A TerrainProvider that produces terrain geometry by tessellating height maps retrieved from a VT MÄK VR-TheWorld server.

Parameters:
Name Type Argument Default Description
description.url String The URL of the VR-TheWorld TileMap.
description.proxy Object <optional>
 A proxy to use for requests. This object is expected to have a getURL function which returns the proxied URL, if needed.
description.ellipsoid Ellipsoid <optional>
 Ellipsoid.WGS84 The ellipsoid. If this parameter is not specified, the WGS84 ellipsoid is used.
description.credit Credit | String <optional>
 A credit for the data source, which is displayed on the canvas.
Example

Members

:Credit

Gets the credit to display when this terrain provider is active. Typically this is used to credit the source of the terrain. This function should not be called before VRTheWorldTerrainProvider#ready returns true.

:Event

Gets an event that is raised when the terrain provider encounters an asynchronous error. By subscribing to the event, you will be notified of the error and can potentially recover from it. Event listeners are passed an instance of TileProviderError.

:Boolean

Gets a value indicating whether or not the provider is ready for use.

:GeographicTilingScheme

Gets the tiling scheme used by this provider. This function should not be called before VRTheWorldTerrainProvider#ready returns true.

Methods

Gets the maximum geometric error allowed in a tile at a given level.

Parameters:
Name Type Description
level Number The tile level for which to get the maximum geometric error.
Returns:
Number The maximum geometric error.

Gets a value indicating whether or not the provider includes a water mask. The water mask indicates which areas of the globe are water rather than land, so they can be rendered as a reflective surface with animated waves.

Returns:
Boolean True if the provider has a water mask; otherwise, false.

Requests the geometry for a given tile. This function should not be called before ArcGisImageServerTerrainProvider#ready returns true. The result includes terrain data and indicates that all child tiles are available.

Parameters:
Name Type Argument Default Description
x Number The X coordinate of the tile for which to request geometry.
y Number The Y coordinate of the tile for which to request geometry.
level Number The level of the tile for which to request geometry.
throttleRequests Boolean <optional>
 true True if the number of simultaneous requests should be limited, or false if the request should be initiated regardless of the number of requests already in progress.
Returns:
Promise | TerrainData A promise for the requested geometry. If this method returns undefined instead of a promise, it is an indication that too many requests are already pending and the request will be retried later.
