Class VectorTileset

constructor

• new VectorTileset(
      source: VectorTileSource,
      frame: GeoFrame,
      device: GPUDevice,
      cache: TileCache<VectorTileContent>,
      groundHeight?: (lonRad: number, latRad: number) => number | null,
      hasTerrain?: () => boolean,
      style?: VectorStyle,
      debug?: VectorDebugOptions,
      wallInsetMeters?: number,
  ): VectorTileset

  Parameters

  • source: VectorTileSource
  • frame: GeoFrame
  • device: GPUDevice
  • cache: TileCache<VectorTileContent>
  • groundHeight: (lonRad: number, latRad: number) => number | null = ...

    Terrain ground-height lookup so buildings/roads/landuse sit on the ground. Default: ellipsoid (0).

  • hasTerrain: () => boolean = ...

    Whether the scene has any terrain. When true, a tile defers its build until terrain is loaded under it (so it bakes at the real ground height, not floating/sinking); when false there's no terrain to wait for, so it builds immediately at the ellipsoid.

  • style: VectorStyle = DEFAULT_VECTOR_STYLE

    Which source-layers become fill / line / extrusion geometry, and their colors / widths / heights — from a MapLibre style (parseMapLibreStyle) or the built-in default.

  • debug: VectorDebugOptions = {}

    Debug isolation (off in normal use) — see VectorDebugOptions.

  • wallInsetMeters: number = DEFAULT_WALL_INSET_METERS

    Metric footprint inset that de-fights shared party walls; 0 = off. See DEFAULT_WALL_INSET_METERS.

  Returns VectorTileset

maxSSE

attributions

• get attributions(): Attribution[]

  Returns Attribution[]

buildsPerFrame

• get buildsPerFrame(): number

  Max tile GPU uploads applied per frame (default BUILDS_PER_FRAME). Raise for faster fill-in at the cost of bigger frame hitches; lower for smoother movement.

  Returns number

• set buildsPerFrame(n: number): void

  Parameters

  • n: number

  Returns void

init

• init(): Promise<void>

  Returns Promise<void>

update

• update(p: SelectParams): VectorTileContent[]

  Parameters

  • p: SelectParams

  Returns VectorTileContent[]
