orix#

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

The package defines objects and functions for the analysis of orientations accounting for crystal symmetry. Functionality builds primarily on NumPy and Matplotlib, and is heavily inspired by the MATLAB package MTEX.

Installation#

orix can be installed with pip or conda:

pip install orix
conda install orix -c conda-forge

Further details are available in the installation guide.
