I'm really looking forward to the next Pikmin now.

Re: A Generalized Ray Formulation for Wave-Optics Rendering
#12This is very neat, but I’m a bit surprised by their headline examples: > Materials admitting diffractive optical phenomena are visible: (a) a Bornite ore with a layer of copper oxide causing interference; (b) a Brazilian Rainbow Boa, whose scales are biological diffraction grated surfaces; and (c) a Chrysomelidae beetle, whose colour arises due to naturally-occurring multilayered interference reflectors in its elytro…
Yes, it's possible to do physically based diffraction grating effects in the traditional pipeline. Here's a tutorial on it: https://www.alanzucconi.com/2017/07/15/the-nature-of-light/ (I actually implemented this effect recently: the article is great overall, but you can get rid of the loop by using some simple algebra.)
However, as pointed out in sibling comments, this makes assumptions about the coherence of the light coming in.

#13Check out the others work from Benedikt Bitterli, it's very good
