September 18, 2022 CloudComPy release:

  • CloudComPy is now built with pybind11 instead of Boost.Python. For the CloudComPy user, the scripts are unchanged, but there is always the possibility of small changes in the behaviour of the code or bugs not covered by the tests. (if so, please post issues).
  • CloudComPy is built with Python 3.10 instead of Python 3.9, you have to use a new Conda environment (see the README for instructions).
  • update to CloudCompare master > 2.12.4 (september 15, 2022)
  • (issue #53) update pdal version to 2.4.2: needs conda Python 3.10. Works on Linux and Windows
  • (issue #54) fix the bug on save scalar fields with laz 1.4 -test added on extra scalar field saved an correctly loaded, see test020.py
  • (issue #64) a use case with invalid points (E57 file) and scalar fields to resize, see test041.py
  • (issue #65) add possibility of automatic downloading of sample files for ctest, update README for ctest, see test041.py
  • (issue #66) get access to global shift: see ccShiftedObject::getGlobalShift, see test006.py
  • Various small fixes.

** NOTE**: issues #49 and #50 are still under analysis, they will require further development. The changes done in the conda packaging and the use of pybind11 are a necessary step towards solving these issues.

** WARNING ** On Windows, with the binary based on the conda packages, Python 3.10, only the English version of CloudCompare is available, the translations are not available: it seems that this is due to a bug in the Qt 5.15.4 version of the conda package. We are waiting for the correction of this bug in the packaging.

  • Cross-section methods (issue #27). See test036.py
  • Extract Connected Components (issue #27). See test037.py
  • fix tests, activate trace on all tests to improve debug
  • add methods on primitives
  • fix a bug in conversion from C++ to Python, where objects name are missing.
  • fix keyword arguments problems when default value is nullptr
  • update README files, and add them in binary.

March 20, 2022 CloudComPy release:

  • Add access to plugin PCV (ShadeVis) on Windows and Linux (issue #24). See test032.py.
  • Add access to plugin HPR on Windows and Linux (issue#25). See test033.py.
  • Add access to plugin MeshBoolean on Windows and Linux. See test034.py.
  • The wrapping of the C2M and C2C algorithms has been rewritten. In some situations, the results were wrong (issue #26). Methods have been added or rewritten to facilitate parameterization that gives correct performance: ComputeApproxDistance methods with statistics, method for estimating the correct octree level. Automatic tests (test009.py, test010.py, test022.py) have been adapted. The performance tests (on Linux) shows no degradation between the GUI and CloudComPy.
  • Various improvements and bug fixes.

February 17, 2022 CloudComPy release:

  • Allow keyword arguments on methods with optional arguments, to avoid to fill a long list of default values (issue #20). See for instance test025.py in doc/PythonAPI/test025.py, where the methods have about 20 arguments with only two mandatory. The keyword arguments are not yet implemented on methods without optional arguments.
  • Debug traces from C++ are extended to messages from CloudCompare (the same we get on the CloudCompare GUI console). Need the environment variable CCTRACE=ON
  • Fix several problems related to las driver (issue #20):
    • On Linux, set the locale to C (same as default US locale) to avoid conversion problems from string to float.
    • The latest version of PDAL (2.3.0) is more restrictive on dimension names than 2.1.0.
  • Python package restructuration to handle properly the standard plugins: to get access to the wrapped methods of a plugin, this plugin must be explicitely imported: see for instance doc/PythonAPI/test030.py (plugin M3C2) the plugin M3C2 is the only standard plugin wrapped for the moment (issue #16).
  • Add some features to Rasterization (issue #21)
  • Various improvements and bug fixes.
