0.5.0 release

• A new function tokamesh.geometry.calculate_geometry_matrix has been added to replace BarycentricGeometryMatrix as the means of calculating geometry matrices.
• calculate_geometry_matrix supports parallelised calculation of geometry matrices via multiprocessing.
• Previously geometry matrix data was returned as a dictionary, but now calculate_geometry_matrix returns an instance of a new dataclass GeometryMatrix, which has methods for common operations on the data, such as production of sparse arrays and saving / loading.
• Functions which previously returned scipy.sparse matrix types by default now instead return sparse array types, as recommended for new code.
• TriangularMesh has a new method plot_field which can be used to efficiently generate color plots of fields represented by the mesh.

0.4.2 release

• Fixed an issue in BarycentricGeometryMatrix where mesh edges with a direction vector whose z-component is comparable to the float precision, but non-zero (i.e. almost exactly horizontal edges) could cause incorrect intersection calculations.

0.4.1 release

• The Triangle source code and the cython wrapper used to access it, which was previously bundled with tokamesh, has been removed in favor of using triangle PyPI package, which has been added as a project dependency.

0.4.0 release

• Increased minimum required Python version to 3.9.
• Moved all package metadata to the pyproject.toml and deleted the setup.cfg.
• Updated ReadTheDocs config files so they meet current requirements.
• Refactoring to improve module structure, resulting in new mesh and utilities modules.
• Improvements to type-hinting and documentation.

0.3.0 release

• @ZedThree has developed a Cython interface to the triangle.c code such that it can be used directly from Python, instead of communicating inputs / outputs via writing / read files to disk. Additionally, triangle.c is now compiled for various combinations of operating systems and Python versions when a Tokamesh version is published, such that it no longer needs to be compiled at runtime on a user's machine.
• Black has been applied to the entire code-base, and is now also automatically re-applied following commits / merges via GitHub actions.

0.2.0 release

• Added the find_triangle method to TriangularMesh to enable lookup of which triangles contain a given set of points.
• TriangularMesh and its methods now check the validity of their arguments.
• TriangularMesh.interpolate can now handle multi-dimensional numpy arrays as inputs.
