py3dtiles.tilers.b3dm.wkb_utils module

class py3dtiles.tilers.b3dm.wkb_utils.TriangleSoup[source]

Bases: object

static from_wkb_multipolygon(wkb: bytes, associated_data: list[bytes] | None = None) → TriangleSoup[source]
Parameters:

  • wkb – Well-Known Binary binary string describing a multipolygon

  • associated_data – array of multipolygons containing data attached to the wkb parameter multipolygon. Must be the same size as wkb.

get_bbox() → list[ndarray[Any, dtype[float32]]][source]

Returns the bbox in this format: [[minX, minY, minZ],[maxX, maxY, maxZ]]

get_data_array(index: int) → bytes[source]

Returns a binary array of vertex data

get_normal_array() → bytes[source]

Returns a binary array of vertex normals

get_position_array() → bytes[source]

Returns a binary array of vertex positions
