The file size is huge for what you've posted, it's a basic work in
progress and you could have got away with a much smaller file in KB
without losing any quality.
It's looking good so far.

Christoph has at least 2 different pages dealing with water, and based on
your image I think you refer to the toturial about setting up the
reflections, media, and to a lesser degree, the ripples... But the page I
had in mind, offers a quite complicated macro for you to download, that
simulates the behaviour of water surfaces in motion (a simplified behaviour
but better than I've seen elsewhere in POV).. Here's the link, in any case:
http://www-public.tu-bs.de:8080/~y0013390/pov/water/water_inc.html
By default it generates isosurfaces but for speed reasons, heightfields are
the better choice and it's not hard to setup to output a heightfield.. Well
the pattern will then repeat itself because you will probably copy the
heightfield to several places in the scene to fill an ocean...
But it's worth a look, if you missed it. ;o)

Hugo

Try rendering an orthographic top down view with no lights, ambient 1 gradient y
pattern at large size (depth_map). You can soften/blur that if you like, and
then repeat the depth render with this new image using hf_gray_16 output. You
should wind up with a less 'crappy', hi-res bitmap to use. Just be careful with
your file names. :)

I tried it and it looks great! A huge improvement!
