Iβve started to use yafray and there are many terms that I still find confusing and I was wondering if there is a website about the physics of light, you know like photons, refraction, etc. Thanks.
You could try this one:

But be careful: you may end up more confused than before! Many of the terms used in CG rendering donβt necessarily match 100% to the physics.
Cool websites, great, thanks a lot!!!
