So it is supposed to be a German 'Autobahn' - a few notes on realism there:

- the white strip at the outer (right) side of the road seperating it 
from the 'Standstreifen' usually is much broader than the other 
interrupted strips.

- those white (plastic) posts on the side of the road have the black 
strip at the top going upward from inner to outer side.

- the trees are quite large and no german road authority would allow 
such large and old trees to grow that near to a highway. ;-)

Apart from that great image of course.

Well, for something like that, it's not that hard: the road can be just a plane
with the image projection_map'ed onto it:

//projection_map
 #declare Pigment=function {pigment {image_map {jpg "autobahn2b.jpg" interpolate
2 } translate -.5}}
  // perspectiveprojection: Px=x/z, Py=y/z, Pz=0
 #declare Projection_pigment =
   pigment {
      average
      pigment_map {
         [function{Pigment(x/z,y/z,0).red} color_map {[0,rgb 0][1,red 4]}]
         [function{Pigment(x/z,y/z,0).green} color_map {[0,rgb 0][1,green 4]}]
         [function{Pigment(x/z,y/z,0).blue} color_map {[0,rgb 0][1,blue 4]}]
         [function{Pigment(x/z,y/z,0).transmit}color_map {[0,rgb 0][1,transmit
4 ]}]
      }
   }

  plane {y,0
  texture {
   pigment {Projection_pigment}
   finish {ambient .5 diffuse .5 brilliance 2}
   scale <4/3,1,1>
   Reorient_Trans(z, camera_look_at-camera_location)
   translate camera_location
  }


that should do the trick.

I think it is mostly the foreground trees that give it away. It is not 
that the trees aren't believable,
  it is that they are identifyable raytraced tree "species".
  That and a certain regularity to the general "randomness"  and
perhaps some flaws introduced by photography itself.  But suppose the 
history of art had proceeded directly from painting to raytracing and 
photography had never existed?

Oddly, I've never been attracted to cars, never have owned one, never 
painted one, only modelled one once and it was barely an offhand four 
hour shot at it.  But I *love* highways.  And highway scenes.  I used to 
hitch-hike extensively when I was young.  And the poetry and drama 
intrinsic to highway scenes always crowded my imagination. The tensions 
of mundanity and modernity, engagement and alienation.  It is in Gilles 
work a lot also of course.

Very interesting subject from a raytracing point of view too.  All the 
regularity of the engineering versus the randomness of the texturing.

Quick joke, but actually a pretty cool idea.  And, with all the car 
modelling that goes on, it is not something that has ever been done that 
I know of.  ( althought no doubt I'd be that last *to* know )

I am not sure I agree,  While other angles for the shot may well get 
some  fruitful results, there are some great compositional elements at 
play here.  Not just the symmetry you mention, but the rectilinearity 
with the picture plane of the signs, wires, and shadows of the wires, 
that tease the eye in a subtle way.  As far as what it at the 
convergence point, I think there is some very interesting things, or 
themes that are interesting to me at least.  That is the sense of detail 
that is barely perceptible and therefore puzzling to the mind.  I try to 
identify the nature the structure of what appears to be a distant span 
of some sort.  We always gaze toward the horizon a try to discern the 
most distant of details.  It is often key to our survival.

The center of the road (between different-way lanes, I mean) somehow 
doesn't look photorealistic. Maybe it's too perfect - the fences are 
totally straight, theier posts are all in nice line etc.

But noticing that AFTER I realized that the pic is traced, it still 
didn't keep me wondering which one of cars actually is added to the 
photo :p.

excellent. my only slightest criticism is that the blue signs look like they
are lighted differently from the rest of the scene. I don't know how to
explain it other than, it looks like they were cut and pasted in from a
different but similar scene.

the shrubs on the median between the two sides of the road look excellent

I spent a year in Germany while in the (US) army in the early 60's. 
There was no speed limit on the autobahns.  :-)    Ordinary streets yes, 
autobhan no.

Of course, being 45 years ago, this may have changed by now.  Our German 
friends in these newsgroups can correct me if this is so.  ;-)

Since there were no hostilities at that time, it was a very enjoyable 
year.  (Except for the "annoyance" of being merely a private in the 
military.)   :-(

   Yes, and not only in Germany. I'm still using the first material_map I
painted to test the technique. I'm planing to create a better version
with another POV scene instead painting it: I'm really bad hand painting
the little details...

   That object was also a quick placeholder... but thanks for pointing

   These are good suggestions, and actually, I didn't even think on many 
of them... I like specially the birds idea: it should not be that hard 
to create some silhouettes with Wings3D.

   I recommend using "Autobahn" by Kraftwerk as background music for 
this scene, of course.

Hey Jaime!
Don't you know what happens to the guys who post photographs here?
They are poured molten tar on them, covered whith feathers, tied on a

Now I stop kidding. Thats fantastic!!
The only critics I can do have yet be done: sharp shadows, blue signs too
clean.
And tree trunks slightly too gnarled (end trees too tall and close to the
road)

But WOW I can smell more or less well burned gaz , heated oil and tyres (I
think I'll go too the seaside to clean up my lungs lol)

breathtaking.

From my wacky perspective, somehow this would be even cooler if you were to 
add to it something that ain't photorealistic or overly stylized in 
construction.  That would make it extra cool.   If you were to say put this 
image as-is  on a subway billboard advertisement, who'd care-- it's just a 
photograph.

