Methods

Name Description
adjustHeights(minHeight: number, maxHeight: number): void Adjust the minimum and maximum elevations of the terrain within this tile.  
getProjection(heightRange?: Range1d): MapTileProjection Obtain a MapTileProjection to project positions within this tile's area into 3d space.  

Inherited methods

Name Inherited from Description
computeVisibility(args: TileDrawArgs): TileVisibility RealityTile Determine the visibility of this tile according to the specified args.
countDescendants(): number RealityTile Primarily for debugging purposes, compute the number of tiles below this one in the TileTree.
dispose(): void RealityTile Dispose of resources held by this tile and all of its children, marking it and all of its children as "abandoned".
disposeChildren(): void Protected RealityTile Dispose of this tile's child tiles and mark them as "not loaded".
drawGraphics(args: TileDrawArgs): void RealityTile Output this tile's graphics.
isFrustumCulled(box: Frustum, args: TileDrawArgs, testClipIntersection: boolean, sphere?: BoundingSphere): boolean Protected RealityTile  
loadChildren(): TileTreeLoadStatus Protected RealityTile If this tile's child tiles have not yet been requested, enqueue an asynchronous request to load them.
meetsScreenSpaceError(args: TileDrawArgs): boolean Protected RealityTile Returns true if this tile is of at least high enough resolution to be displayed, per the supplied TileDrawArgs; or false if
setGraphic(graphic: undefined | RenderGraphic): void Protected RealityTile  
setIsReady(): void RealityTile  
setLeaf(): void RealityTile  

Properties

Name Type Description
mapTree Readonly MapTileTree The MapTileTree to which this tile belongs.

Inherited properties

Name Type Inherited from Description
_childrenLoadStatus Protected TileTreeLoadStatus RealityTile The current loading state of this tile's children.
_contentId Protected string RealityTile Uniquely identifies this tile's content in the context of its tree.
_contentRange Protected undefined | Range3d RealityTile A volume no larger than this tile's range, and optionally more tightly encompassing its contents, used for more accurate culling.
_graphic Protected undefined | RenderGraphic RealityTile This tile's renderable content.
_hadGraphics Protected boolean RealityTile True if this tile ever had graphics loaded.
_maximumSize Protected number RealityTile The maximum size in pixels this tile can be drawn.
boundingSphere Readonly BoundingSphere RealityTile The bounding sphere for this tile.
bytesUsed number RealityTile Exclusively for use by LRUTileList.
center Accessor ReadOnly Point3d RealityTile The point at the center of this tile's volume.
children Accessor ReadOnly undefined | Tile[] RealityTile This tile's child tiles, if they exist and are loaded. The children are fully contained within this tile's volume and provide higher-resolution graphics than this tile.
contentId Accessor ReadOnly string RealityTile Uniquely identifies this tile's content.
contentRange Accessor ReadOnly Range3d RealityTile A volume no larger than this tile's range, and optionally more tightly encompassing its contents, used for more accurate culling.
depth Readonly number RealityTile The depth of this tile within its TileTree.
hasContentRange Accessor ReadOnly boolean RealityTile True if this tile has a known volume tightly encompassing its graphics.
iModel Accessor ReadOnly IModelConnection RealityTile The IModelConnection to which this tile belongs.
isLeaf Accessor ReadOnly boolean RealityTile True if this tile has no child tiles.
isLoading Accessor ReadOnly boolean RealityTile True if this tile's content is currently being loaded.
isNotFound Accessor ReadOnly boolean RealityTile True if an attempt to load this tile's content failed.
isQueued Accessor ReadOnly boolean RealityTile True if a request for this tile's content has been enqueued.
loadStatus Accessor ReadOnly TileLoadStatus RealityTile Tile contents are loaded asynchronously on demand. This member tracks the current loading status of this tile's contents.
maximumSize Accessor ReadOnly number RealityTile The maximum size in pixels this tile can be drawn. If the size of the tile on screen exceeds this maximum, a higher-resolution tile should be drawn in its place.
next undefined | RealityTile Exclusively for use by LRUTileList.
parent Readonly undefined | Tile RealityTile The parent of this tile, or undefined if it is the TileTree's root tile.
previous undefined | RealityTile Exclusively for use by LRUTileList.
radius Accessor ReadOnly number RealityTile The radius of a sphere fully encompassing this tile's volume - used for culling.
range Readonly Range3d RealityTile The volume of space occupied by this tile.
tileUserIds undefined | RealityTile Exclusively for use by LRUTileList.
tree Readonly TileTree RealityTile The TileTree to which this tile belongs.
usageMarker Readonly TileUsageMarker RealityTile Tracks the usage of this tile.
