Changelog

[0.10.1] – 2025-05-08

Changed

  • The command medata_remove was renamed to metadata_extended_remove and can be used to remove the deprecated extended metadata from older files
  • Fixed the texture_update and texture_locate commands and also the save command with the --texture flag.
  • Fixed the conversion from .poly input when the file has comments or 1- index.
  • Fixed get_normal_newell(poly) to reject faces with > 3 points

Added

  • More tests and coverage
  • lint and format github action
  • --digit option for reprojections

Removed:

  • Support for extended metadata: specifically the commands metadata_create and metadata_update
  • All API functionality is deprecated: cjio.models and some functions from cjio.cityjson have been removed. Also all related tests.

[0.9.0] – 2023-09-28

Changed

  • now CityJSON v2.0 is the default version
  • fixes for gltf export
  • fix the cjio subset and children

Added

  • added an upgrade ops for v2.0 files

[0.8.2] – 2023-07-13

Changed

  • Removed the emojis in the console output for the function 'info'

[0.8.1] – 2023-02-06

Added

  • Added the translate paramter to cityjson.compress to manually set the tranlation properties instead of computing from the data.
  • The cityjson.cityjson_for_features and cityjson.generate_features methods.

Changed

gltf (glb) converter

  • to_glb sets a root transformation matrix for z-up to y-up, instead of swapping the vertex coordinates directly.
  • Takes a do_triangulate argument to completely skip triangulation.
  • Compute (smooth) normals.

[0.8.0] – 2022-11-28

Added

  • added functions for reading/writing CityJSONL (CityJSONFeatures) from stdin/stdout, so cjio can be part of a pipeline of operators processing 3D city models 🚀

Changed

  • many small bugs fixed
  • The function that used an API are going to be deprecated in the upcoming releases, because the cjio API is under refactoring. The affected functions are cityjson.save, cityjson.load, cityjson.save, cityjson.load_from_j, cityjson.get_cityobjects, cityjson.set_cityobjects, cityjson.to_dataframe, cityjson.reference_geometry, cityjson.add_to_j and all members of the cityjson.models module. There is a new cityjson library under development, called cjlib, which will replace the relevant parts in cjio.

[0.7.6] – 2022-09-12

Changed

  • cjvalpy >=v0.3 is required to use the latest schemas (v1.1.2)
  • fix the parsing of the validation string

[0.7.5] – 2022-08-08

Added

  • Subset more than one CityObject type (#9)
  • models.Geometry.reproject() for reprojecting dereferenced geometry boundaries
  • Read from stdin and save to stdout
  • --suppress_msg to suppress all messages. Required when saving to stdout

Fixed

  • Subset with BBOX does not modify the input model anymore (#10)
  • cityjson.load() does not fail on a GeometryInstance, however it does not load it either (#19)
  • Fixes to the glb exporter (#20, #57, #83), and fixed the coordinate system
  • texture and material are correctly removed from the geometries of the CityObjects with textures/materials_remove
  • vertex-texture is removed from the CityJSON with textures_remove
  • Docker image build (#77, #132)
  • Other minor fixes

Changed

  • Export format is an argument, not an option (#35), e.g. cjio ... export obj out.obj
  • NumPy is a hard requirement
  • Require pyproj >= 3.0.0 (#142)
  • Refactor warnings and alert printing (#143)

[0.7.4] - 2022-06-20

Fixed

  • crash with new version of Click (>=8.1) (#140)

Added

  • templates for bug reporting

[0.7.3] - 2021-12-15

Fixed

  • STL export (#127)

[0.7.2] - 2021-12-02

Fixed

  • String representation of the CityJSON class works again

[0.7.1] - 2021-12-01

Fixed

  • save operator was crashing for unknown reasons sometimes, this is fixed

[0.7.0] - 2021-12-01

Changed

  • Minimum required CityJSON version is 1.1
  • Many operators names changed, it's now "property-verb", so that all the operators related to textures for instance are together
  • The metadata are only updated (with lineage) when there is a metadata-extended property in the file, otherwise nothing is modified
  • The schema validator (operator validate) is not written in Python anymore and part of cjio, it's using cjval and its Python binding (which needs to be installed). The validator is several orders of magniture faster too

Added

  • A new operator triangulate that triangulates each surface of the input (de-triangulate coming soon)

Fixed

  • Several bugs were fixed

API

  • Loading a file with cityjson.load() removes the transform property from the file

[0.6.10] - 2021-10-18

Changed

  • Minimum required Python is 3.6

Fixed

  • Click option is set to None when empty (#99)
  • Loading breaks on inconsistent semantics (#102)
  • extract_lod doesn't work with the improved LoD (#80)

API changes

  • Added CityJSON.load_from_j
  • Make transformation the default on loading a cityjson
  • CityJSON.add_to_j includes reference_geometry, no need to call it separately

[0.6.9] - 2021-07-06

Changed

  • version with schemas 1.0.3 (where metadata schema is fixed)

Added

  • Convert to Binary glTF (glb)

  • Progress bar for the reproject command

  • Docker image and Travis build for it (#25)
  • Generate metadata (#56)
  • STL export format (#66)

Changed

  • click messages, warnings got their functions and placed into the utils module
  • only EPSG codes are supported for the CRS's URN
