Constructor & Destructor Documentation

EllipsoidTilesetLoader()

Cesium3DTilesSelection::EllipsoidTilesetLoader::EllipsoidTilesetLoader

(

const CesiumGeospatial::Ellipsoid &

ellipsoid = CesiumGeospatial::Ellipsoid::WGS84

)

Constructs a new instance.

Parameters

ellipsoid

The CesiumGeospatial::Ellipsoid.

Member Function Documentation

createTileChildren()

TileChildrenResult Cesium3DTilesSelection::EllipsoidTilesetLoader::createTileChildren ( const Tile & tile, const CesiumGeospatial::Ellipsoid & ellipsoid = CesiumGeospatial::Ellipsoid::WGS84 )

overridevirtual

Create the tile's children.

Note that: when receiving RetryLater status, client needs to load this tile's content first or its parent's content. The reason is that some tileset formats store the tile's children along with its content or store a whole subtree for every n-th level tile (e.g Quantized Mesh format). So unless the tile's content or the root tile of the subtree the tile is in is loaded, the loader won't know how to create the tile's children.

Parameters

tile	The tile to create children for.
ellipsoid	The CesiumGeospatial::Ellipsoid.

Returns

The TileChildrenResult that stores the tile's children

Implements Cesium3DTilesSelection::TilesetContentLoader.

createTileset()

static std::unique_ptr< Tileset > Cesium3DTilesSelection::EllipsoidTilesetLoader::createTileset ( const TilesetExternals & externals, const TilesetOptions & options = TilesetOptions{} )

static

Creates a new tileset with this loader.

Parameters

externals	The external interfaces to use.
options	Additional options for the tileset.

getHeightSampler()

ITilesetHeightSampler * Cesium3DTilesSelection::EllipsoidTilesetLoader::getHeightSampler ( )

overridevirtual

Gets an interface that can be used to efficiently query heights from this tileset.

Some loaders may be able to query heights very efficiently by using a web service or by using an analytical model, e.g., when the "terrain" is a simple ellipsoid.

For loaders that have no particular way to query heights, this method will return nullptr, signaling that heights should be computed by downloading and sampling individual tiles.

Returns

The interface that can be used to efficiently query heights from this loader, or nullptr if this loader has no particular way to do that. The returned instance must have a lifetime that is at least as long as the loader itself.

Reimplemented from Cesium3DTilesSelection::TilesetContentLoader.

loadTileContent()

CesiumAsync::Future< TileLoadResult > Cesium3DTilesSelection::EllipsoidTilesetLoader::loadTileContent ( const TileLoadInput & input )

overridevirtual

Load the tile content.

Parameters

input

The TileLoadInput that has the tile info and loading systems to load this tile's content

Returns

The future of TileLoadResult that stores the tile's content

Implements Cesium3DTilesSelection::TilesetContentLoader.

sampleHeights()

CesiumAsync::Future< SampleHeightResult > Cesium3DTilesSelection::EllipsoidTilesetLoader::sampleHeights ( const CesiumAsync::AsyncSystem & asyncSystem, std::vector< CesiumGeospatial::Cartographic > && positions )

overridevirtual

Queries the heights at a list of locations.

Parameters

asyncSystem	The async system used to do work in threads.
positions	The positions at which to query heights. The height field of each CesiumGeospatial::Cartographic is ignored.

Returns

A future that will be resolved when the heights have been queried.

Implements Cesium3DTilesSelection::ITilesetHeightSampler.
