3SDataProvider.fromUrl(
    "https://tiles.arcgis.com/tiles/z2tnIkrLQ2BRzr6P/arcgis/rest/services/Frankfurt2017_vi3s_18/SceneServer/layers/0", {
      geoidTiledTerrainProvider: geoidService
  });
  viewer.scene.primitives.add(i3sData);
} catch (error) {
  console.log(`There was an error creating the I3S Data Provider: ${error}`);

Parameters

options

An object describing initialization options

Constructors

I3SDataProvider

constructor(options: I3SDataProvider.ConstructorOptions)

Types

Companion

external object Companion

ConstructorOptions

external interface ConstructorOptions

Initialization options for the I3SDataProvider constructor

Properties

adjustMaterialAlphaMode

external val adjustMaterialAlphaMode: Boolean

Determines if the alpha mode of the material will be adjusted depending on the color vertex attribute.

applySymbology

external val applySymbology: Boolean

Determines if the I3S symbology will be parsed and applied for the layers.

calculateNormals

external val calculateNormals: Boolean

Determines if the flat normals will be generated for I3S geometry without normals.

data

external val data: JsAny

Gets the I3S data for this object.

extent

external val extent: Rectangle

Gets the extent covered by this I3S.

geoidTiledTerrainProvider

external val geoidTiledTerrainProvider: ArcGISTiledElevationTerrainProvider

The terrain provider referencing the GEOID service to be used for orthometric to ellipsoidal conversion.

layers

external val layers: ReadonlyArray<I3SLayer>

Gets the collection of layers.

name

external val name: String

Gets a human-readable name for this dataset.

resource

external val resource: Resource

The resource used to fetch the I3S dataset.

show

external var show: Boolean

Determines if the dataset will be shown.

showFeatures

external val showFeatures: Boolean

Determines if the features will be shown.

sublayers

external val sublayers: ReadonlyArray<I3SSublayer>

Gets the collection of building sublayers.

Functions

destroy

external fun destroy()

Destroys the WebGL resources held by this object. Destroying an object allows for deterministic release of WebGL resources, instead of relying on the garbage collector to destroy this object.
