class py3dtiles.tileset.content.Pnts(header: PntsHeader, body: PntsBody)[source]

Bases: TileContent

static from_array(array: ndarray[Any, dtype[uint8]]) → Pnts[source]

Creates a Pnts from an array

static from_features(feature_table_header: PntsFeatureTableHeader, position_array: ndarray[Any, dtype[float32 | uint8]], color_array: ndarray[Any, dtype[uint8 | uint16]] | None = None, normal_position: ndarray[Any, dtype[float32 | uint8]] | None = None) → Pnts[source]

static from_file(tile_path: Path) → Pnts[source]
static from_points(points: ndarray[Any, dtype[uint8]], include_rgb: bool, include_classification: bool) → Pnts[source]
Create a pnts from an uint8 data array containing:

  • points as SemanticPoint.POSITION

  • if include_rgb, rgb as SemanticPoint.RGB

  • if include_classification, classification as a single np.uint8 value that will put in the batch table
