orix is an open-source python library for analysing orientations and crystal symmetry.

The package defines objects and functions for the analysis of orientations represented as quaternions or 3D rotation vectors accounting for crystal symmetry. Functionality builds primarily on top of numpy and matplotlib and is heavily inspired by the MATLAB package MTEX.

If analysis using orix forms a part of published work please cite the associated preprint, which can be found here. You can also find demos in the orix-demos repo.

orix is released under the GPL v3 license.
