I'm feeling a little depressed about my lack of talent for producing
cool things with POV-Ray. I'd love to be in the POVComp, but I don't
have anything nearly cool enough.
I made this. It's unfinished. (I plan to add more different glasses.)
Please say nice things.
(Yes, the glass *is* supposed to be slightly tinted different colours.
I'm not entirely sure I got the lighting right, actually...)
All objects 100% CSG. The tallest glass is [supposed to be] just short
of 20cm tall. The scene uses photon mapping (with spacing=exp(-3)*cm),
which gives about 85MB of photon map. I haven't tried higher yet. (I
might actually cheat and finish this at work on that spare server next
to my desk (!!!) with 2GB of RAM (!?!?!!!!?!! *faint*) in it...)

PS. The right-hand glass is actually tinted green. Not that you can
tell. I don't think the glass is actually thick enough.
PPS. All glasses modelled using actual measurements from real physical
glasses. The glass on the right did look *very* wrong - until I realised
that the *diammeter* should be 65mm, not the *radius*. Doh!

Perhaps reconsider what you think of as "cool". There is a huge premium
on these groups accorded to technical ground-breaking. But I suspect
that there are a few artists that have been content to till already
broken ground and are going to start producing fruit.

Completing pictures entirely with csg primitives is a very satisfying
accomplishment and potentially capable of powerful results. To me it is
akin to classic burin engraving in the world of printmaking.

Well art is subjective and while I want to say nice things about your
picture for me all that juicy, glossy green gets in the way. But I think
the basic idea has a lot of potential. I took the liberty of playing
with the color and cropping just for fun. Didn't mean to offend. A
composition of three glasses has nearly infinite possibilities after all.

Well, it's just that this is the very first image I've ever posted that
looks like a real-world object. It actually looks like something. Most
of my other images have been just vague patterns and so forth...

That is indeed impressive.

I'm not sure that the floor will be the same in the final version. While
it does look lovely, I was thinking maybe dappled grey could look good
as well... (and your offering isn't too bad either. A tad too monochrome
for me, but I could make just the floor that colour perhaps...)
I had im my head a final image involving a few mirrors and some
striplights (a bit like a display case in a shop), but we'll see how far
I actually get...

I agree, but I can't completely explain why. While, I don't think using a
modeller is cheating (in any way), you also give up some things when you use
a modeller, and you often have to suffer with weird artifacts that wouldn't
be there without the "fake" surface normals (fake, meaning that normals are
not the same as a real curved surface in CSG).
There's something intriguing to me about the purity of POV-Ray SDL. Maybe
it's because I'm a computer programmer by profession. IMHO, creating a
fantastic scene in CSG without including any meshes is quite an
accomplishment. Ditto for procedural textures as opposed to photographic
textures.

For me, it's quite simple.
If it's 100% CSG, than you can look as close as you like, from any angle
you like, and it will look correct. No triangles where there should be
smooth curves.
Same thing with procedural textures; no pixels anywhere. Plus procedural
textures are truely 3D, whereas [most] bitmapped textures are only 2D...

Well, you have picked one of the hardest things to model. Glass is
notoriously difficult. Just think of all those painters of long ago trying
to get it right. Light is so heavy :-}
I also think that the eye deceives the brain in RL (T) and we see what we
expect to see. So when looking at a rendering the colours can seem
exaggerated or unrealistic. Just keep plugging away and you will become one
of the experts.
That aside, I think your glass is a bit too thick (if you want to make fine
glass) but overall the modelling looks good. The Lights, IMO, are a bit
close to the glassware, going by the shadows.

Did you do a SOR to make the glasses?

Nope; just cylinders, cones and torii. And lots of CSG...

[...] with me as your grid; y'all can see me now cuz you don't see with
your eye, your percieve with your mind [...]

The two glasses on the left are supposed to be fairly thick. (The
real-world models they're based on are fairly thick.) As for the right
hand one... yeah, that probably should be thinner... especially that lip...
And the lights... There are 3 of them, one on either side, and one above
and behind. I think this is what's casting the extreme forward shadows.
I'm still not entirely sure the lighting is correct... I always struggle
with it. Oh well!
