py3dtiles.tileset.content.pnts module

class py3dtiles.tileset.content.pnts.Pnts(header: PntsHeader, body: PntsBody)

Bases: TileContent

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

Creates a Pnts from an array

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

Creates a Pnts from features defined by pd_type and cd_type.

static from_file(tile_path: Path) → Pnts

static from_points(points: Points) → Pnts

Create a pnts from data array:

• positions will be included as SemanticPoint.POSITION

• if rgb is not None, it will be included as SemanticPoint.RGB

• all the extra_fields are included in the batch table

Parameters:

• positions – the positions 1D array

• colors – the colors 1D array

• extra_fields – a dict of extra arrays to include in the batch_table. The dict keys are the name of the fields, the values are 1D np arrays containing values for each field.

sync() → None

Synchronizes headers with the Pnts body.

class py3dtiles.tileset.content.pnts.PntsBody

Bases: TileContentBody

static from_array(header: PntsHeader, array: ndarray[Any, dtype[uint8]]) → PntsBody

Creates a PntsBody from an array and the header

get_points(transform: ndarray[Any, dtype[float64]] | None) → Points

to_array() → ndarray[Any, dtype[uint8]]

Returns the body as a numpy array.

class py3dtiles.tileset.content.pnts.PntsHeader

Bases: TileContentHeader

BYTE_LENGTH = 28

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

Create a PntsHeader from an array

magic_value: Literal[b'b3dm', b'pnts']

to_array() → ndarray[Any, dtype[uint8]]

Returns the header as a numpy array.
