hello guys. I'm trying to create a Snell's window effect http://en.wikipedia.org/wiki/Snell's_window
So it's clear that the Index of Reflection of surface water underwater won't equal Index of refraction of water (1,33), it just doesn't look like it. So the index of reflection for underwater should be reduced.
The angle of view of Snell's window is 96 degrees. How would it translate to index of reflection?
