...or Jean Baudrillard would have said: "simulation of a simulation"

Well, at least a good exercise and a nice way to beat the time at
a rainy day. The original image is the cover art of the old bible for
graphics programmers:

 "Dutch Interior, after Vermeer", 1987
 by J. Wallace, M. Cohan, and D. Greenberg, Cornell University

I guess at this time they used some mainframe for doing the render.
The POV-Version is only lit with radiosity and took about 7h with
a 800MHz Athlon. I think the lighting in this scene looks even more
*real* than the original.
A version with higher error_bound setting was closer to the original
image and took only 1h. Not so bad.

The POV scene was done with a lot of guessing, assuming, trial and
error to recreate the 3d scene from the 2D-image. Far away from
beeing perfect but this was the best I could do without loosing my
patience.

The paintings on the wall are still a problem. I guessed they where
both by Rembrandt but it seems that this is only true for the second
(the bigger one). In the original version this image looks a little size
distorted (like they have used a wrong aspect ratio for the image
map) but I think it is the same painting.
Does anybody recognize the first one?
I have simply used another Rembrandt for the moment.

If finally some of  you would like to copy the original Vermeer painting:

Nice job so far.

Oops, guess I didn't make my point clear.
I did not try to copy the original painting. I just tried to reproduce the
CG image from the Cornell University. And they have used a painting
as you can see on the book cover. It's just the copy of a copy of a...

so long

P.S. for the copy of the Vermeer painting lit only with radiosity I will wait
'till I own a 5GHz machine or something like that. And even then it will
be quite contemplative...

Hello,
First of all I find it a very nice picture. Although there already exist
raytraced "copies" of some of Vermeer's paintings, using heavy (and
expensive) modeling and raytracing programs, this picture illustrates
how Povray can be used to obtain similar results, perhaps at the cost of
much manual modeling and programming.
As to the real dimensions of Vermeer's rooms a lot of work has be done.
Recently appeared a very interesting book "Vermeer's Camera" written by
Philip Steadman.

I don't recognise the first one, but maybe you should try and google up 
some portraits from Frans (Hals a dutch 17th century painter).
His style matches the composition/ lighting of the painting, allthough 
that could be said for more contemporary(?) artists.
If it is in fact not by Frans Hals, you can probably find one that comes 
closer than the one you use now ;-).

I find http://www.kfki.hu/~arthp/ a helpful for pre-19th century art 
resource.

Good work so far, I always like the CG remakes of 17 century masters [ 
And it gives us dutch folks something to be chauvinist about :-) ]
I think the light from the otside should be higher up compared to the 
originals?
Are you planning to stop at reproducing the 1987 render? I would love to 
  see you take it further and demonstrate how much difference 15 years 
of technological preogress makes.

I have also thought about Frans Hals - and well,  I'm not from the low
lands, but nevertheless I do know some of your famous artists ;-)

Hmm, I'm currently working on an "Italian Room" and the main reason
for doing the Vermeer copy  was to have something simple to play with
the radiosity settings for an indoor scene - but also does render fairly fast
(at least for a preview without AA).

But there is a funny detail in the Vermeer painting: the womans face,
as reflected in the mirror does not match to the direction she looks, the
reflected one looks much more to the right. I'm sure this is intended by
Vermeer and I think this could be simulated by the use of the no_image
and no_reflection keywords with POV. To reproduce this should be some
fun and maybe I will give it a try some day.
