Fast and exact Wigner Transforms

SO3: Fast Wigner transforms

DESCRIPTION

The SO3 code provides functionality to perform fast and exact Wigner transforms based on the sampling theorem on the rotation group derived in McEwen et al. (2015).

INSTALLATION

The python package, so3 (pyso3 was taken), is available on so3 and can be installed with:

pip install so3

The C package can be installed with CMake and conan:

Both can be installed using pip:

pip install conan cmake

Then SO3 can be compiled with:

git clone http://astro-informatics.github.io/so3/ -b main
mkdir so3/build && cd so3/build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local -Dconan_deps=True ..
make
make install

The above will also download FFTW and SSHT and compile them, if necessary.

DOCUMENTATION

Further documentation is available here.

Usage for the python package is also given in the package docstring.
