Looks good, are the textures all image maps?  How did you generate them? 
  I assume you use UV-mapping generated in Wings.  I have not yet 
figured out how to do this (guess i need to have a look at the manual 
after all - something i have not bothered to do until now...)

Nicely done, Jaime.

The plants add to it very well, but I wonder if it might make more sense to
have them grow better nearer the archways and less toward the interior?
Except it looks like daylight, or skylight, might be inward of there too
judging by the shadowy parts in front of the inside pillars. Unless that's
due to a unseen wall reflecting light back outward.

The texturing is realistic. Just that some pillars don't seem correct
because of the mortar lines disappearing, even in the blurry foreground I
thought it might show more of the darkened lines. Perhaps something to do
with either texturing, radiosity, normals, focal blur... or all combined?

Trying it as wallpaper here, it looks great even though stretched to
1600X1200.

   Yes, all the textures are one image map, found with google at

     http://www.fromthedirt.com/textures/concrete.jpg

    but I've "proceduralized" it with several turbulent warps to avoid 
pixelization. On the floor it is used with higher turbulence, and on the 
walls it uses two layers with little but different turbulence values.

   No, I'm just on the same situation... but I don't even know how UV 
mapping works in POV-Ray.

   I just used the texturing capability of Wings3D to assign different 
materials to groups of faces, so I can rotate them later with POV to 
face the correct direction.

   Also, I assigned different materials to the fictitious blocks/tiles, 
so the texturing is not continuous from tile to tile. In total, the set 
of column+arch uses 12 different textures, 4 for each direction. The 
mesh is contained on a macro to obtain a different texturing on each copy.

   Yes, I later noticed it... and it was not intentional, just the 
random seed used for the placement.

   Yes, there are some elements at the right, out of camera. But it's 
also due to the stronger bounce of direct sun, on the floor at the left 
side.

   No, it's just that I badly modeled one of the sides of the column on 
Wings3D, and since there are many copies randomly rotated, some times it 
appears this effect. I must have used too little depth on the mortar 
extrusion...

   Thanks! I will do the final version bigger... :)

Ah, so the brick structure is not actually painted in the image map but 
results from different textures assigned to the different parts of the 
column?

   Yes, see the attached Wings3D screenshot. It's a bit tedious, but not 
more than doing it with CSG.

And surely faster to render...

I just did some tries with the UV-Mapping feature of Wings and it seems 
to work relatively well - you can probably get similar results this way 
without subdividing your models like you did but you will have to paint 
a high resolution map of course.  The bad thing (and a general problem 
about Wings) is that it gets really slow once you deal with models of 
more than a few hundred faces.

Oh, oh, I worked there [for a moment] :) (couldn't resist, sorry ;)

Greate image, very photorealistic indeed

Beautiful and very realistic. Congratulations!

Are you going to post the code in your website?

Good job!

Fernando
