FDCL released an open-source software library for harmonic analysis on SO(3). The FFTSO3 library supports parallel computation with OpenMP.

Fourier analysis on the rotation group provides computational tools for working with functions and probability densities over three-dimensional orientations. The original announcement links to the software repository.
