Wine In A Glass

I have been playing around with caustics and sort of got sidetracked by a glass of wine

Now wine in a glass is something i have been itching to learn how to do..properly. I just can't get past that sad beginners look

here is my attempt so far



Now the caustics are really bad but what i would like to learn is how to light and texture this scene so the wine look really belivable. I enclose a scene file for you all to chortle at my befuddled attempts !!

http://www.black-and-white-to-color...f/wineglass.zip

The glass is very roughly modelled from a lathed spline and then i copied to upper portion and sized it down for the wine

I have tried GI and all combinations of relectivity and transparency but just can't get the look right

Does anyone know how to get that perfect glass of wine ? Burgundy, Rose, Beaujolais..not too bothered !!

two work from me with caustics.
caustics depends on glas and contents of the glas.

These al look good especially bobtronics..very rose..however i think there is something missing from the body of the wine, that elusive translucent look with some warm luminosity

Perhaps beter seen in a burgundy, or rioja

I'll take a look at this later on - I love a challenge. Benytones work is nice but he definitely needs to increase the amount of samples. At the moment the caustics look as if they're lights emenating from a silver disco ball.

Maybe you mean the sugar and glycol content of some wines maybe thats whats missing

@ paulselhi: A shadow would add some realism to it, then check the refractive index for glass (somewhere around 1.5) and wine (i am not that much of a wine conaisseur..)

a little bit of translucency could be looking good on the wine.

also try a photostudio lighting to achieve some slick results.

I'll try to have something uploaded when I'm back home.

The Caustics seemed to have limited themselves to the glass only in my attempt
and the wine looks more like cheap sherry than anything else.

I think the color of the wine is too constant, it looks therefore too thick, more like syrup.

For those of you owning translucent-pro: use it !

Have to love the vreel 'transparent' shader which is included in the package.
...still the best approach for color-absorption of liquids, unreached since R8 came out.
Thanks to Arndt :-)

Hereīs the Zip (preset) from my site... god, the years passed by... Nov 2003!

actually, itīs more than old...
wondering why there isnīt still anything similar in R-9.5 or fR-shadertree.
Since years, Arndt shows status-quo with this rarely used (and known) shader.

but... aware of the rendertimes !!!
