Visualization of matrix Fisher distribution
We implement the visualization via color coding on a 2-sphere. This method was proposed in [1] and first used in [2]. However, we did not find the released code on this visualization.
This implementation was used in [3] (Project page). Please consider citing [3] if you find this implementation helpful.
This implementation may not be perfect. Feel free to raise issues if you have better ideas.
