Entering two rounds in sequence?  You must have a lot of spare time...

I think media would be a better solution anyway, with scattering you could
even show the shadows of the trees...

I think it looks fairly good already, i don't look at water surfaces from
below very often so i'm not completely sure... ;-)  In contrast to water
from above you have the effect of total reflection at shallow angle.

Maybe try raising the minimum reflection to just a bit above 0.  In
addition i suppose media could also have a good effect on this too.

Not so much as I want, but I know, what you mean.
And you? - two entries in one single year; some people might think you are
exaggerating.

Are you trying to say i'm unproductive? ;-)

Sometimes it's simply more appealing not to have a fixed topic and a
deadline, at least this is more cooperative to real life obligations...

Well, maybe you should add some trees behind.  I think some shadowing
would improve it although radiosity would be quite mandatory then.

I would never risk such an assertion!   though...  ;-)

Are you actually aware about having set up the record for the longest render
time (ca. 12 days)
of all IRTC entries?
Although Gena Obukhov with 83 h on 15 Dec Alphas
(http://www.irtc.org/ftp/pub/stills/2000-08-31/gosea.jpg) and Claudio
'Naxos' Gallego with 235 h on a 4 processor machine
(http://oz.irtc.org/ftp/pub/stills/1997-02-28/bar.jpg) perhaps beat you in
terms of Tflops per entry ;-)

Nothimg is ready. Plants, trees, heightfield and water are only provisional
to get a quick impression.

No, i wasn't aware, are you sure you did not miss anything longer?

I sadly lost the render stats for it because i piped another render
afterwards and it crashed.

Chicken..." were 14 days
(
http://www.povray.org/preview/irtc-cd3/stills/19981231/view/ac_vs_eb.htm ).
Sorry

Anyway, more important than the render stats is the image itself. And
ShangriLa is truly amazing.
