How can one do “realistic looking” glass object in Blender? I mean bottle or drinking glass for example.
Making the material isn’t hard. It’s just the object. Here’s example pics I made in five minutes.
Double-wall glass (bottle): http://kuvax.net/i/?4348pullo_fin.jpg (600 x 600)
One-wall glass (bottle): http://kuvax.net/i/?8785pullo2_fin.jpg (600 x 600)

Glass is thick. That’s a fact. That’s why I tried to simulate thickness at the first place. Thickness consists of the inner and outher surface of the glass. But it also causes double-wall effect (I don’t know what I should call the effect so it’s “double-wall” now). If you look closely the first raytraced bottle you can see both walls. Looks too hollow to me.
I don’t like that. It looks like there’s two very thin glass walls instead of just one thick solid wall.
You might ask why should there be double-wall glass in an emply and “closed” bottle. That’s why I made one-wall glass. It seems bretty OK to me but not too realistic. Besides. It works on this bottle I made, but you just can’t make realistic looking drinking/wine glass with just one wall. If you think I’m wrong, tell me how you’d do it.
