Field Detail

credit

@JsProperty
public Credit 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 ready returns true.

errorEvent

@JsProperty
public Event errorEvent

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.

hasVertexNormals

@JsProperty
public boolean hasVertexNormals

Gets a value indicating whether or not the requested tiles include vertex normals. This function should not be called before ready returns true.

hasWaterMask

@JsProperty
public boolean hasWaterMask

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. This function should not be called before TerrainProvider#ready returns true.

ready

@JsProperty
public boolean ready

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

tilingScheme

@JsProperty
public GeographicTilingScheme tilingScheme

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

Constructor Detail

VRTheWorldTerrainProvider

@JsConstructor
public VRTheWorldTerrainProvider()

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

VRTheWorldTerrainProvider

@JsConstructor
public VRTheWorldTerrainProvider(VRTheWorldTerrainProviderOptions options)

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

Parameters:

options - VRTheWorldTerrainProviderOptions Options.

Method Detail

readyPromise

@JsProperty(name="readyPromise")
public Promise<Boolean,Void> readyPromise()

Gets a promise that resolves to true when the provider is ready for use.

getLevelMaximumGeometricError

@JsMethod
public double getLevelMaximumGeometricError(int level)

Gets the maximum geometric error allowed in a tile at a given level. This function should not be called before ready returns true.

Specified by:

getLevelMaximumGeometricError in interface TerrainProvider

Parameters:

level - The tile level for which to get the maximum geometric error.

Returns:

The maximum geometric error.

getTileDataAvailable

@JsMethod
public boolean getTileDataAvailable(int x,
                                              int y,
                                              int level)

Determines whether data for a tile is available to be loaded.

Specified by:

getTileDataAvailable in interface TerrainProvider

Parameters:

x - The X coordinate of the tile for which to request geometry.

y - The Y coordinate of the tile for which to request geometry.

level - The level of the tile for which to request geometry.

Returns:

Undefined if not supported by the terrain provider, otherwise true or false.

requestTileGeometry

@JsMethod
public Promise<TerrainData,Void> requestTileGeometry(int x,
                                                               int y,
                                                               int level,
                                                               Request request)

Requests the geometry for a given tile. This function should not be called before ready returns true. The result must include terrain data and may optionally include a water mask and an indication of which child tiles are available.

Specified by:

requestTileGeometry in interface TerrainProvider

Parameters:

x - The X coordinate of the tile for which to request geometry.

y - The Y coordinate of the tile for which to request geometry.

level - The level of the tile for which to request geometry.

request - The request object. Intended for internal use only.

Returns:

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.
