Here's a little pic I made.
- Terragen sky. Actually, it's a terragen-made panorama linked to the sun
position.
- isosurface terrain (ridged multifractal)
- xfrog plants : for those who don't know it, xfrog can be described as
Poser for plants, with animation and modelling abilities.
(http://www.xfrog.com, fully-functional 30-day trial version available).
Some of the plants (the tree, the dandelion) are derived from the models
bundled with the software and I made others (imaginary ones...). Norbert
Kern's IRTC winner "warm up" used a lot of xfrog trees. Here there are
around 17000 plants.
- 2cv car by De Espona, with some parts remodelled in Rhino. Rust texture
borrowed from HE Day.
- low quality radiosity (runs quite fast in fact, 8 hours at 1200*1600 on my
P733).
The image was rendered with assumed_gamma = 1. The gamma and contrast were
adjusted by post-processing. It could use more contrast actually. I couldn't
get rid of that painterly look but it's not so bad after all.

Impressive! (As always...)
On one side, I always see the technical background you probably
have in order to create such images.
On the other side, I see the imagination you probably have
in order to come up with such images.
You've definitely got a good combination there...

Absolutely stunning.
I'd suggest put some focal blur on it and add a little roughness to the tree
bark, other than that it looks like a photo!
Nice one :)

Well, I was skeptical at first, but I simulated focal blur in
Photoshop LE, and I have to agree with you. If a SMALLl amount of blur
is applied to the objects farther away than the tree, it looks good.

Neat.
The small bush in the foreground looks a bit like a small scale version of
the tree.
Are all plants made with xfrog?

i suppose this is a scaled version then? If not i wonder what aa settings
you used, the more distant trees look nicely smoothed.
Higher quality radiosity settings would probably improve the sense of
depth between the plants.

Since you opened the topic of needing contrast, and trying to lose the
"painterly effect", I toyed with your image in Photoshop LE, for a
little while, trying to make it more photographic looking.
In my opinion, the rusty vehicle texture needs more color saturation.
This was one of the best tweaks I found for this image. Perhaps there
is too much radiosity, or too high of an ambient level specified in
the rust texture? I also selectively darkened the shadow tones on the
right side of the vehicle, without also darkening the highlights or
midtones.
The foreground has a subtle haze clouding it. I manipulated the darker
tones of the foreground to he slightly darker. This got rid of a lot
of the hazey look. I left the haze in the background, because it seems
appropriate there.
If there really is some sort of haze/fog/media/atmosphere type of
effect coded into the scene, it need to only be applied to the
background area beyond the tree. If there are no atmospheric effects
used in the scene file, then perhaps the ambient level/ radiosity
level needs to be reduced in the foreground? Perhaps your textures and
colors need to be tweaked for a bit more color saturation in the
foreground?
All those haze comments are assuming that the scene was meant to have
a warm, late-afternoon sunlight effect, with somewhat warmer and
bolder colors and contrast.
I increased the color saturation of the blue and cyan tones in the
sky. Either try more saturated colors in your sky description, or
perhaps use a less hazey sky?
I also darkened the shadow areas of the tree leaves, increased the
color saturation of the green leaves, and brightened the highlights of
the green leaves.
This was just done in a few minutes in Photoshop LE, and is not
intended to be my best effort, but a simple exploration of what might
be tweaked.
I hope you appreciate the comments, and I hope you post more of your
excellent images to the newsgroup in the near future. I've been
missing your contributions here.

I've attached two more quick Photoshop variations. The first one is
Not_4_Sale_fb.jpg:
This image simulates focal blur by selectively applying gaussian blur
to the areas behind the tree. I used an amount of "1" for the
gaussian blur. The effect is somewhat subtle. Higher amounts didn't
look like focal blur, but simply a poorly-focused image.
The second image is Not_4_Sale_Fog.jpg:
This is a simulation of fog, by applying a huge amount of gaussian
blur to the background areas behind the tree. I selected those areas
with Photoshop's lasso tool, and feathered the selection by 45 pixels.
The gaussian blur amount was set to "48", which is a LOT of blur.
These are just quick explorations what might be done, either within
POV-Ray itself, or in a post-process. I think the results are
interesting.
Oh, I should mention that Gilles himself thought it would be good to
post some of my comments here, as I had earlier sent him only private
emails. He thought that some of the information might be useful to the
rest of the newsgroup.

