> 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. https://en.wikipedia.org/wiki/Ambisonics#Higher-order_ambisonics https://en.wikipedia.org/wiki/Ambisonics#Higher-order_ambiso... https://en.wikipedia.org/wiki/Atomic_orbital#Orbitals_table https://en.wikipedia.org/wiki/Atomic_orbital#Orbitals_table ...and the same patterns appear on the unit disk with the Zernike polynomials, used to describe optical aberrations and more. https://en.wikipedia.org/wiki/Zernike_polynomials https://en.wikipedia.org/wiki/Zernike_polynomials

    I noticed that (similarity between the graphs and the shapes of atomic orbitals), and assumed that was what the article was about. And it wasn’t, and never brought it up, so I was thinking maybe I was confused about the similarity. So thank you for showing me I was not.

      lol, I was confused from the first imaging thinking this was going to be a tutorial on quantum physics then was confused even more as I scrolled

Ambisonics can give one end game audio

  end-game audio? Or it can give game audio to one end?

    A single Ambisonic B-format recording can be shipped and at runtime decoded into any coincident or near-coincident stereo pair pointing in any direction or into any surround sound format. It is a universal format that encodes the direction and intensity of arriving sound over a full sphere.
