Class GeoDecalOverlay

constructor

• new GeoDecalOverlay(
      frame: GeoFrame,
      texture: GPUTexture,
      centerLonLat: DecalLonLat,
      extentMeters: number,
      opts?: GeoDecalOptions,
  ): GeoDecalOverlay

  Parameters

  • frame: GeoFrame
  • texture: GPUTexture

    The decal image (top-down; transparent outside the overlay). Sampled by the projector; typically from rasterizeVectorDecal.

  • centerLonLat: DecalLonLat

    Footprint center (degrees).

  • extentMeters: number

    Side length of the square footprint the projector covers (m). Match the texture's coverage — see rasterizeVectorDecal's result.

  • opts: GeoDecalOptions = {}

  Returns GeoDecalOverlay
