Creating visual representation of spherical harmonics

I want to create a 3D visual representation of real spherical harmonics. I just don’t know where to start. I’m aiming for polar plots with magnitude as radius, or amplitude as elevation, as described on the Wikipedia Table of spherical harmonics.

Has anyone here tried this before?

Can it be done in UE alone, or is fancier software needed?

How could it be achieved?

I’ll go out on a limb here, and say that the first representation look like a Fibonacci lattice?

If that’s so, you could use that and world position offset ( on a sphere with a lot of polys ).

I don’t think this is the case, and it also wouldn’t describe the representations of the first order, when m = 0.

Ah, my bad…
