Working with Liquids in Glass

[dwr08]

By alll means, please do take Roelands advice; I was not suggesting the opposite.
I was just suggesting an alternate method of doing it that worked perfectly well in Maxwell and Fry, and I guess it's worth trying out in Octane. I'd do so myself now, but I won't be able to give it a go untill the weekend (working 12 hour night shifts currently ).

The fry and maxwell set up don't work in octane.
Can we have some feedback on this or better a working test scene.

What are the fry and maxwell method?

Ok, here's a very quick and sloppy test with the method I mentioned earlier.

Feel free to play with it.

is it physically correct ?

[gordonrobb]

It's modelled the way DWR suggested, but not the way the guy from Otoy recommended. Will test it shortly. Just doing a render.

I've had time to sit down and give this a nice go now. Here are the results:

The glass on the left is modelled following the Maxwell/Fry technique, and the one on the right is modelled having the volumes slightly overlap, as suggested by Roeland.

Here´s the scene (Lightwave) so you can potter around with it:

In the end, it all boils down to a matter of what pleases you most. I personally like the meniscus from the left glass, and the projected caustics from the right one.
