I’m having a hard time understanding what the fresnel parameter does when it comes to raytraced mirrors.
I know what a fresnel lense is (thats mostly the only information I can find on it), but how does this apply to reflections? Can someone reference a real world object in which fresnel is apparent?
try this sometime you’re at a puddle [or pool of water]
stand off beside it looking at the reflections at a glancing angle
then walk and look directly down on it at your reflection
you will be able to see the reflection a lot easier at a glancing angle than when looking straight down on the water, this is the fresnel effect and the fresnel paramater can alter how that effect works.
