Changelog

[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)
fix bugs with operators update_metadata_cmd() and get_metadata_cmd() crashing

Changed

fix bug: crash when validating files containing Extensions under Windows

[0.6.0] - 2020-10-27

Added

Convert to Binary glTF (glb)
Convert to Batched 3D Models (b3dm) - Output is probably incorrect though
Progress bar for the reproject command
Started a proof of concept for an API. You can read about the first struggles in docs/design_document.ipynb. Mainly implemented in models and a few additional methods in cityjson. Plus a bunch of tests for the API (#13)
Add tutorials and dedicated documentation
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
When --indent is passed to save, tabs are used instead of spaces. Results in smaller files.
