Image wine_glass-surreal.jpg is a trick photo that was posted in the
POV-Ray Facebook groups.  A reverse image search shows that it's been
kicking around the Web since at least 2009, but I cannot identify the
original photographer.

Image wine_glass-quartered.jpg is my attempt to reproduce it with POV-Ray.

After I created this scene, I noticed a wine glass in a restaurant that
was considerably larger than the one[1] wine glass that I own.  I
decided to look up a standard or typical size for wine glasses.

Turns out there are between 18 and 35 types of wine glasses, depending
on whom you ask. To simplify things a bit, there is an ISO standard for
wine tasting glasses (boy, there is an ISO standard for *everything,*
isn't there?), but it is considerably different than the 4 wine glasses
in the last paragraph and the attached images. Who knew wine glasses
would be so complicated!

One thing is clear from the various specs I found: The glass should be
much thinner at the rim than I made it--even though I tried to reproduce
the thickness in the photograph.

[1] It was for an art project.  I'm (mostly) a non-drinker.

Have never seen this before, it is a great idea/image.

I haven't used povray for ages :-( but I really used to enjoy trying to
reproduce an image (usually photographs) in povray using only CSG/code. I like
the challenge of turning just text into an image that if it goes well could fool
someone into thinking it was a photograph.

isn't that "thin rim" thing a white + sparkling wines (and brandy) thing, not
reds?  (from one tea-total to another :-))

Both images are of high quality indeed.

I /am/ a wine drinker, but I just use a simple Duralex glass (those with 
9 facets). I still have an average wine glass which gradually thins 
towards the rim indeed, but starting from a slightly thicker base than 
in the images, towards an identical thickness at the rim.

Very nice.

Now, a bit of nit picking...
It seems that your ior for the glass is to small, and that for the wine 
to high.
In that image, the out of field environment is paramount. Try giving it 
a slightly more contrasting gradient.

Very very good idea and images.

I'm sure experienced people will recognize the glass ;)
