1° Wow!
2° How are the chains attached to the wall & boards?
3° I don't like the pictureframe.

Some more:
I think your image is really superb, not technically per se, but for its
content. I would consider this Art (with a capital A ;)). At first the
lines on the background bothered me but that was before I saw the whole
image. After that the disturbance became more or less functional, as
with some other (disturbing) things (the chains?).

Don't know what it's all about but that curtain and it's shadow is good.  I like
the chalked lines too, even if they are perfected lines.  The fuschia (?) paper
on the wall is an oddity more than anything else.  Don't know if my observation
is right about the overall lack of contrast or not but it gives it a look of
being a print of some kind.

Really great.. simple and neat... like it....

...but (it seems to be a 'but' every time...)
The curtain is something strange : the bottom should be ondulated (?) and the wire
(?, the 'schnarflux' ;-)) which hold it is to straight (?)... should have some
angle...

But I say it once more : it's a great pic...

I don't get it but then again it is art. Nice work. What's with the lone
sheet on the wall?
Suggestions:
The wood frame looks like it's cut from a solid block. Individually
texture the pieces.
How do the chains attach? Make some little hooks or something.

I was very reluctant to post this image but you guys
(I include not just the responders, but the entire
group) proved me wrong.

I was very happy with the 'look' of the curtain.
spatch is an amazing, albeit frozen in time, program.

Technically I had a patch 'issue'.
The use of CSG difference to create
the curtain's loop holes.
To quote from the docs:
"They [Finite Patch Primitives] may be combined
 in CSG union but cannot be use in other types of CSG."
 I know this has been discussed before but it
 does bother me a bit.

My inability to image map a patch resulted
in a kinda weird blueish piece of paper just hanging
there. No UV mapping, I used standard pov.

I also had difficulty, if you look, merging
a cone and a sphere to make the chalk 'mound'.

The wallpaper is a result of not wanting a plain
background and my love of grids.

The chains should be attached to the wall and shelves
with eye-hooks which I did not model.
What bothers me is the lack of something holding
the curtain tie. As well as the general unreality
of the curtains edges.


Remco: thank you very much!

Bob: You have a very discerning eye. Your comment
about it looking like a print makes me think
about doing an image with this in mind.
I wonder if the lack of contrast is partially
a result of the images use of pale colors.
I posted a version that does not have a
glaze on the vase

 FreddyD: Ich danke Ihnen vielmals.I try to learn the wonderful
 German language without much success.


The 'Art' look of this image is no doubt partially a result
of my art school (SFAI 1988 BA) training. I don't know if
I would go so far as to call this Art but I do believe
that it is possible to create Art with PovRay.
(This is saying alot for me, an admitted pretentious
 art fop.)

Artistically this image is 'about' the idea of
Platonic solids. The vase (as woman) and it's
2D representation on the chalk board. It's
working title was "Blackboard".


The genesis of this image was Martin Vilcans' "Balls" entry
in the Physics and Math topic of IRTC and his adroit
creation of chalklines.

	If the patch (or mesh...) is flat (as is the case for your
curtain), POV can't distinguish the inside from the outside,
so CSG intersection and differences are impossible. But you
can always cut holes in a patch object with clipped_by...
	If the patch is a closed solid, MegaPOV is able to do CSG
with it (albeit probably with a warning saying that it
doesn't work, although it does. There was such a warning in
uvpov, I don't know if it was removed)

The image reminded me of several images by modern (not-so-much-anymore)
painters, a.o. like Jasper Johns. Also it reminded me of the story of
the two (ancient) Greek painters who had a little competition about who
could make the most realistic painting. The first painted a bowl of
grapes whcih attracted birds. The other covered his paintning by a
curtain. When the first painter tried to llok what was behind the
curtain he found that the curtain itself was painted. While the first
could fool his animals friends the second could fool his human rival ;)
Last the image has something 'Escheresque' with the curtains shadows
showing below the frame while the curtain itself stops inside the frame.
This gave me the idea that the chains had no way of attachment because
they might have been painted as well... and so on and so on...

Hey David,

The wood frame is modeled after a little (about 10"x8")
blackboard I have. I spent so much annoying time adjusting
the clipped_by pieces that I neglected the texture,
I admit this. I'm no Sir Uncle Ken when it comes to textures.

object {Peter_Warren translate <on_high_horse>}

Five years ago I had never used a computer and
pretty much avoided them.
Now when I show my stuff to my art friends it's like,
"Dude, that is awesome, you are such the computer god"
or "Your the Bomb Peter, I can't even get my word processor
to work."
Of course, most everyone here knows more about computers
and pov than I do.

In school all my professors came from varying backgrounds,
some were PAF's (pretentious art fops) like myself but
many were just really into detailing their cars (or what-
ever) and fell into art on accident.

So when you say "I don't get it but then again it is art".
I don't know what that means. I mean, I know what you mean
but I don't think it is what you are trying to say.
If you say, "I don't know when Goya painted
'Executions of the Third of May,1808'"  that is one thing.
If you say, "I saw an 'Art' show at such and such a
museum/gallery and my five year brother could make better
'Art'." that is another.

I've seen your stuff. You make images. You make good images.
Many artists make images. If you find yourself making images
in five, ten, fifteen years from now you could probably
call yourself an artist without much argument. At least not from
me.

Actually when I realized how you made "Guess
how this was made" I thought of a
collaboration piece we could do together.


Anyways,
thanks for the critic, as usual,

I just saw your post and I am speechless (There is a first
time for everything.)
Before I post this I will go over your message in detail.
-------------
Your mention of Jasper Johns (perhaps best know for his
recent appearance on The Simpson's),and, IMHO, my country's
greatest living painter, is both a testament to your artistic
sensibility and a proof that my image(s) is(are) a success.

For this I thank you. I would be saddened if you were
ever in my neighborhood (the University District of Seattle
Washington, USA) and we did not share a word or two.

Such a well told tale you tell of these Greek painters.
There is a similar story about Michelangelo, a fish and
a staircase. But it is late.

I have "issues" with Escher. Another time, perhaps.

I don't know how to help you really about povray patches.. but I tried to give you my
first impressions on your (_really_ beautiful) pic...

I just mean I don't know what the point of it is. I mean, is it supposed
to create an emotion, is it modelled after something you have seen, is
there some significance to the components? But I am also saying that
doesn't really matter to me because it's art and that's one of the great
things about art is everyone has their own tastes and interpretations.

	Yes but how is CURTAIN defined? From what you said, I
believe it was done in spatch and therefore it is made of
bezier patches which can't be differenced... Try this
instead:
object {
  CURTAIN rotate<90,180,180> scale 1 translate <1,2,0>
  clipped_by {
    union {
      cylinder ...
    }
  }
}

> >PS: nice pic
> Thanks.

	You're welcome

		Jerome

PS: After reading your original post again, it seems I
didn't get your problem... Were you saying you couldn't cut
the holes in the curtain (wich is the object of the section
of manual you quote) or you couldn't texture it to your
satisfaction because of the way image_maps work?

Well, maybe it can't be differenced from an object, but objects can be
differenced from it, ie, you can cut holes in it and stuff. I did it
with my Black Seas Barracuda sails and they're made in sPatch. POV
complains about it but it works just fine.
