Exactly.
Here is the relief (on the top of portal) which we'd like to mimic:

That's probably a good idea.  I made some tests with generating a
heightfield from the photograph on

http://www.milton.com/praha2002/im000163.jpg

here is the result.  It surely does not look very good which is of course
partly because the photo is not that good for this purpose.  What helps is
that shading in our case is somewhat similar to the photo although with
more shallow lighting - otherwise you would not even recognize the rough
geometry.

Yeh, we need more detailed photo(s). So if there is anybody who lives
nearby the cathedral could you take some pictures ?  :)

As far as I know Poser has also horse object(s). Could anybody who
has Poser try to make some kind of horseman relief using technique
described in this thread?

That relief technique looks really good! I have Poser 3, with the horse and
everything, but since there is no way to do clothing, it could prove a bit
difficult? Or are the figures mostly nude? I'll se what I can cook up in the
weekend, shout out if you find some better reference pictures.

My newsreader broke the first link between "top." and "half.jpg" but 
strangely enough, I got the image anyway, just in even higher 
resolution. The same works for the other image: drop the "half." and you 
get the image in double res.

Thank for the links, btw.

So that's what it looks like! :) Thanks a bunch!

Ain't you a tricky one ;) Tak!

If the final resolution are to be 6000x8000 the triangle will then be
about 1050pixels wide, or? I just need a feeling of how detailed it has
to be.

I've attatched my first test render, and looking at the new reference
pictures I think I can get away with it if I do some helmets in Wings.
And perhaps a sword, and some nice outfits and armor and.. :) Hmm.. The
casual Poser 3 man might look better because he has a t-shirt on.. This
is fun! *running away playing more*

I get the triangle to be close to 25% of the image width, at its widest, 
which is 1500 pixel. I don't have the exact size of the triangle, as it 
is going to be the last part, that I model, unfortunately, due to the 
way I'm working through the building. The acute angles a going to be 
close to 27 deg, though.

Looking very promising.

Gena, exactly how did you generate that second image?
