Pierre Massépierrotechnique@sonomu.clubApr 13, 2026, 4:55 AM@nicebyte wow, great work! absolutely comprehensive and yet looks straightforward enough for newcomers. you managed to convey quite a few of the strange little intuitions one needs to develop regarding the SH formalism

@pierrotechnique thank you!
Apr 13, 2026, 7:28 AM@nicebyte Great work! Is mesh thickness baking published anywhere? How would that work for meshes that don't form a one-to-one relation with a sphere?
Joni Korpijonikorpi@mastodon.gamedev.placeApr 13, 2026, 7:28 AM@nicebyte Thank you for writing this! More accessible for a non-expert like me than other sources.
Antonio Patriarcaantopatriarca@mathstodon.xyzApr 13, 2026, 7:51 AM@nicebyte Recently, I started looking more into physics and I think it is quite unfortunate that most sources are based on 3D and Physics as the spherical coordinate form is actually more difficult to understand then the Cartesian one in my opinion. It also takes one of the directions as the primary one (the z-direction in Physics). The Spherical Harmonics are simply the restriction on the sphere of harmonic homogeneous polynomials of a given degree. And even in physics, the Cartesian form is actually sometimes better for computations.
