reflection is when light bounces back at the exact opposite angle that it
reaches the object. Refraction is when light bounces back at different
angles. A prism would be a good example of refraction.

Refraction is very hard to replicate in a program. It requires a lot of
thinking and stuff so that is basically out of the question.

Now, it would be a good idea to set a seperate fog level for under water. I
am relatively positive that in perfect circumstances, you can see just as
far in water as above water. Because of pollution and such, I'm sure you
could see much further under water than above if the water was perfectly
pure.

It would be a good idea if you could use a seperate fog control under the
water because, as Bowen said, there is a lot of sand and dust and things
that are often floating around in the water. Because of that, the "fog" (it
really isn't like the fog that is above the water) can limit you to only a
few feet of clear visibility in the ocean near the shore. However, it calms
down as you move further from where the waves break and is much clearer.
Perhaps a diffent type of fog could be set so that the fog slowly becomes
clearer as you move away from the shore.
