Hi!
I've been working on this scene for a while now, and I would like to know,
what you think about it.
Thanks go to Alf Peak for the fibonacci-pattern code, which I used in a
modified way. Seems like some thinks are remembered at the same time from
different people, as it was already part of the scene when Yooper posted his
nice Fib beads.
The scene took some 3 hours at 640x480 aa 0.3 with radiosity.

Nice scene. I think you have it down quite well (no pun intended). The technical
detail is good (is that just normal, or isosurface or something?), and the
composition is very nice.
Great use of the fibanocchi spirals!

Each piece is perfect by itself, but the overall composition (color
balance/contrast) is a bit off.

It looks nice, but not much like radiosity, because the shadows have very
constant brightness.
Maybe add some kind of wooden vehicle.

Hm, it takes a fair bit longer when I set it to use rad, so I think it does
it's job. ;-) Perhaps my other lights are to strong. I had to position one
light_source at the camera position, otherwise the details under the well's
roof wouldn't be visible.

I thought the same sometimes while making the scene. Perhaps it would give
the scene more life.

Perhaps you are right. I'm not that satisfied with it myself. Any idea, what
I could do to improve it? Should I add some more details like flower-pots or
even a market-booth - and bring some more colors in that way? Or should I
change the colors itself?
Any help would be greatly appreciated!

Thank you. Most of it are isosurfaces, some 26000 for the fibonacci pattern
and some more for the rest. The bricks are a derivate of the one's I've
posted some weeks ago. If you are intressted in something special, I'll be
glad to share the code for it (the whole scene is a bit to messy to post).
>and the

Good to know you like it. I'm not satisfied myself but I can't tell why.
Perhaps it's the lighting or the colors. I just don't know, but it has not
the same quality as "The dancing cur" IMO.
>Great use of the fibanocchi spirals!

I was glad I found the code for it, as I wanted to make some good ground
this time. The height of the stones follows a function, which is quite
flexible and I used the same function for an Iso that extends in the
background, 'cause my system could not stand more of the stones.

With radiosity, additional light sources should usually be used very
sparsely. A light source at the camera position is no good idea IMO. If
you use appropriate radiosity settings (recursion_limit >= 2) and
finishes, things should work.

I'm not happy with that light either, but I couldn't make it work. it's just
color 0.2, but makes a big difference. Recursion_limit is at 3. The rest is
set to the default values (according to your radiosity-tutorial, but I
copied the settings in the radiosity block). My idea was that the dark slate
roof absorbs all the radiosity light. Is that possible?
I didn't care much about the finishes yet. ambient is set to 0 of course
(using MegaPov 0.6a). I once tried diffuse 1 which did not much difference
to the default 0.65. Should I use different settings?

Of course it absorbs a lot of light, but there should still be a lot of
indirect light from the ground.

There is not much contrast in your picture in general for an outside
sunlight scene. Maybe increase the main light source. Decreasing
error_bound in the radiosity block should make the radiosity effect more
differentiated, but it will not affect the overall brightness.
A sample picture without the additional light sources might help.
