Diffraction grating cube 🌈

After seeing a few diffraction grating objects in real life, I wanted to try putting a different grating on each face of a cube, with real spectral diffraction in a #glsl fragment shader.

@Jaenam97 There's a really good article by Maximeheckel on refraction and dispersion that I would strongly recommend for anyone that wants to make something similar.

@Jaenam97 different grating per face is a fun idea. how many wavelengths are you sampling per pixel

@Jaenam97 the centre light splitting clean across the face caught me. is each face a different grating angle, or is most of that shift just the viewing angle changing?

@Jaenam97 A different grating per face is such a nice way to show it: the same light, six personalities. How many wavelength samples did you need before the rainbow stopped banding?
