py3dtiles package

class py3dtiles.B3dm

Bases: TileContent

static from_array(array)

Parameters

array : numpy.array

Returns

t : TileContent

static from_glTF(gltf, bt=None)

Parameters

gltfGlTF

glTF object representing a set of objects

btBatch Table (optional)

BatchTable object containing per-feature metadata

Returns

tile : TileContent

class py3dtiles.BatchTable

Bases: object

Only the JSON header has been implemented for now. According to the batch table documentation, the binary body is useful for storing long arrays of data (better performances)

Parameters

positions_dtype : numpy.dtype

positionsnumpy.array

Array of uint8.

colors_dtype : numpy.dtype

colorsnumpy.array

Array of uint8.

Returns

f : Feature

static from_values(x, y, z, red=None, green=None, blue=None)

to_array()

class py3dtiles.GlTF

Bases: object

static from_array(array)

Parameters

array : numpy.array

Returns

glTF : GlTf
