It looks more real every time.
It also reminds me of the old harbour in Chania in Crete.

Thanks, Stephen. That is what I like with wips; and I always keep a copy 
of intermediate stages in order to assess progress or dead ends.
Each time new problems arise too, together with new ideas of course ;-)

I didn't know that town, but looking at images of its harbour, there is 
a strong similarity indeed. Seems I am on the right track. Maybe I can 
find some inspiration there too... translating back over a millennium.

Until you need the disk space ;-)

A couple of months ago I cleared out about 4 gigs of HDD space. Not to 
worry I still have them on Backup. If I ever get round to looking at 
them. :-)

The photos I googled just now don't show what it was like 25 years ago. 
It is the long buildings that remind me of the harbour. Then they were 
just unpainted stone. Now if they are still there they will be decorated 
for tourists. :-(

I like the grass growing between the cobbles, a nice touch.

Yes, the grass is a very fine addition as are the additional people, the
luggage, and the flag. May be you can modify the height of the grass by random.
It's just an idea...

Yes, I can imagine that. As long as tourists stay away from Gancaloon 
the stones will remain bare or plastered (subject to erosion. That has 
still to be done.

Yes, but - like others have said - there is still some work to do.

Flag? it is the sail of an incoming ship ;-)

The grass still needs work. There is a random height control already 
present but it probably needs to be made larger. And other things too.

Absolutely. It was not yet implemented here because I have some problems 
to get the patchiness right as I want it, but it should be there next 
time, with thanks to Kirk Andrews who wrote the code in the first place.

I will. Once started, each scene gets a momentum of its own and I need 
to take advantage of it before it begins to slow down.

   Yes.. to me, at first it seemed to be pondering about purchasing the

Looking better and better.

There is a place called Sudak in Ukraine.  It has a Genoese fortress on 
a headland to one side of a bay where a small town and harbour are under 
its protection / control.

Very similar to your location and style.

Keep it up!

I seem to have seen this before.

1) What is causing these /nice/ rows? becoming visible when I increase 
the number of plants? They were already present in the original image 
but less conspicuous.

2) And why do they not correspond to the eval_pigment function selection 
(black corresponding to the inter-stone area)?

3) No difference with noise_generator 2 or 3.

  Difficult to say without the code... do you use totally random point's
over the floor to evaluate the pigment?

Yes, flat distribution. I either used rand, RRand, or Vrand_In_Box, with 
identical results.

I have now found that eval_pigment is the culprit. I probably need to 
rotate by 90*x the used image_map before testing the locations.

Lunch was the trigger :-)

I have made the mistake before: forgetting to rotate an image_map by 90 
degrees around the x-axis before using it in a scene. As a consequence, 
eval_pigment did not do its job correctly.

This is now corrected (see image).

   Ah... now makes sense: you were evaluation the side of the image,
which is usually a bunch of lines... ;)

A lizard. I have orientated it differently now: more light, less shadows 
(but not its last transformation I guess).

Thomas, I really like this concept and the scene is coming along beautifully
(love the grass!).

After reading a previous post, where the red sail seemed like a flag, it
occurred to me that the camera is at the height of sailor's thighs, and a
slightly higher (+y) camera position really would help to better spacially
orient the incoming ship, the buildings across the water, and the distant city.
Of course, a bit of atmospheric haze and focal blur can work wonders too :)

Cheers

I like the progress on this image, very impressing. The axis between the two
men; the invisible line between their eyes is a main composition element that is
nicely echoed by other lines, and there are lines normal to this (the rope at
the front of the boat especially) that binds the composition together. The
clouds make an arc that is echoed in the line of the bright hill in the
background. The direction of the lines in the foreground also contributes in a
good way.

A few points on the composition, if I may: the lizard seems to me to point out
of the image. I believe it would be better if its nose was turned to maybe seven
or eight o'clock (in the image plane, that is). That way it would keep the flow
of the composition back into the image. The lizard has become a very important
element in this image, and should be placed exactly right. (Have a look at
Rembrandts anatomy lesson; the book on the right stops all the gazes of the
men.)

The light horizontal line of the edge of the dockside (is that the correct
word?) (in front of the man on the right) is broken by the man and the packages,
but seems a bit even; the stones could perhaps be a little jumbled, and if the
camera is turned slightly, it wouldn't be exactly horizontal as it looks now.

The hill in the background - is it perhaps too bright? I'm thinking it draws the
attention into the middle of the image and not letting the eyes wander around.
The brightest area in an image will often get the most attention.

But maybe I'm wrong about these things, this is your image, after all. I'm
looking forward to the next versions.

Thank you Robert! Things are going fine indeed and the more I work on 
the scene, the more there is to do in addition, including rethinking of 
older concepts.

Yes, that might become necessary, although I like the low point of view, 
as if the observer was sitting down. I shall have a few try outs and see 
where this gets me.

There is a faint haze over the whole scene, less visible here than in 
panoramic views because everything is nearer the observer of course. 
However, I can play with this a bit more in this scene, increasing the 
number of controls I have to tweak while exploring the city ;-)

I am not too keen on focal blur in these kind of scenes. I do not want 
to focus on a particular area but leave the viewer the possibility to 
discover his/her own focus as it were.

Thank you indeed for your careful analysis! You have seen things I had 
not been aware of. Some compositional elements happen just by chance 
(the clouds for instance), others seem to be more or less subconsciously 
controlled.

Like I said, the lizard's position was not yet fixed and I fully agree 
with your observation. In the mean time, I have already rotated it 
inwards to the scene. I scaled it a bit down too.

