Changelog¤

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased¤

Added¤

  • Declared runtime dependencies in pyproject.toml: numpy>=1.24 and compas>=2.15,<3 (previously undeclared, leaving installs to fail at import time on clean environments).
  • Added docs/examples/example_measure.md documenting mesh_area, mesh_volume, and mesh_centroid so the measure example renders alongside the others.
  • Added image reference in docs/examples/example_isolines.md and added Measure: examples/example_measure.md to the Examples nav in mkdocs.yml.
  • Added docs/examples/example_booleans_with_edges.md and example_booleans_with_face_source.md (with their images) covering the corefinement intersection-edge and face-source-tracking variants of the boolean operations; both wired into the Examples nav.
  • Added docs/examples/example_boolean_difference_mesh_meshes.md (CSG drilled rounded cube) and its Examples nav entry.

Fixed¤

  • Fixed docs/examples/example_projection.py imports: project_mesh_on_mesh, project_points_on_mesh, pull_mesh_on_mesh, and pull_points_on_mesh were incorrectly imported from compas_cgal.meshing instead of compas_cgal.projection, causing ImportError for anyone running the example.

Changed¤

  • Bumped nanobind build-system requirement from >=1.3.2 to >=2.12 to fix refined_delaunay_mesh (and other Eigen::Ref overloads) raising TypeError: incompatible function arguments when called with numpy>=2.4.0.
  • Extended [tool.cibuildwheel] test-requires to numpy>=2.4 and compas>=2.15,<3 so the wheel test job exercises the post-2.4 ndarray ABI on every build.
  • Applied ruff format to docs/examples/example_booleans_with_face_source.py, docs/examples/example_isolines.py, tasks.py, and tests/test_booleans.py so the working tree is clean for the next invoke release run.

Changed¤

  • Added optional surface meshing parameters (sm_angle, sm_radius, sm_distance) to compas_cgal.reconstruction.poisson_surface_reconstruction for controlling mesh quality and density.

  • Upgraded cibuildwheel manylinux image from manylinux2014 to manylinux_2_28 for scipy wheel compatibility.
