Tile class

The class that holds the tiled data for a DataSource.

Signature:

export declare class Tile implements CachedResource 

Implements: CachedResource

Constructors

Constructor	Modifiers	Description
(constructor)(dataSource, tileKey, offset, localTangentSpace)		Creates a new Tile.

Properties

Property	Modifiers	Type	Description
allGeometryLoaded	readonly	boolean	True if all geometry of the Tile has been loaded.
blockingElements	readonly	PathBlockingElement[]	Get the current blocking elements.
boundingBox	readonly	OrientedBox3	Gets the tile's bounding box.
center	readonly	THREE.Vector3	The center of this Tile in world coordinates.
copyrightInfo?		CopyrightInfo[]	(Optional) Copyright information of this Tile's data.
dataSource	readonly	DataSource
decodedTile		DecodedTile | undefined	Gets the decoded tile; it is removed after geometry handling.
delayRendering		boolean	If the tile should not yet be rendered, this is used typically when the tile in question does not fit into the gpu upload limit of the current frame. Setting this value directly affects the [[willRender]] method, unless overriden by deriving classes.
dependencies	readonly	TileKey[]	The optional list of HERE TileKeys of tiles with geometries that cross the boundaries of this Tile.
disposed	readonly	boolean	Returns true if this Tile has been disposed.
frameNumLastRequested		number	Keeping some stats for the individual Tiles to analyze caching behavior. The frame the Tile was last requested. This is required to know when the given Tile can be removed from the cache.
frameNumLastVisible		number	The last frame this Tile has been rendered (or was in the visible set). Used to determine visibility of Tile at the end of a frame, if the number is the current frame number, it is visible.
frameNumVisible		number	The frame the Tile was first visible.
geoBox	readonly	GeoBox	The bounding box of this Tile in geocoordinates.
hasGeometry	readonly	boolean	MapView checks if this Tile is ready to be rendered while culling. By default, MapView checks if the [[objects]] list is not empty. However, you can override this check by manually setting this property.
isVisible		boolean	The visibility status of the Tile. It is actually visible or planned to become visible.
levelOffset		number	Used to tell if the Tile is used temporarily as a fallback tile. levelOffset is in in the range [-quadTreeSearchDistanceUp, quadTreeSearchDistanceDown], where these values come from the VisibleTileSetOptions
localTangentSpace	readonly	boolean	Whether the data of this tile is in local tangent space or not.
m_tileGeometryLoader?	protected readonly	TileGeometryLoader	(Optional)
mapView	readonly	MapView	The MapView this Tile belongs to.
memoryUsage	readonly	number
numFramesVisible		number	After removing from cache, this is the number of frames the Tile was visible.
objects	readonly	TileObject[]	A list of the THREE.js objects stored in this Tile.
offset		number	The optional offset, this is an integer which represents what multiple of 360 degrees to shift, only useful for flat projections, hence optional.
preparedTextPaths	protected	TextPathGeometry[] | undefined	Prepared text geometries optimized for display.
projection	readonly	Projection	The currently used by the MapView.
skipRendering		boolean	If the tile should not be rendered, this is used typically when the tile in question is completely covered by another tile and therefore can be skipped without any visual impact. Setting this value directly affects the [[willRender]] method, unless overriden by deriving classes.
textElementsChanged		boolean	Gets the current modification state for the list of s in the Tile.
textStyleCache	readonly	TileTextStyleCache	Text style cache for this tile.
tileGeometryLoader	readonly	TileGeometryLoader | undefined
tileKey	readonly	TileKey
tileLoader		ITileLoader | undefined	Gets the ITileLoader that manages this tile.
uniqueKey	readonly	number	Gets the key to uniquely represent this tile (based on the and ).
visibilityCounter		number	Version stamp of the visibility set in the [[TileManager]]. If the counter is different, the visibility of the Tile's objects has to be calculated. Optimization to reduce overhead of computing visibility.
visibleArea		number	Estimated visible area of tile used for sorting the priorities during loading.

Methods

Method	Modifiers	Description
addBlockingElement(blockingElement)		Adds a PathBlockingElement to this Tile.
addOwnedTexture(texture)		Add ownership of a texture to this tile.
addTextElement(textElement)		Adds a to this Tile, which is added to the visible set of s based on the capacity and visibility.
addUserTextElement(textElement)		Adds a developer-defined to this Tile.
clear()		Frees the rendering resources allocated by this Tile.
clearTextElements()		Removes all from the tile.
computeWorldOffsetX()		Computes the offset in the x world coordinates corresponding to this tile, based on its .
didRender()		Called after MapView has rendered this Tile.
dispose()		Disposes this Tile, freeing all geometries and materials for the reachable objects.
forceHasGeometry(value)		Overrides the default value for [[hasGeometry]] if value is not undefined.
getResourceInfo()		Compute TileResourceInfo of this Tile.
hasTextElements()		Returns true if the Tile has any text elements to render.
invalidateResourceInfo()		Force invalidation of the cached TileResourceInfo.
load()		Loads this Tile geometry.
loadingFinished()	protected	Called when is finished.
raycast(rayCaster, intersects, recursive)		Performs raycasting on the tile's objects.
removeTextElement(textElement)		Removes a from this Tile.
removeUserTextElement(textElement)		Removes a developer-defined from this Tile.
resetVisibilityCounter()		Reset the visibility counter. This will force the visibility check to be rerun on all objects in this Tile.
shouldDisposeObjectGeometry(object)		Called when the default implementation of dispose() needs to free the geometry of a Tile object.
shouldDisposeObjectMaterial(object)		Called when the default implementation of dispose() needs to free a Tile object's material.
shouldDisposeTexture(texture)		Called when the default implementation of dispose() needs to free a Texture that is part of a Tile object's material.
updateBoundingBox(newBoundingBox)	protected	Updates the tile's world bounding box.
willRender(_zoomLevel)		Called before MapView starts rendering this Tile.
