Changelog#

0.3.0 (upcoming)#

pxios command line interface with fetch, list, convert and viz subcommands. Visualization requires the optional viz extra (pip install polyxios[viz]).
polyxios.read_polydata and polyxios.visualize_mesh helpers, plus polyxios.supported_extensions to introspect the codec registry.

The fetcher now resolves assets through a remote models.json catalog and downloads files individually, instead of pinned per-format release zips. Downloads are checksum-verified and the result is cached across runs; set POLYXIOS_MODELS_URL to pin the catalog to an immutable URL.

First public release of polyxios.

Plugin-based codec registry via Python entry points — third-party packages can register mesh formats without patching polyxios.
VTK legacy (.vtk) and XML (.vtu, .vtp) reader/writer with ASCII and binary (raw + appended) encoding.
VTR appended format support.
MFEM mesh codec (.mesh).
MEDIT mesh codec (.mesh).
polyxios convert and polyxios visualize-mesh CLI commands.
Lazy / memory-mapped loading for binary formats (read(..., lazy=True)).
polyxios.__version__ exposes the full version string including the git commit hash for development builds (e.g. 0.1.0.dev0+git20260623.101006a).