At present, the quay edge consists of a simple image_map (within a more 
complex layered texture of course) on a rather simple mesh. For this 
view, I agree that the stones need a more interesting aspect. Can easily 
be implemented :-). This viewpoint is very straightforward and a bit of 
camera rotation is certainly a must here.

Yes. The texture of the hills has not really changed since I began 
working on this project. I agree about the brightness (and some other 
things too I have in mind). The texture needs an overhaul.

No, you are perfectly right and I think that I would have made some 
transformations in that direction anyway, but it is good to hear it from 
somebody else, giving confirmation to doubts or enabling me to see 
things I have been blind to. Thank you for this.

There is still a lot of work to do on this scene, in terms of 
(additional) objects, textures, layout... and story telling.

I like it too, but not as the observer is sitting: the observer is on a
small boat on the otherside of the quay, maybe stepping up on that quay
soon.

I'm still hesitant on one point: the moire that appears on the parcels.
It is somehow ok, as reflecting the texture of the material (not in
Pov-sdl meaning),yet it's an artefact shooting loud about computer graphics.

I see it more as a common digital/video artifact, not specific to CG. More AA?

No, there is no water behind the observer; there is the extension of the 
city walls, so the observer /is/ sitting down in this version ;-)

I don't know what to do about it. It is the cloth texture image_map and 
normal_map doing this of course. One possibility is making the cloth 
coarser.

Do you need to do anything about the moiré pattern? We see them in real life
with our own eyes. Although in materials they tend to be very fine ones.

One thing that is bugging me is the water. I agree that in a river or estuary
you do get outflows of mud and silt after a heavy rainfall. But I think that the
brown water in the harbour is more like an industrial scene. Thinking back to
small harbours that I have seen, the water was always crystal clear. You could
even count the fish.

Hey, you choose what I can see on the picture, but you have no power

At least, not until the thought-police come into action and break my

True, but I can at least try to reduce a bit the worse effects. If not 
satisfying, I shall leave it as is.

Good point, but remember that this harbour is open to the river, not to 
the sea. There may be sea water influxes from tides (feeble in the 
Mediterranean) or from sea wind, but then that would probably also 
become murky from the shallow bottom... and I don't know how well the 
sewage system of Gancaloon functions ;-)

As a good comparison, how clear is the Nile water close to the 
Mediterranean? Well, watching through Google Earth, not too murky it 
seems... I shall have to decide how murky the Yann is.

LOL! You remind me of that story about Asimov (iirc) who attended a 
lecture about his own work, where the speaker explained all the 
different things that could be deduced from the work. Afterwards, Asimov 
told the speaker that he had never intended all those things. At which 
the speaker said: "What do you know? you are only the author."

> P.S. : now if you can justify a mirror in the scene, I might be stuck!

   It can be as murky as you want, but consider de-saturating a bit the
brown color (I would even make it more greenish).

I don’t want to nitpick but as usual I will ;-)

Remember a harbour is designed to give ships protection so the water 
will be relatively calm. Any silt would drop out. And from memory, silt 
enriched rivers tend to be cloudier in the centre where the flow is 
faster. Going from the layout of Gancaloon in your post “Transition 
between two medias: Final result” the harbour is well designed.
But as Jaime said “It can be as murky as you want”

There is silt and silt. The finest particles will remain in suspension 
longer and, in the end, you will not see much difference between the 
central flow of the river and its borders. Well, close up maybe some but 
not dramatically so, with some transparency as a bonus, but all depends 
on the power of the stream.

Going from the layout of Gancaloon in your post “Transition
> between two medias: Final result” the harbour is well designed.

Indeed, but now you are making my work very difficult ;-)

The water transition between river and sea has been designed on 
"planetary" scale. This means that the whole water surface you see in 
the scenes is a huge sphere. It would be nice to control the river water 
from point to point but that would mean a break up of the sphere and a 
difficult design in the end. I am not (yet) up to that I must confess.

> But as Jaime said “It can be as murky as you want”

Yes, and that is the approach I would prefer for the time being.

Yes, that was one of the ToDo things on my list. I left it as is because 
I like to imagine the muddy character of the river, at least during 
certain seasons of the year. In the end, however, I shall have to design 
a whole scale of different hues reflecting those same seasonal changes.

And you say that *I* am making your work difficult. Look in the mirror that you
promised Le_Forgeron.

PS A polished shield would make a believable mirror.

I didn't cross my mind, but yes, there might be some (smelly) similarity

I have not looked in a mirror for ages... In fact, I am not even sure a 
mirror would reflect my face... ;-)

Interesting idea. First I need to texture the walls behind the camera.

Find the differences :-)

Many questions have been addressed (sort of) some remaining, notably the 
fact that I still need to uv_map most of the ship's textures.

I did find your earlier camera view much more interesting. This one is 
just conventional and while everybody knows the name of the director, a 
great cinematographer can make a huge difference ;)

I liked the lower camera better.

The burlap is much improved.

The statue bronze could be a little darker, unless you want it to blend into the
background.

The red of the sail strikes me as too saturated. It seems glaringly out-of-place
and a bit too attention-grabbing.

I think I've seen the kid sitting on the wharf before, in another CG, in the
exact same pose.

Yes, that was also my verdict, but I had to show this version to be 
believable.

It is a stone texture, not bronze.

Absolutely. I have already been busy fading the colour.

You have an excellent eye for details! ;-) The kid appears in a TC-RTC 
scene: September 2009. He is place holder for the time being and will 
probably change a bit later, at least his clothing.

I don’t agree. It is all to do with the art of illusion. IMO

I would have put a camera crew in the background. ;-)
