BB or anyone else, I need to understand the refaction node. I will give you three examples. Two are alike and one is not.

All have refraction..

I have a glass of water and I stick V4's finger in the water and the finger looks bent from light refraction. Both of your eyes see the entire surface of the water all at the same time or the water surface is small in size.

I have a swiming pool, and V4 is sitting on the edge of the pool, with her legs dangling in the water. The camera is pulled back to see the whole pool. Her legs look bent from the light refraction. Again both of your eyes see the entire surface of the water at the same time.

 

Now the question or issue

I have a small boat on a large body of water, think very large primitive disk, with a layer below the water, another large primitive disk with a sand texture. In real life if I was hovering over the boat, camera angle say at 65 degrees from horizontal, I would see the anchor line bend from refraction below the water line. The water is clear and I am able to see the bottom or sand below. But as I look in my perifery vision, I am looking through a thcker body of water and I can no longer see the bottom. The water color will become darker around the edges of my vision.  Poser scene, large body of water as explained above, with your (BB's) enviro sphere to create a sky-back-drop. There is a transmap on the water plane to provide a peek below the water surface. Edge=0 falloff=0. If I look to the edge of the disk where it meets the horizon, there appears to be banding or almost like a second layer under the water when the refraction is applied and it's not the bottom or sand layer. Somthing I didn't see in the glass of water or the swiming pool. Not sure if it is the pure size of the water disk. But it almost is like the refraction doesn't fade in the distance like you would expect in real life.

Should or does the refraction node act on a large surface inside Poser, like you would expect in real life??? Put another way does or should the refraction effect lower it's self the further you move away from the focal point of the camera.

It's almost like the transmap to let the camera see the bottom at the main focal point and the refraction are getting tangled up and it allows the camera to see below the surface of the water out at the perimeter of the water disk

1-Infinite light to act as the sun. Semi low rendering settings for testing.

I am not looking for somebody to build me a shader. I am trying to get a better understanding of exactly how refaction works in PoserPro 2012 around the edges of large surfaces.

TIA
