• 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:

v0.9.0

[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

v0.8.2

Changed

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

v0.8.1

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.

v0.8.0

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.
