Hi again:

  Thanks to all for the comments on the prior wip. Sorry, but as the
lazy I am, I've been delaying the replies untill I had ready the next
wip... ;)

  I've used a real model for the streams, but the problem might be that
the pipes are not very visible and must be lower respect to the water
levels. Thanks for the tip about the leaves: I've reduced the phong now.
I also reduced the grain on the isosurface floor tiles.

  Well, I forgot to mention that I used a two-pass method for rad, with
simpler geometry and textures for the saving step. Anyhow, it is slow on
some of the isos with more complicated formulas.

  I also changed the white balance, you were right about it being too
neutral. The noise on the isosurfaces is now a custom pigment, wich
gives better results getting ride of regularity. Better now?

  That would be a "horchata", as this patio is very Valencian. :)

  Yeah, they were too simplistic: I've worked that a bit.

  Done! :)

  I'm trying to find a good balance, but it is a specially difficult
scene, and could vary highly from monitor to monitor...

Jim Charter:
> I can't believe you wrote a function to make the shape of arches!

  Neither me, but I started with the tutorial on the docs, and casually
one of the examples only needed an inversion to resemble somthing like
an arch. From here I started to tweak the shape by trial and error.
Later I added some noise with pigments, and lerned with Mike tutorial to
"join" shapes for the columns. Hard but really funny!

  Very nice fountain! Thanks for the tip. I was already making it with
a sort of "boiling water", although it's not very visible.


  Thanks again for all the suggestions. I will post the final image next
time, with some details enhanced (and the posible comments to this one,
of course!).

  Regards..