The pavement is very good looking.  I'm not sure about the autobahn, but 
normally worn asphault has a pattern of cracks that I haven't found a good 
way to simulate.  Concrete has bigger 'holes' that at highway speeds don't 
make a thump as much as you think considering how deep they can be.

I also thought the way the lane wear was done was excellent.

   Yes, you know me! I used the same trick but a bit specialized for the
material_map which uses it. The base is a concrete photo from
imageafter.com, with a bit of turbulence on y, and a gradient x on top
for the dirty on the center of the lanes (not very well aligned, indeed).

   I like cars, but not as much as I like driving. But I don't like
driving on the highway... it's boring: I prefer the city or rural roads.
I did a highway scene because it is easier to model than a city or a
rural road.

   I think it's because the saturation of the image_map is excessive

Yes I see that now you mention it. I haven't used trees yet and they
do look a bit gnarly. 
I thought that the shadows were just a bit off as if the sun was too
close. But then I was looking hard for a clue. What decided me was
when I tiled it on my desktop as wallpaper. The symmetry is a

Does that exclude paintings made with the help of a camera obscura?
Which leads onto "no television" no computer displays hence no
raytracing!  Hmm! Big thoughts. I know, we suspend disbelieve. 
The pre Raphaelites never got started and impressionism leaked into
mainstream GUI's. The Dada school designed keyboards and all the keys

Yes, I later wished that I'd made that point clearer.  Identifying it as 
a raytracing had a lot to do with being able to assume it was, then look 
for clues.

Yes, a photo with high degree of symmetry would spawn a different set of 
questions.

Oooo, good example!  That would mean an exceptional degree of empirical 
information, but still, no matter how passive the artist's hand, via the 
mind, it would introduce some regularity.  Meanwhile, the viewer, 
knowing the picture was the product of an artist's hand, would demand 
less in the way of empirical randomness before experiencing verite.

Ever heard that German 15th century painter Albrecht Dürer is considered

I think that's shown in the Impressionist movement, if I understand
you correctly.
This goes down the old "we see what we expect to see" road, which is
fascinating. IMHO Huxley (A) was on the right path when he said that
the mind is a reducing valve to the universe. It enables us to have an

I saw it when it was first broadcast in the UK. Hence the mention of
the camera obscura.

There are speed limits on the "autobahns" in these days. But when you're 
  lucky you can still find some parts that don't have any speed limits. 
But it isn't fun to drive, because today the "autobahns" are too crowded 
and you have to be so careful to survive. ;-)

Just my two eurocents,

All it takes for me, is that I get "turned around" in my sense of 
directions.  Suddenly an environment I am used to "looks totally 
strange".  Yesterday I was walking around a park here called Marcus 
Garvey Gardens.  It lies directly across 5th Avenue.  The avenue just 
stops at one side then continues again on the other side.  I was on the 
north side of the park where 5th abutts but I *thought* I was on the 
south side.  Total disorientation.

I loved Huxley's writings on art.  I especially liked the line that went 
something like: "If religion is the opiate of the masses, then surely 
draperies are the opiate of painters".  Loved his discussion of the late 
work of Goya.

I haven't seen the program.  I happened to read a bit about it recently, 
just what I could find on the web, but I didn't really dig in.  Put it 
off to later then lost the link.  I think it is pretty interesting 
though.  I had been trying turn up anything I could on the subject of 
Vermeer, and/or the Dutch painting of his time, and mirrors, in the hope 
that I could make some connections vis-a-vis Rene Bui's entry in POVCOMP.

   Yes, I also tried that with the crackle pattern, but without much
success... so I didn't use it for that image. But after you mentioned
it, I played with the metric of the crackle and it looks now a bit more
credible, so I included it on the last version.

   Yes, you are right... only with 2 different colorations it looks much
better now. And it was not that hard without consuming much additional
memory: on the mesh include generated by POVTree, I changed the
placement of the textures statement from inside the FOLIAGE object to
the object instance on the TREE union, and created another union TREE2
with a different texture.

   Thanks!

   The problem is my imagination... for that kind of touch it's really
poor... but let me see what I can do. :)

Thanks to all for the criticism! I've corrected some of the flaws
mentioned and will be working on the rest for the final version, ASAP.

I'm sending a test without radiosity nor focal blur, because with
area_light is taking now *very long* to render (10 hours so far, and it
didn't complete half of the image).

Some comments:
1.- Thanks God I was sit in my chair when I saw it.
2.- My wife said "... and?"; "It's 3D" I answered; "Whoao..."
3.- My little daughter couldn't believe the trees and the cars were done 
on a computer.
4.- I'm very proud of you. Great job Jaime.
5.- Sure it's redundant but "Stop posting photographsssssss" ;-)

... keep it up

Wow that's even much better :-)
I don't know if it is the no radiosity option but wet can see a lot more
details.
When I compare our 2 images, it's definitely the last which is a photo ;-)

Woodcuts --> Raytracing ??? :-)

I’ve got a book of Dürer prints although I’ve not looked at it in ages.
Shame on me!

That renowned son of Jamaica has a garden in NY? Fame!

It generally takes mothers little helpers (if your mother is Jamaican) to
get me in that state:-) Seriously tho’ Seeing things through a child’s eye
is one of the wonders of “the” artist. Putting the view on canvas (?) is
another.

Missed that.

It is amazing!!
Just two little corrections... :)
1) There is no speed limit on this high way.
2) It is not realistic because it can not be that the white markings on the road
have faded spots. at least not in Germany...:)

When I teach my students some CG and ray tracing, I always show them the work
here.
