I will get around to doing much simpler test renders of each of the glasses at some point. Little thumbnails to help people select a glass based on visual appearance rather than on technical data.

I was thinking a sphere, a thin pane, and a semi-complex shape around 5cm in size each would make a reasonably good test scene without sending render times through the roof...

Sound good?

@WytRaven

Sounds good to me. If you need some help to render some scenes, I guess it
would be a good idea to split the work ... so I would offer some CPU time to
speed things up a bit. Maybe some others too ... hehe! ;o))

Ok well I'll put to gether the scene tonite if I have some time and then run a test to find how many samples/pix is needed to give a reasonable result. Then I'll post the scene and we can organise who renders what

Thanks for the offer of help, much appreciated.

suzanne or the teapot? both are nice objects to make test

your tests are very welcome, WytRaven!

The teapot is better than suzanne, but none of them are suited for a glass test, IMO.. You need an object that has a thickness similar to the real glass you want to reproduce, with a single layer (like a window glass)..

couldn't you simply give them thickness? in Blender, there is the function "shrink/fatten", that will make things smaller/bigger on their normals' direction

- that should be possible in *any* app... (... as long as it's not specialized on architectural modelling.... I guess, sketchup doesn't have such a thing? - why should it^^ oh, and topmod *kinda* has it, but not the exact same thing...)

Original post massively updated

quick shortcut back to first post that now contains previews for every glass in the library

Enjoy

Man, that is an incredible thing you've done. You're patience must be almost limitless!

Thank you

Thank you very much, wyt! a very useful work for the community!!

OMG!!
Amazing list!
Do you have an exact time, how long all that together needed?

Yay, now, you can go on rendering your robot elements

Big thanks wytRaven !

Differences are more visible in IoR and diffraction (cauchy), than absorption. Amazing how specular highlights change.

Holy cow! You did it, hehe! Awesome! Thanx a lot for your work mate! ;o))
