> spherical harmonics can have uses beyond lighting

This math is also used in Ambisonic surround sound though newer techniques use planewave expansion.

For games, the full-sphere encoding of Ambisonic B-format can be decoded for arbitrary speaker locations and the soundfield rotated around any axis. I'm not sure if its ever been used for a game though.

... also quantum mechanics. The textbook solution for the wavefunction of the hydrogen atom involves spherical harmonics.

That fact is betrayed by the the similarity of the shapes of atomic orbitals and the sensitivity patterns of Abisonic B-format channels.

...and the same patterns appear on the unit disk with the Zernike polynomials, used to describe optical aberrations and more.

Ambisonics can give one end game audio

end-game audio?

Or it can give game audio to one end?
