  • pysfcgal.sfcgal.mapping
  • pysfcgal.sfcgal.point_to_coordinates
  • pysfcgal.sfcgal.linestring_to_coordinates
  • pysfcgal.sfcgal.polygon_to_coordinates
  • pysfcgal.sfcgal.multipoint_to_coordinates
  • pysfcgal.sfcgal.multilinestring_to_coordinates
  • pysfcgal.sfcgal.multipolygon_to_coordinates
  • pysfcgal.sfcgal.geometrycollection_to_coordinates
  • pysfcgal.sfcgal.triangle_to_coordinates
  • pysfcgal.sfcgal.tin_to_coordinates
  • pysfcgal.sfcgal.polyhedralsurface_to_coordinates
  • pysfcgal.sfcgal.solid_to_coordinates
  • pysfcgal.sfcgal.triangle_to_polygon
  • pysfcgal.sfcgal.tin_to_multipolygon
  • pysfcgal.sfcgal.solid_to_polyhedralsurface

Feat

  • Polyhedralsurface.to_solid()
  • update sfcgal_def_msvc
  • update C API after recent changes in SFCGAL
  • 2D- and 3D-translations
  • convert the IO functions as new Geometry class methods
  • scale operations
  • write geometries as VTK/OBJ files/strings
  • implement rotation operations
  • buffer 3D on Point and LineString
  • straight skeleton partition
  • support MultiSolid

Fix

  • add C files to package_data
  • fix the Python image name in the CI jobs
  • do not directly invoke setup.py to build windows package
  • Geometry.extrude() returns a Solid instead of a PolyhedralSurface
  • fix vtk functions
  • fix memory issue by using lib.sfcgal_geometry_clone
  • test: Fix WKT in tests after https://gitlab.com/sfcgal/SFCGAL/-/merge_requests/361
  • icontract decorators must have a lambda as the first parameter
  • call the same decorator several times

Refactor

  • split test on geometries, a module per geometry type
  • build geometries from coordinates and geojson-like data
  • geom-to-coordinates converters as geometry class methods
  • wrap_geom becomes a method of the Geometry class
  • geom1_to_geom2 converters considered as geometry class methods
