I3SDataProvider

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

object Companion

ConstructorOptions

interface ConstructorOptions

Initialization options for the I3SDataProvider constructor

Properties

adjustMaterialAlphaMode

val adjustMaterialAlphaMode: Boolean

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

applySymbology

val applySymbology: Boolean

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

calculateNormals

val calculateNormals: Boolean

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

data

val data: Any

Gets the I3S data for this object.

extent

val extent: Rectangle

Gets the extent covered by this I3S.

geoidTiledTerrainProvider

val geoidTiledTerrainProvider: ArcGISTiledElevationTerrainProvider

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

layers

val layers: ReadonlyArray<I3SLayer>

Gets the collection of layers.

name

val name: String

Gets a human-readable name for this dataset.

resource

val resource: Resource

The resource used to fetch the I3S dataset.

show

var show: Boolean

Determines if the dataset will be shown.

showFeatures

val showFeatures: Boolean

Determines if the features will be shown.

sublayers

val sublayers: ReadonlyArray<I3SSublayer>

Gets the collection of building sublayers.

Functions

destroy

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.
