Public Member Functions inherited from CesiumQuantizedMeshTerrain::LayerSpec
int64_t	getSizeBytes () const
	Calculates the size in bytes of this object, including the contents of all collections, pointers, and strings. This will NOT include the size of any extensions attached to the object. Calling this method may be slow as it requires traversing the object's entire structure.
Public Member Functions inherited from CesiumUtility::ExtensibleObject
template<typename T >
bool	hasExtension () const noexcept
	Checks if an extension exists given its static type.
template<typename T >
const T *	getExtension () const noexcept
	Gets an extension given its static type.
template<typename T >
T *	getExtension () noexcept
	Gets an extension given its static type.
const JsonValue *	getGenericExtension (const std::string &extensionName) const noexcept
	Gets a generic extension with the given name as a CesiumUtility::JsonValue.
JsonValue *	getGenericExtension (const std::string &extensionName) noexcept
	Gets a generic extension with the given name as a CesiumUtility::JsonValue.
template<typename T , typename... ConstructorArgumentTypes>
T &	addExtension (ConstructorArgumentTypes &&... constructorArguments)
	Adds a statically-typed extension to this object.
template<typename T >
void	removeExtension ()
	Removes a statically-typed extension from this object.
int64_t	getSizeBytes () const
	Calculates the size in bytes of this ExtensibleObject, including all of its extras but NOT including its extensions. Calling this method may be slow as it requires traversing the entire object.

Additional Inherited Members
Public Attributes inherited from CesiumQuantizedMeshTerrain::LayerSpec
std::string	attribution
	The attribution (credit) string for the terrain.
std::vector< std::vector< CesiumQuantizedMeshTerrain::AvailabilityRectangle > >	available
	The tile availability information. The outer array is indexed by tile level. The inner array is a list of rectangles of availability at that level. Tiles themselves may also contain further availability information for their subtree.
std::vector< double >	bounds = {-180, -90, 180, 90}
	The bounding box of the terrain, expressed as west, south, east, north in degrees.
std::string	description
	The description of this terrain tileset.
std::vector< std::string >	extensionsProperty
	The extensions available for this tileset.
std::string	format = "quantized-mesh-1.0"
	The format of the terrain tiles. Should be "quantized-mesh-1.0".
int64_t	maxzoom = int64_t()
	The maximum level for which there are any available tiles.
int64_t	minzoom = 0
	The minimum level for which there are any available tiles.
std::optional< int64_t >	metadataAvailability
	The levels at metadata is found in tiles. For example, if this value is 10, then metadata is found at levels 0, 10, 20, etc.
std::string	name = "Terrain"
	The name of this terrain tileset.
std::optional< std::string >	parentUrl
	The URL of the parent layer.json that this one is layered on top of.
std::string	projection = "EPSG:4326"
	The map projection of this tileset. Valid values are "EPSG:4326" and "EPSG:3857".
std::string	scheme = "tms"
	The tiling scheme. The only valid value is "tms".
std::vector< std::string >	tiles
	The URL templates from which to obtain tiles.
std::string	version = "1.0.0"
	The version of this tileset.
Public Attributes inherited from CesiumUtility::ExtensibleObject
std::unordered_map< std::string, std::any >	extensions
	The extensions attached to this object.
JsonValue::Object	extras
	Application-specific data.
JsonValue::Object	unknownProperties
	Unknown properties that exist on this object but do not have any representation in the statically-typed classes.
Static Public Attributes inherited from CesiumQuantizedMeshTerrain::LayerSpec

Member Function Documentation

getProjection()

std::optional< CesiumGeospatial::Projection > CesiumQuantizedMeshTerrain::Layer::getProjection ( const CesiumGeospatial::Ellipsoid & ellipsoid = CesiumGeospatial::Ellipsoid::WGS84 ) const

noexcept

Gets the projection specified by this layer.json.

Returns

The projection, or std::nullopt if this layer.json does not specify a valid projection.

getRootBoundingRegion()

std::optional< CesiumGeospatial::BoundingRegion > CesiumQuantizedMeshTerrain::Layer::getRootBoundingRegion ( const CesiumGeospatial::Ellipsoid & ellipsoid = CesiumGeospatial::Ellipsoid::WGS84 ) const

noexcept

Gets the bounding region for the root tile.

The rectangle will be the maximum rectangle for the terrain's projection (geographic or web mercator). The heights will range from -1000.0 to 9000.0.

Returns

The bounding rectangle, or std::nullopt if the bounding region cannot be determined from this layer.json.

getTilingScheme()

std::optional< CesiumGeometry::QuadtreeTilingScheme > CesiumQuantizedMeshTerrain::Layer::getTilingScheme ( const CesiumGeospatial::Ellipsoid & ellipsoid = CesiumGeospatial::Ellipsoid::WGS84 ) const

noexcept

Gets the tiling scheme specified by this layer.json.

Returns

The tiling scheme, or std::nullopt if this layer.json does not specify a tiling scheme.
