This is my first serious test with water and photons. I tried a very
clear pool water, using some RL photos as reference.


P.S.: source on p.b.s-f.

I've got no idea how deep the water is. 

Earlier in the year Chris Huff did some exelent examples of water
in buckets, using photons.  The photons seem to wash out a bit
in your scene.

Whoa...that looks pretty nice!  However, I'll have to agree with Steve; I
really can't tell how deep the pool is :-)

Also, the beach ball looks to be levitating, but that's not really important
:-)

I don't think you ought to be able to see how deep the
water is, unless you did a stereoscopic render. I know
that I will sometimes render a scene over and over
because I mistakenly expect something that ought not
be there. My expectations are sometimes not as realistic as
POV-Ray ;-(

Interestingly, even with a stereoscopic render, you still wouldn't be able
to tell very well because the refraction would trick you, just like it does
in real life - it'd look shallower than it would without refraction.

Neat =)

  Yes, it's difficult to tell the depth, but as Harold, I think this
happens also on reality. Perhaps it is a bit exaggerated due to the fact
that photons *are* whasing out the pool floor.  I thinks this is due to
the excess of light and also because I must use a slighty higher count.
