09 Dec 2013 Generate Non-Parallel Axes Generate n 'well-spaced' axes -- uniform sampling of 3D rotation axes Author: Aaron Becker

Yes Anton, uniform-sampling-of-a-sphere is great software, and I've acknowledged its inspiration! However, sampling rotation axes is fundamentally different because Euclidean vectors r and -r are on the same axis.
In the uniform sphere sampling problem with n=2 the solution is any antipodal points, but for uniform axes sampling the solution is two orthogonal axes. Similarly for sphere sampling with n=3 the solution is three equidistant points on a great circle, but for axes sampling the solution is 3 orthogonal axes.
I needed software to generate rotation axes that were as far from being parallel as possible.

Here is another function on FEX that does the same thing and more:
