Hello,
Here's the beginning of a sea scene I've been working on lately. I'm
fairly happy with it so far, but I'm not really sure where to go with it
from here. Thought I'd share, and if anyone has any comments they're
always welcome.

Forgot to mention, posts are created using Christoph Hormann's IsoWood
macros, and Evilsnack's Basic Clouds tutorial provided helpful guidance
for the clouds.

Looks OK as is.
I like your sig, but you can make it shorter: remove the version and the
global_settings. Did you notice that changing the smples valus makes some big
difference on the image?

I enjoyed it, depressing as it may look. :)

Looks good so far. I am not too sure how to do this, but I suppose some
ripples around the posts would improve the water.

Thanks! Thanks for the suggestions, I was wondering if it might be a
bit too long. I did notice that, and it surprised me. I haven't seen
that make such a difference before now. I'm assuming that the result
would converge at some higher setting.

Thanks very much! I was shooting for somewhat desolate, though I wasn't
thinking depressing :)

Thanks, and that's a good idea. The "ripples" pattern uses random
locations, but perhaps some sort of radial sine waves... now I have to
try it! :)

I was sure I had it somewhere!
I remember I asked about this some years ago. Jim Charter provided the
following piece of code:

It's because you use the crackle pattern with a color_map that goes from 6 to
zero over 0.03. With more samples, you follow the actual pattern more closely.
There is about no difference if you go from 20 to 40 samples, so, yes, it does
converge with larger values.
Want to shorten a bit more?
color_map{[0rgb 6][.03rgb 0][1rgb 0]}
is the same as
color_map{[0rgb 6][.03rgb 0]}
