Yes it is quite thin, it would not be an enjoyable shower...
That's the way it is in the model already unfortuneately.  Perhaps I will
manually rework it or change the shower configuration altogether

Thank you for adding that. Reflection was solid 30-40 yards away,
at a low angle, in the outdoor pool image. For a high angle on a small body,
surface norms would do fine... if I understand this ...

did anyone mention
global_settings { number_of_waves Count }


#declare RippleNorm =
normal {
  average
  normal_map {
    [0.9 Bigripple]
    [0.8 Smallripple]
  }
}

3.5.11.35  Waves
When used as a normal pattern, this pattern uses a specialized normal
perturbation function. This means that the pattern cannot be used with
normal_map, slope_map or wave type modifiers in a normal statement.


OK now I'm just a little ichy ... grain of salt eh?

Not an issue for me anyways.  I convert to functions, and combine functions and
use a function pattern.  The main reason for this is beacuase I use it in a
heightfield rather than as a normal, but it should work either way.

Today I tried to find a suitable replacement for my Lego water:
 <web.49472c24399f7e1d778c150@news.povray.org>

I could not. I was able to make some watery chrome.

I'd love to see someone find something better than f_ridge for the Lego pool. I
doubt anyone can.

If you want to try, legoworld_pool.pov is in the legolib zip here:
http://home.earthlink.net/~openuniverse/


here's the norms you posted:

global_settings {
number_of_waves  1
RippleNorm 01
Bigripple 02
Smallripple 03
}

global_settings {
number_of_waves  2
RippleNorm 11
}

No. But that can also be used of course :-)

Whatever the docs say, it works for me anyway... :-)

Shower in mineral water... :-)

Those images look allright though... What code did you use here?

Well now that you mention it, I looked over what I grabbed for testing...

Really sloppy chrome, actually. I don't write stuff like this, but have been
know to paste it. Wont do that again.


all. The page had 6 lights, no radiosity used: this is water "11" in the 4-by
image, using the posted norms. (I dont think I changed them)

global_settings {
  number_of_waves  2
  assumed_gamma 1.9
  max_trace_level 5
}

camera {
  location <0, 50, -560>

light_source { <0, 8000, 0> color White
    spotlight
    point_at <0,0,0>
    radius 10
    falloff 90
}
light_source {<4000,-250,-4000> color Gray30
 fade_distance 8000 fade_power 2
}

light_source {<-5000, 2500, -5000> color Gray40
     fade_distance 8000 fade_power 2
}

light_source {

       normal { RippleNorm scale 5000 }
       finish { ambient 0 }
   }
   translate x*-18000

object { water5 }


thanks for posting code. One day we'll see a great picture for the effort.

I forgot the sky, of course.


#declare sky_blue =
sky_sphere {
    pigment {
        gradient y
        color_map {
         [0.0 rgb <0.6,0.7,1.0>]
          [0.7 rgb <0.0,0.1,0.8>]
        }
    }
}

sky_sphere { sky_blue }

The water probably doesn't look that bad.  The issue with water that makes it
interesting looking it what is available to reflect.  Your sky and background
is rather simple which ends up making the reflection very simple and chromey
looking.

I always point out that reflective surfaces only look as good as what is
available for them to reflect.