Now that is one masterpiece!! Your amount of plants are higher than I would
dare, though. You mean, you're using 17000 unique meshes? That takes a lot
of memory. I would have sticked to 20, perhaps 30 different meshes and
reused them... Even in my wildest fantasy.

Hugo

In mine too :-) I wonder when I could have produced 17000 different meshes,
and where I could have stored them... No, it's just 10 or so different
meshes replicated thousands of times.

Hmm, I guess I'm not proficient yet with xfrog.

Yes. The tree and the dandelion were ready-made models (I just changed the
leaves on the trees). The others were created from scratch.

It's a scaled version of a 1200*1600, with a slight "accentuation"
filtering. I remember seeing recently interesting tips about aa somewhere in
this ng but I couldn't find them.
> Higher quality radiosity settings would probably improve the sense of

Possibly. The truth is that I'm already in the 400 Mb range of RAM use and
that higher rad settings would certainly cause problems.

Wow great picture as always! One thing, I'm sure this is a result of scaling
down the image from 1200*1600 but incase it isn't, your tree has a number of
floating leaves, that is leaves that don't seem to be atached to anything,
though I'm sure in the full sized image they are just attached to very small
twigs.

The blurred one looks a bit strange to me. To get that amount of blur at
that position in a photo, you'd have to use a big telelens. Then the
forground would also be blurred. Also the 'perspective' doesn't match with
a telephoto.

No you're right. There are some tiny twigs but looking closer I can see now
that some leaves actually float in the air. Weird. I'll have to check the
model.

Ingo is right in fact, the angle is 90°.
camera { location <0, 1, -9>
direction z*1
sky y
up y
right x*image_width/image_height
look_at <0,2.5,0>
translate -x
}
I did play with smaller angles but I wanted the upper sky to show up.

the default angle:
~67.380 (direction_length=0.5*right_length/tan(angle/2))
in this image that would be the vertical angle.

I know. Else I would have complained about the lack of blurr on the

90° seems to be the vertical angle, or so it says in the const.inc file.
Not that I'm sure of what it means anyway, which is why I keep using
"direction" instead...

Lazy as I am I didn't calulate anything. In the default situation with a
aspect ratio 4/3 and a direction length of 1 the angle is ~67°. In Gilles
images the only difference is that the aspect ratio is 3/4. As if you
rotate your 35mm camera 90°. The horizontal angle becomes the vertical
angle. The diagonal angle stays the same.

Yeah, because you specified up right and direction, that will determine the
angle. In this case direction is the same length as up, which means you'll have
a 90 degree vertical angle (i.e. both the top and bottom of the view fustrum
will be at 45 degrees from the direction, so 90 degrees in total).
This means your horizontal view angle will be
2*degrees(atan2(image_width/image_height,1))
but now I'm just trying to blind you all with maths :)

truly inspiring, gilles. i don't think i've ever seen anybody
with such a great combined talent in art AND programming.

I rendered this xfrog tree with high resolution.
You can see some limitations of the standard xfrog trees, but no leaf is
floating in the air.

That really does not look good, are those lines produced by broken
image_map textures? I think the 'maketree approach' is probably better
for modelling leaves than using partly transparent textures, despite
higher triangle counts it could even be faster.

Christoph , you are right. I do not like the leafes of the standard Xfrog
trees too.
But you can also define leafes out of triangles within Xfrog.
Therefore you can make the best conifers with this program.
Or can you show me a better mesh pine?

High!
Must be somewhere in southern Afghanistan - once a top travel destination among
hippie 2CV enthusiasts, probably near the Herat-Kandahar highway between
Daulatabad and Girishk! Are the trees in fact tamarisks?
See you in Khyberspace!

I have not worked much on coniferous trees, but the growth of trunk and
twigs in this one is far from being realistic.

Actually I beg to differ, take a look at the blown up images attached. Again
I think this is a result of sizing the image down from its original
resolution. The small twigs get so small, smaller than a pixel, that they
are left out entirely.

In fact I'm really not sure of that... These are 5th level branches and I
couldn't see them at very high res. Also I had changed the leaf model and
some bits of the tree structure. Now I've stopped the growth at the 4th
level and it looks much better (see pic below).

In fact there are several ways to define leaves in xfrog. One is a simple
square with a image_map, but you can also have (almost) complete control on
the shape of the leaf (using a spline) , its texture and curvature. I'm
still new at this though.
