PyCityJSON

Python CityJSON io, editor and modeling library

Loading a file :

import pycityjson.io as cjio
import pycityjson.model as cj

city = cjio.read('railway.city.json')

Selecting an object :

# SolitaryVegetationObject with GeometryInstance
uuid = 'GMLID_SO0286258_965_2893'
cityobject = city[uuid]

Applying a transformation on an object :

matrix = cj.TransformationMatrix().translate((0, 0, 12))
cityobject.transform(matrix)

Saving the modified CityJSON file :

cjio.write_as_cityjson(city, 'railway_modified.city.json', pretty=False, purge_vertices=True)

Saving the modified CityJSON to wavefront :

cjio.write_as_wavefront(city, 'railway_modified.obj', as_one_geometry=False, swap_yz=True)
