Interface TerrainProvider

All Known Implementing Classes:

ArcGISTiledElevationTerrainProvider, CesiumTerrainProvider, EllipsoidTerrainProvider, GeoserverTerrainProvider, GoogleEarthEnterpriseTerrainProvider, VRTheWorldTerrainProvider

@JsType(isNative=true,
        namespace="Cesium",
        name="TerrainProvider")
public interface TerrainProvider

Provides terrain or other geometry for the surface of an ellipsoid. The surface geometry is organized into a pyramid of tiles according to a TilingScheme. This type describes an interface and is not intended to be instantiated directly.

Method Summary

Modifier and Type	Method and Description
double	getLevelMaximumGeometricError(int level) Gets the maximum geometric error allowed in a tile at a given level.
boolean	getTileDataAvailable(int x, int y, int level) Determines whether data for a tile is available to be loaded.
Promise<TerrainData,Void>	requestTileGeometry(int x, int y, int level, Request request) Requests the geometry for a given tile.

Method Detail

getLevelMaximumGeometricError

@JsMethod
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.

Parameters:

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

Returns:

The maximum geometric error.

getTileDataAvailable

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

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

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
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.

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.
