API Reference > core-frontend > Tiles > GeometryTileTreeReference > collectTileGeometry collectTileGeometry Method Populate TileGeometryCollector.polyfaces with geometry satisfying collector's criteria. Because tile geometry is obtained asynchronously, successive collections over multiple frames may be required before the list of polyfaces is fully populated. collectTileGeometry(collector: TileGeometryCollector): void see TileGeometryCollector.isAllGeometryLoaded to determine if the list of polyfaces is fully populated. Parameter Type Description collector TileGeometryCollector Returns - void Defined in core/frontend/src/tile/TileGeometryCollector.ts Line 116 Last Updated: 02 February, 2022
