An example of iridescence shader extending the Lit shader in Unity URP.
Single-layered thin-film BRDF by Laurent Belcour and Pascal Barla's paper.
- Single-layered thin-film (Soap bubble)
- Multi-layered thin-film
- Diffraction grating (CD-ROM)
- Biological iridescence (Morpho butterfly wing scales)
I'll need to further study the underlying principle of these iridescences and find a way to modeling them that suitable for real-time rendering.
