aren't barrels like that made from +/- 10cm wide (4 inches) wooden strips?
not sure about that, but I don't really find the barrel very realistic at
the moment (not taking textures into account)
it seems to be early in the morning (?) so maybe the light should be a
little bit more reddish?
love it though...

Jaime:
This looks really great, as usual. :)
Am I right in thinking that the table top uses Christoph's IsoWood include?
I have to say that I am with the others in noticing that there is something
missing with the barrel. To me, it looks like the surface is a little too
uniform to truly look like the real thing.
Otherwise ... awesome!

Not only. There is a long tradition among the christian painters to have
the light above and from the left. As christians invades nearly
everywhere, it has become traditional lightning of most past artistic works.
It's mainly due also to the fact that to avoid being dazzled (*), the
painter has to turn its back to the sun, and in the north hemisphere
the sun is on the left the afternoon.
If you want to trigger a 'early morning' feeling, you put the light
low on the right, but the light is better later in the day...
*: as well as avoiding the representation of the sun, and the
contre-jour for the subject.

Hi all:
Many thanks for the good criticism to all:
Bill P.:
>Perhaps a little discoloration of the barrel wood above and below the
>'rusted' barrel rings.
I don't know what exactly happened to the barrel texture, but there are 4
layers, one of them corresponding to the effect you mention. On the tests
it showed up very well, but the effect has almost dispeared on that
render... but I don't know why!
Xplo:
>The light coming from outside seems awfully cold.
Ah! You got me... previously it was a fluorescent light, that's why it is
a bit greenish. I forgot to replace it with a sunlight color.
>You might put a couple screws/nails/some kind of fasteners in the window
Nice suggestion! I was searching for this kind of "little details"...
>The barrel rings definitely don't look like rusted metal to me. I'm
Good criticism again: will see what I can do.
Daan:
>aren't barrels like that made from +/- 10cm wide (4 inches) wooden strips?
Hmmm... I really don't know. I've done it without a concrete model, and
only looked at reference pics for the rings placement: I forgot to pay
attention to the strips size. Good detail! I will research a bit...
Aaron:
>Am I right in thinking that the table top uses Christoph's IsoWood include?
No, it's a heightfield. But the effect achieved it's nearly the same.
>missing with the barrel. To me, it looks like the surface is a little too
>uniform to truly look like the real thing.
Yes, the mesh deformation function needs more work to look like real wood
grain. I'm trying different patterns but it's a bit slow to test because I
must generate the mesh at the final resolution each time: the pattern can
look very different at lower triangle counts.
ABX:
>I'm really happy I could help with such great image.
At least you helped to keep in the barrel, that's sure! :)
>Grandmother with frilly dress ?
Hmmm... I was thinking only about the frilly dress or apron, as the
grandmother is beyond my povsibilities.

Great explanation... is somewhat scary to think that things you do
unconsciously, are really "guided" by cultural archetypes.

I had no idea that this was so! When I start putting together a scene,
I always start with the light source in an above left position. Now, I'm wondering
if I'm doing it subconsciously, having scene so many paintings lit in
this way ...

That's correct but I have always painted, drawn and rendered with the light from the
right!

Excelent job so far, apart from the things that you want to improve (which I
would have mentioned if you hadn't), the light looks a bit too blue, and
sould maybe have a touch of yellow.
The brass texture on the scales is beautifully done, particularly the
dust/fingerprint effects.
