Looking good so far!

Two things to mention: the portal on the right side seems to be more a
cornered portal than a curved one ;-) and the texture of the floor looks a
little too flat to me. maybe adding normals or using isosurface instead?

Thomas, this is looking very good. Bicycle aside, I can see this as a tower
in the Italian hills.

I do agree with the comment on the floor looking flat. Is this supposed to
be a tiled floor or one that is painted?

The frescoes look good. Is this an image map created by you?

I look forward to seeing more.

Well I sense that there is a lot more here than meets the eye.  It is a 
very powerful image as is and I sense a lot of (cerebral) potential in it.

It is in one sense a variation on your "Ice Cometh" picture in that you 
use the tension of having a background scene framed and contexted by 
foreground architecture. It is also an extension of your Copernicus 
picture with it's sense of mysterious and underlaying geometries.

Yes indeed, Jim. All you say is true, and certainly not always consciously
attained. It is one of my fastest scenes (a couple of days) and I believe
that I am not going to modify very much, despite some shortcomings, as has
been stated by Roman and Tim. The deeper reason is for this isthat the scene
should be far from realistic and expressing a state of consciousness
familiar in dreams. There is something of de Chirico in it, although the
direct inspirator was a painting by Jos Janssens I saw in 1999, and of which
I had made a little sketch. It has stayed dormant for six years.

The frescos were provided by Adriano Del Fabbro with his Cloister.3ds
(1997), which can be found at the 3D Cafe. Indeed, the portal to the right
is angular as I intended it to be. Bicycle and lizzard come from the Taschen
object collection. The bicycle imposed itself on me as soon as the portal
took shape. In an otherwise empty (of human presence) environment, it
suggests somebody is there, near, and yet out of reach; familiar and yet
slightly menacing.

Thank you Roman!
I agree with your comments. The doorway to the right was kept intentionally
angular. However, I think now that I shall change that, as there are anyway
a few small corrections to make there.
The floor I am still unsure about. I am experimenting with a few options. I
want to keep it as much as possible like in this version.

Thank you , Tim!
Yes, the setting is definitely Italy. I googled a photograph from Tuscany
that exactly answered my needs [and took note of the photographer's name!]
The floor needs attention. It is tiled and I am currently experimenting with
a few options. Stay tuned. As said to Roman, I want to keep it as much as
possible similar to the present one
About the frescoes: see my answer to Jim Charter. The images are not very
high resolution, so you cannot zoom in too much, but as a background or a
middleground, they are quite effective. I don't know where they originally
come from. I suspect that they are Italian too.

Very nice image Thomas.

Some suggestions:
The floor looks too new a bit too industrial for such a building. You are an 
expert with layered textures, than you can do very better.
The image map with the dance is  skeleton seems to ben enlarged on the X 
axis.

Thank you Rémy!
Well, the floor *is*  (I should say *was*, because I have changed it) a
layered texture, but it is too smooth. I have changed it now, by adding a
normal to the tiles, but in doing that I could not keep the layered
textures, so I changed to simpler ones. See the next version soon.
Concerning the image map, yes you are correct... I had a problem with uv
mapping it on the cylinder portion (Poseray) where it seemed stretched out
originally. This way I could correct it more or less. What you also might
see here, is some deformation at the edge of the camera. It is wide angle.

A new version of the Portal.
Two features have been added; two features have been changed! Find the
differences :-)

P.S.
Don't mind the right-hand frescoe's down-turning edge. has been corrected
since.

I may try a totally different floor, but I hesitate...

I hate to be the bearer of bad news, but it still looks like airport 
carpet to me. I think it's partially the color .. getting such a blue 
when all the other stone is beige is a little surprising though I 
imagine there are thousands of examples IRL. I'd prefer to see 
beige/brown/terracotta/burgundy .. but then maybe it's not even that .. 
but it does feel like airport-carpet to me :)

Other than the floor (and the slight x-distortion on the fresco) I love 
this picture .. has the warmth and life of an oil painting, but entirely 
generated in a computer! Well done!

Cheers!

I have to agree with Rick that the color of the floor doesn't fit very good
to the rest of the image. but i like it anyways. i even think it's looking
better this way instead of having everything in one tone.

But there is still an other thing about that floor that i dislike. i saw it
already at the first example but didn't say it because i think it is
difficult to explain due my limitations of the english language. but i'll
give it a try.

The floor has a little rim (or step?) at the right side. But the texture
doesn't take care of that. its just projected over the shape. know what i
mean? that somehow doesn't please my eyes. maybe you could add a curbstone?

I hope you understand what i want to say ;-)

Greetings Roman

Another version.
Rémy, I have scaled the image map in the u-direction somewhat more for a
better fit. The consequence is that the scene has shifted.
Another floor tile is shown here.

Well... perhaps they used airport carpet here !! ;-)
However, I agree with you, and this morning I was also thinking about
terracotta colours indeed. See the new version again

Floor and distortion have been corrected (?) still more....

Yes, I know what you mean. It is the effect of the texture. Simple to mend:
I shall add a curbstone.

on the step... I second the idea that the step on the right side at the

Furthermore, i still believe there's something not quite right at the

straight. Is it an illusion?

Once again, great job!

Thank you! Thank you!
The floor is taking quite a lot of comments, so I shall have to work on it.
I have decided now to throw out the tiles and go on with a rougher floor.
Still experimenting though...
You are right about the lower righthand corner. I don't know how to solve
this well. The wall is a cylindrical mesh, and it has been subdivided
several times, so I am a bit at a loss why it still seems straight.
Especially, as in Poseray, it looks smoothly curved. Puzzling. Have to go
back to the original I guess.

Well well better Thomas.
The fresco is nice now. In the last version, there was the following way to 
reduce the deformation on the x axis is to decrease the image map itself 
using a transformation. In fact there surely no way to correct the camera 
deformation, but the important thing is to satisfy our human vision. In the 
Parthenon, the columns are bended or curved, isnt'it? The floor would be 
better with terra cotta tiles.

Thank you Rémy!
Yes the fresco is better. It was a matter of multiplying the u-scale some
more. With some trial and error I thought this was the best proportion.
I have now also corrected the apparent straight wall in the lower righthand
corner. I am learning to work with meshes every day! The culprit was the
corridor opening, as I had not provided a solid basis to it when opening the
cylinder.
For the floor: yes, I am working on a terracotta coloured one. No tiles this
time, but a rougher textured surface.

Thomas
