So, here's the next step.

Tilted the camera, worked on the lighting, the water, the textures, the
models... Added that thing which'll go down the drain as well. Quite unsure
what to add now, if I want to tinker with the colors and lighting some
more... I guess I'll have to give it a rest for a day or two to get a new
look at it.

Comments and suggestions appreciated! :-)

Tim

Looks good. A few suggestions:
The water should form a spiralling whirlpool as it goes down the drain.
It needs a lighter background, black is a very unnatural colour for this 
subject.
The sink looks too clean, particularly around the soap where I'd expect some 
soap scum showing where soapy water has run down the side from the soap 
dish.

Also, is the refractive index right? Water should be around ior 1.33, I 
think. I have to say the water looked more real in the first one, I think 
it's just because there's more highlights reflecting and refracting in the 
water.

Ouch! Each time I think I made something nice, Tim comes along...

It does, though it's less pronounced now. Might have to work a little on
that.

My brother commented as much, I'm thinking about it, though I do like that
its slightly off the usual rules.

Texture-detail is something I haven't really begun with yet, though I was
wondering about leaving everything looking shiny and new. I like the
contrast of the story I'm trying to hide in the image and the look of the
image (sad vs cheerful/bright).

Refractive index is right, it's at 1.34 at the moment. I'm thinking about
adding a lightsource just for the water to catch some highlights.

Thanks for the comments, I'll ponder them and look what I can do. :-)

Here's an attempt at that. Quite honestly, the refraction and viewing angle
obscure the view on the mesh so much that I don't think the extra workload
is needed. I've written a small script to generate an array of points which
aren't spread evenly like in a heightfield, but are closer together at the
center where the vortex is, and further apart at the edges, where there's
less detail. I then twisted the vortex's axis a little with it being
displaced, so the vortex doesn't go straight down, but swirl towards the
drain.

Might be that I've got to add another lightsource for highlights to show the
displacement on the vortex, but if that doesn't do much, I think I'll go
stick with the simpler heightfield. Some of the caustics (non-photon-mapped)
are more pleasing to me visually in the old version.

Tim

I thought I had that covered with "different style". :-P

I'm not sure, but the way I say it, people are different, have different
talents, and different ways how to do things. Putting the marker "better" or
"worse" on things often isn't really what's asked for.

The one thing my brother asked as well. If you'd take a closer look, you'd
see that there's a heart in the drop. Add the title "Down the Drain" and

There's a heart inside of it, going along with his "Down the Drain" 
theme.  I didn't see it right away, either; maybe you should make it larger?

I am pondering about that as well. Trouble is, when I make it larger, the
relationship drop to faucet doesn't work really well anymore. It's not final
anyway, as I'm also thinking about making the drop still attached to the
faucet and just about to drop off.

I originally thought the red would attract the eyes, but I can see that the
resolution at which I posted does throw it off a little. Maybe I should also
find a way to attenuate the border a bit, that might help as well.

Tim

    Your drop is much better than my drops in my last image. Mine are just 
boring old water drops...  :/

      Nice idea Tim, following this enthusiastically.  :o)

On second thought, I like the current size.  It will be much better, of 
course, at a higher resolution.

Anyway, if you do decide to increase the size of something, I'd go with 
making the glow around the drop stronger / larger, rather than changing 
the size of the drop itself.

Of course, it's not my image to begin with, so take this with a grain of 
salt :)

You can have mine! The size is probably off, so you should scale it at the
end.

  blob{threshold .5
    sphere{0,2,1 scale .02*<1,1.25,1>}
    sphere{0,2,1 scale .01*<1,2,1> translate <0,.03,0>}

That's something that is easily overdone, and all of a sudden you get a huge
red blob in your image. If I increase the size, I also have to make the
gradient smoother, so as not to make the red dot a red GIANT. But I'll see
how it'll turn out. I've been told to try for a background with tiles, and I
have to see how that works out.

I always do. I like to hear opinions and ideas, as they often lead to new
ideas or help improve the image. But as much as feedback is always
appreciated, the final choice is always mine. And I guess everyone knows
that and does it that way himself. :-P

Without reality-checking here it looks much like I'd expect it to. I don't 
think there's ever much visibilty for something like this. Might be larger 
than usual for the depth, if anything. Seems to me that the vortex is 
typically very thin, hardly breaking the surface, until the surface gets 
near the drain. So maybe this sink would be a little scary for people with a 
phobia about such things (sister's daughter did).  :)

Trying to remember about twisting directions... I know it is commonly 
thought that the northern and southern hemispheres of the planet have their 
own direction but it's apparently just a random thing instead. I forget. 
Something about no relation to weather that is influenced by earth rotation 
instead.

