Nice use of image maps, though the image map on the table is what causes the
strange look. The problem is that the image map has some lighting "built
in" to the photograph (light coming straight down from the top), and that
lighting does not correspond to the true lighting in the scene (light coming
more from the side).
Anyway, I was wondering if you used 'real' or post-processed focal blur?

Actually, repetition are more visible on the stone vase but this is due
to
a mistake from me :).

I use radiosity though. But nothing is really perfect in this world :).

You are right and I know this, this is why I say to look the upper part
:).
I will perhaps do another with real model of plank with each one with
its
own texture. This would noramlly be better.

These are sweet. I did a coffee cup texture like one of these
a while back, but never finished the sceen (or the macro).

Hello All,
Thanks for your comment.
For the textures, I use a "new" (at least for me) method
which mix procedurial and image_map. In this way, if
you don't make mistake :), you cannot see repeating pattern.
The adventage is that you aren't obliged to use huge image_map.
This doesn't work with all image_map, it depend on the kind of
pattern on the image, but it work great for most.
You want the method?
It seems I can hear yes ;).
This is very simple and I suppose I am not the first to
experiment it. Many variant are possible and perhaps some
of you will improve it (this is why I give you the method ;)).
You make a layer texture:
1) on the first layer you put the image_map (well corrected
in photoshop etc...), the normal (bump_map which is just
the same picture but in grey scale and with much more
contrast) and the finish.
2) on the second layer you make a pigment map, you can use
what you want as pattern with turbulence or not (but if
there is turbulence, you need reset children, thank Nathan!).
Here I use two entries. For the first entry you put a simple
color rgbt 1.0. For the second entry you put the same image
map, with normal (bump_map). And finally you add the finish.
I think it's all :). Pretty simple.
In the beginning, I though about that to make some roughcast-like
texture, with some part which are gone etc... But it works for
other kind of texture too :).
Some of the image_map are found on internet, the others are
photos made by me. Simply go to the link part of the povray site
to have good links to really good textures. Some are seamless,
others need to be processed (if you need explication, this
will come on the GenOrb site http://www.genorb.be.tf. But I am
sure that with Altavista you can find this information on
the web). But in all case you need to improve their histogram into
photoshop (thanks Gilles).
Fabian.

I haven't seen a vase rendering this good since the 3 oval shaped and glazed
vases someone did long ago standing amidst ground fog on cubic stands (here,
at AOL graphic libraries, someplace). Had you done likewise I think this
would be incredibly life-like. Well, still-life life-like, ha ha. A small
gap between boards and bottoms of these would do good I think too. It's
that fuzzy/sharpness contrast that distracts.
Actually, it's not that the others were so real as they were artistic and
were done with what was new back then, POV-Ray 3.0.

Very nice wood texture!
j/k out of jealousy. Extremely impressing vases!
