Well, its been a while since I have posted, and I haven't been able to
keep up as much with the goings on in the tracing community as I would
like. But thats how life goes sometimes.
This is my most recent attempt at photo-realistic raytracing. As you can
see, lighthouse on the right open sea on the left. I am pretty satisfied
with the lighthouse/cliff portion of the scene, but the rest of the
scene seems to be leaving something to be desired. I think that its
because there is so much open space, but Im not sure. I was thinking
about putting the shape of a sailboat out there to break things up a
bit.
Another thing that bothers me about the image is the clean line between
the ocean and the sky. It seems too artificial. And could soemone point
me in the right direction of some good cloud tutorials. I have seen
several scroll by on the newsreader in the past months, but havent paid
close enough attention to my own tracing needs to know that I wanted
them. I think that I saw something a while back about media method 3
with mega-pov. The images that I saw with that is where I was hoping to
head with the sky in this image.
Questions, comments?

I received this from a joke-a-day website and found it oddly appropriate to
your post, Paul.
Naval Operations
The following is an actual radio conversation released by the
Chief of Naval Operations:
#1: Please divert your course 15 degrees to the north to avoid a collision.
#2: Recommend you divert your course 15 degrees to south to avoid a collision.
#1: This is the captain of a U. S. navy ship. I say again, divert YOUR course.
#2: No. I say again, you divert YOUR course.
#1. THIS IS THE AIRCRAFT CARRIER ENTERPRISE. WE ARE A LARGE WARSHIP OF THE
U. S. NAVY. DIVERT YOUR COURSE NOW!
#2. This is a lighthouse. Your call.

Nice rocks. You might want to try a nice ground fog to soften the edge of
where the water meets the sky. If you have SuperPatch or MegaPov, you can use
angle-dependent reflection to make the water more realistic.

The only thing scarier than being in that light house would be to tree climb in
that cliff-edge tree. Or maybe it would be to rock-climb up that cliff (I
wouldn't do it anyhow).
Looks like it could make for a great scene. That water just isn't looking
anything like water to me for some reason, perhaps the grainy appearance is why,
not sure, but out of all the different waters I've seen this one isn't making me
think it could be water. Almost strange in that.
The lack of reflections of the sky maybe? Or that it might be opaque instead of
somewhat clear down to a certain depth? Don't know why that is.
Anyway, the ground fog suggestion is what you need most to get rid of the
perfectly lined horizon alright. The media clouds is something I haven't done
much of, so I'm no help there. And I haven't been yet have I? Hmmm.
The lighting is also throwing me off, it appears to have sunlight coming from
far left low in the sky and it's very weak almost like extra strong moonlight.
If you have a sky_sphere in use there that might be the reason for the odd look
to that since it can only be fully ambient with no change according to light
source position. If a regular sphere is used instead then that can be brighter
nearer the light if ambient 1 isn't used in the finish. And if media is going
to be used I think you might be better off without sky_sphere in there.
Back to the water. Something that can be good is to use a texture_map, large
scale bozo for example, containing a few different water textures in it to
signify varying surface perturbations over a large area. Wind and no wind for
instance.

I like it. I think the lighthouse would look nice if it was slightly concal
rather than cylindrical, maybe with a nice white-washed brick material. If you
could use some media with a spotlight to simulate the lighthouse light that
would be fun too. Animating the light going round would also be fun. I like
your trees and I especially like the cliff, is that an isosurface?

I like to use huge spheres instead of planes if I'm going to have a wide
horizon. You don't need much of a curve, just a little bit, to make
things look much nicer in that respect. I don't know your scale, but
something like:
sphere {
<0,-20000,0>,20000
texture { whatever }
}

this is pretty cool -- i think it'd look cool if you experimented a little,
like changing the water to sand so you'd have a desert instead -- i
dunno...good job anyhow

I have a couple of suggestions:
foget the sky_sphere, instead, add a constant fog in a color of blue with a
distance of 10000
add a ground fog with a distance of 7000
if you want some fog over the water it can also be added (not recommended
not doing a night scene, would look real)
the clouds would be two identical very large spheres ( scale
<6000,8000,6000>) with media. the densities should agate or something like
that and have slightly different turbulences. now CSG the spheres with
intersenction. you should get pretty good clouds, but a LONG render time...
I think the coulds are media type 3, but I'm not sure.
about the water:
make the plane hollow, and add an absorbtion media that is the opposite of a
greenish blue (did that make sense?) now add a large sphere or cylinder
(like the clouds) under the plane. this should make the water that's closer
to the land lighter than the far away ocean.
I'm not sure if that is what you wanted, but I hope you can use it.
you will also want to add a light source that does not interact with media,
so that the clouds dont create shadows all over the place. Or you might
want the shadows....
have fun!
