Questions about the computations

[daidedou]

Hi,

Thank you for the amazing work!
I was wondering, just to be sure: you use spherical harmonics to handle some of your computations, right? I'm searching for a way to compute the spherical spectrum with torch bindings, and I thought that your library may already do the stuff.

Hi

Here I have an efficient implementation of spherical harmonics in pytorch https://docs.e3nn.org/en/latest/api/o3/o3_sh.html#e3nn.o3.cartesian_spherical_harmonics.spherical_harmonics

Hi,

Thanks for the fast answer! I looked a bit, but I'm not sure that this is what I want. I would like more a thing like https://shtools.oca.eu/shtools/public/ to compute the spherical spectrum directly. Maybe I'm asking too much, but since I've seen S2FFT somewhere, I thought it may be the same stuff (or maybe really similar!).
