Releases | Open Source Science

Added

support for CityJSON Lines (CityJSONL) files, the 1st line of the file must be with the "transform", best is to use cjio output
support for 3D types of JSON-FG, only the Polyhedron and MultiPolyhedron (not for Prism and MultiPrism) (JSON-FG is still beta, so I guess this might have to change)
added a simple Python-based viewer to visualise the errors, see /tools/viz3dity/ for more details
API now supports OBJ and OFF; all formats supported by val3dity actually ### Changed
the API is new and simpler, only 2 functions are now used: is_valid() + validate()
error 609 has been renamed 906 (no geometry is for more formats than only CityJSON)
simplified the code for CDT of each surface (faster too)
upgraded to latest version of pugixml, to parse XML files

Changed

the structure of the report was fixed (it is more flat, as it should have always been), it made little sense for Composite/Multi/Solid
geometry IDs in the report are 0-based (as they should, a bug made them start at 1, now fixed)
compilation under Windows to get a binary is now automised with GitHub Actions

Added

val3dity can now be compiled as a library and easily used in other C++ binary (it's GPLv3 license, watch out)
this allows val3dity to be used with Python now, see https://github.com/tudelft3d/val3ditypy/
unit test for IndoorGML files
support for the simple format tu3djson (https://github.com/tudelft3d/tu3djson) ### Changed
fixed a few bugs for the parsing of IndoorGML files
LoDs of Buildings are now taken into account when validating the topological relationships between BuildingParts: the tests are now per LoD now (so no "clash" between LoD1.3 and LoD2.2 if stored in the same file) ### Removed
removed the support for CityGML files and 'vanilla' GML files. Only IndoorGML files can be read, and support for GML 3.3 is not fully there yet. Most errors/issues that are reported with val3dity have to do with a faulty parser of CityGML, and not with val3dity itself. I cannot justify spending 100s of hours fixing the parser, I tried hard but this not possible anymore. If someone wants to do it then great I am willing to help them, but I will not invest time on this anymore. Just upgrade your files to CityJSON (https://www.cityjson.org/tutorials/conversion/), I'll always maintain a full CityJSON parser!

Added

support for IndoorGML datasets, not just the geometries but specific validation tests for the primal-dual consistency were added
support for GeometryTemplates in CityJSON (https://www.cityjson.org/specs/#geometry-templates)

Changed

completely revamped the JSON error report, it's better and clearer
no more HTML output for the report (output of report is now with option --report, be careful), but you can just drag your JSON report to the HTML page (in folder /report_browser/index.html) or at http://geovalidation.bk.tudelft.nl/val3dity/browser/
improved the error codes a bit: new errors for IndoorGML (7xx) + for handy faulty inputs (error 904)
code must now be compiled against CGAL5, easier to install and compile for everyone
CityGML support is deprecated. This is the last version that will support CityGML, I will remove it completely from v2.3+. Most errors/issues reported have to do with a faulty parser of CityGML, and not with val3dity itself. I cannot justify spending 100s of hours fixing the parser, I tried hard but this not possible anymore. If someone wants to do it then great I am willing to help them, but I will not invest time on this anymore. Just upgrade your files to CityJSON (https://www.cityjson.org/help/users/conversion/), I'll always maintain a full CityJSON parser!

val3dity - val3dity release version 2.1.1 Windows binaries

This is an automated val3dity release

- C++
Published by hugoledoux over 6 years ago

[2.1.1] - 2019-04-30

Changed

several small bug fixes: wrong handling of some GML namespaces is one of them
tol_snap can't be disabled anymore: just too error-prone and means nothing. Give a super small value instead, like 1e-12

val3dity - 2.1.0: new report to allow val3dity to support more data models

The core validation stayed exactly the same, no changes. Only these were modified: - the report is slightly changed: the CityObjects/Primitives subdivision in the report is replaced by Features having Primitives, where Features are the top-level objects, containing one or many Primitives. This is done to allow other data model to be used as input, eg IndoorGML is coming soon! - pytest allows to specify the binary to use if not under 'build/'
