Wow! Very impressive!
I think it's the best architectual CG object I've ever seen.
Are you still working on it? I'd like to add it to my changes and
render the scene (hopefully this week).

Well, thank you, but I hope not. I have done at least two other churches 
with a lot more precision and detail :)

I have some minor adjustments to do, and I would like to try and fit it 
into the scene as closely to the painting as possible. Have you done any 
changes to the camera since your last posted version?

It really is incredible.  I admire you patience and good eye
for proportion and detail.

Yeh, I know. But I like this one more, I don't know why :)
What do you think about textures? I could suggest you some
image maps for dome and walls. I know that you are POV-Ray
purist and don't like any image maps :) but I think image maps
will look more real-life than procedural textures.

No.

I was hoping I could leave the texturing to you, because I can't get 
anything to look right with assumed_gamma 1. I'm going to clean up my 
texture use to as few as possible, and declare them all at the beginning 
of the file, so it should be easy to change them.

Good, the I will take the latest version and try and fit the model to 
the painting, before I post it.

Not at all, and that's an incredible model you've created!
Sadly I've not been able to do much work on my part lately, been a busy
week in RL(TM). What I've done is created some objects (helmet, sword,
some cloth) in Wings3D and added them to the figures in Poser, in
addition to repose the things. I've also done what Gena suggested and
included all the figures in the scene, thus only produsing one
height_field. I think I'm also going to do some manual editing to the
image to increase the details in some places.

That reminds me my very old picture in traditional media:

http://propro.ru/go/gallery/images/knights.jpg

The following image is my attempt (which lasts two years :)
to do the same on computer. And the second image is a
heightfield created from the first image.

I would like to put a dummy height_field in in my model, so when yours 
is ready, it should just be a matter of replacing my dummy file with it, 
and it will be in place on the cathedral. I hope.

To do that, I need to know what file type you are using, and what you a 
going to call the height_field file.

I'd like to use PNG if it's okay, and the filename can be something like
"cathedral_relief.png" all lowercase. Or use anything you like, it
wouldn't matter to me.
What resolution and aspect ratio are you going to use? Are you going to
use CSG to cut out a triangle of the height_field? If you could give me
a copy of the dummy image, I'll adapt the aspect ratio from that.

PNG is fine. It doesn't really matter, as long as we agree.

Yes, I'm cutting the hf. Here is the code:


#declare FcdPedimentTympanum=difference {
    object {
       height_field {png "cathedral_relief.png" smooth }
       scale <700, 20, 171>
       rotate <-90, 0, 0>
       translate <-350, 0, 0>
    }
    plane {-y, 0 rotate <0, 0,  26> translate <-350, 0, 0> }
    plane {-y, 0 rotate <0, 0, -26> translate < 350, 0, 0> }
    plane {-z, 0 translate <0, 0, 1000> }
}

For some reason, I don't quite understand, my dummy hf projected out 
very far behind the facade, that's why I cut with the -z-plane.
