Cesium config parameters

To configure an hslayers-ng project with a cesium 3D map, an extra configuration must be specified similarly like for a simple hslayers-ng base map project. Either in the main application file (usually app.component.ts's constructor) using this.hsCesiumConfig.update(...) method.

Example:

constructor(private hsCesiumConfig: HsCesiumConfig) {
this.hsCesiumConfig.update({
    terrain_provider: 'https://assets.agi.com/stk-terrain/v1/tilesets/world/tiles',
    terrain_providers: [{
        title: 'EU-DEM',
        url: 'https://assets.agi.com/stk-terrain/v1/tilesets/world/tiles',
        active: true
    }],

Or in the hslayersCesiumConfig() function in case of the "simple" application.

Example:

function hslayersCesiumConfig() {
  return {
    terrain_provider: 'https://assets.agi.com/stk-terrain/v1/tilesets/world/tiles',
    terrain_providers: [{
        title: 'EU-DEM',
        url: 'https://assets.agi.com/stk-terrain/v1/tilesets/world/tiles',
        active: true
    }],

Cesium 3D Maps

Property	Type	Manditory	Default Value	Description	Example
cesiumAccessToken	String	true		Access token for Cesium. Register for it here: https://cesium.com/ion/assets/.
cesiumAnimation	Boolean	true		Should Cesium animate 3D objects.
cesiumBase	String	true		Directory of Cesium library. Example: ./node_modules/cesium/Build/Cesium/.
cesiumBingKey	String	true		API key for Bing maps used as Cesium base layer. See: https://www.bingmapsportal.com/.
cesiumDebugShowFramesPerSecond	Boolean	true		Turn on or off FPS counter which is used for performance benchmarking.
cesiumInfoBox	Boolean	true		Show 'get feature info' results in Cesium interface.
cesiumShadows	Boolean	true		Show shadows for objects and terrain.
cesiumTime	Cesium.JulianDate	true		Cesium.JulianDate class object which specifies default time value... to set Cesium viewer.clockViewModel.currentTime to. See: https://cesiumjs.org/Cesium/Build/Documentation/JulianDate.html.
cesiumTimeline	Boolean	true		Turn on or off Cesium timeline.
creditContainer	Element | String	false		The DOM element or ID that will contain the CreditDisplay... If not specified, the credits are added to the bottom of the widget itself.
createWorldTerrainOptions	Object	false		If no terrain_provider config parameter is present... , then createWorldTerrainOptions object is used in Cesium.createWorldTerrain function to create terrain layer. See: https://cesiumjs.org/Cesium/Build/Documentation/createWorldTerrain.html.
imageryProvider	Cesium.ImageryProvider	false		The imagery provider to use instead of default Bing maps. This value is only valid if Cesium's options.baseLayerPicker is set to false. See: https://cesiumjs.org/Cesium/Build/Documentation/ImageryProvider.html.
terrain_provider	Object	false		This is passed to viewer.terrainProvider configuration option... See: https://cesiumjs.org/Cesium/Build/Documentation/Viewer.html and https://cesiumjs.org/Cesium/Build/Documentation/TerrainProvider.html.	Example
terrain_providers	Array<Object>	false		Objects between which user will be able to choose in layer manager. See terrain_provider config option.
newTerrainProviderOptions		false		Specifies new terrain provider options for cesium map.
terrainExaggeration	Number	false		A scalar used to exaggerate the terrain... Default value is 1.0. Note that terrain exaggeration will not modify any other primitive as they are positioned relative to the ellipsoid.

terrain_provider example:

new Cesium.CesiumTerrainProvider({
        url : Cesium.IonResource.fromAssetId(3956),
        requestVertexNormals : true
    })