   I wondered how long it would take for someone to bring this up.

   The rotation of the water has nothing to do with the rotation of
the Earth or anything like that. It's purely a question of geometry
of the sink, the pipes, initial water movement, etc.

So, here's a quick (heh, 7hours and not done yet ain't quick!) test with
focal blur.

The render wasn't complete yet, so the lower 120 lines or so are basically
just a blurred version of the standard antia-aliased render.

Anyways, I think the focal blur adds a lot and I'll keep it for the final
render. Now I'm getting to the spot where I'm unsure if I want to add
anything and I *really* should give it a rest for a day or two, and take
some more comments and suggestions. A good friend of mine wants to say
something as well, but as she's not here at the moment, I have to wait for
her as well.

The tiles behind the sink required a little change in the spotlight's
point_at, which in effect caused a little more lighting variance in the
lower left corner. I'm thinking about pushing it a little further (either
via texture or via lighting changes), but we'll see. As it is now I think
I'll be experimenting with some "less shiny-new-clean" textures to check if
it enhances the mood I'd like to create. I also want to try and add some
waterdrops onto the surface of the faucet near its base and on the sink.

And for those wondering, the waterdrop is now modelled with Silo like
everything else in the image besides the heart, the water in the sink, and
the foam on the soap.

Tim

I can only congratulate for a STUNNING image... I do have a couple of 
suggestions though:

1) Raise the ambient lighting a little. I think the image is a little dark.
2) The taps only have two knobs... I've never seen taps like this... Taps of 
this style seem to always have four knobs.  I think this would also round 
out this area of the image.
3) Where is the plug? In sinks like this, the plug is usually chained to a 
attachment just above the overflow... This would give you the opportunity 
for some real nice chain.
4) I think there is a little too much focal blur in this... the soap is a 
bit too blurred.

I agree with you about using some dirty textures rather than the too shiny 
ones...

Even as a WIP this image is bloody impressive... you have more patience than 
I do!

That's often a problem with what monitor you're watching it on. Personally,
I like it like it is, but I might try to make it a tad brighter. I'm not
sure if that creates a wash-out on the already bright parts, but I'll
certainly look into it.

Yeah, should give that a try. I always like doing things slightly off what
you're expecting, but you're right, maybe it would balance that section of
the image.

Actually, I do have a plug fitting the drain. But then I decided to leave it
away, as if to say that there's no way to keep that drop going down the
drain. Might have to create the chain in any case, to make the absence of
the plug more obvious.

It's a difficult choice. I kinda like how the tab gets blurred, but then the
soap gets blurred to much. I surely will toy around with those settings,
they were the latest addition and haven't been tweaked as much as other
stuff.

Thanks for the feedback!

Everything you ever knew about spinning water that ain't so:
     http://www.ems.psu.edu/~fraser/Bad/BadCoriolis.html

A similar fallacy leads some New-Agers to believe that the tides affect our
body fluid.  It's sometimes scary all the things we take for granted that
are totally bogus. Here's a bunch:

Hi Tim,

It's looking excellent.

In terms of dramatic effect, have you considered placing the heart deep in 
the vortex, just on the brink of going down the plug-hole? The drop forming 
on the tap looks like it leaves a glimmer of hope that one could salvage the 
situation by plugging the hole. You could even have a faint red spiral 
coming back off the heart and maybe a dagger inside the water drop ready to 
fall and slice the heart into pieces before it finally drops out of sight.

Hope these ideas raise your spirits ;o)

All the best,
Chris B.

Initially, I wanted to place something near or even in the vortex. As for
the plug, Rarius mentioned that it seems missing. I'm currently thinking
about adding part of a chain to the faucet, which should show more clearly
that the plug is in fact missing, there is no hope for rescue by plugging
the vortex.
As for the dagger - I like and want an image which, overall, gives the
impression of a nice, clean and bright environment, and a friend of mine
today told me as much. The heart is the tiny drop that'll tell the story
behind the title "Down the drain".

> Hope these ideas raise your spirits ;o)

Well, the image and the work on it is more of a distraction. I'm too much of
a thinker.

Tim
