Hello everyone.
A lot of research went into this part of the Diamond Series. In this nerdy episode we will be diving deep into dispersion and learn about Cauchy, Abbe and other interesting stuff around physical values to recreate all refractive materials in 3D.
Thank you very much for watching.
P.s. leave a comment if you have any good Idea for a future quick tip / tut.
