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 NumPy and Matplotlib and is heavily inspired by the MATLAB package MTEX.

orix is released under the GPL v3 license.

Refer to the documentation for detailed installation instructions, a user guide, and the changelog.

orix can be installed with pip:

pip install orix

or conda:

conda install orix -c conda-forge

You can also visit PyPI, Anaconda or GitHub to download the source.

Further details are available in the installation guide.
