Description:
There are few who seem to follow the laws of physics these days, so here's an accurate representation of fluid in a glass (which is not quite as simple or obvious as you might think)
See this post on my blog for why you've been doing it wrong all these years: http://adaptivesamples.com/2013/10/19/fluid-in-a-glass/

Written October 20, 2013It is good to know that, mainly when a glass of liquid is in the foreground or is the main object of interest. Thanks very much.

Written October 20, 2013I have used another approach, I don't know if it is better or worst: using the wrong mesh, if you make the internal glass faces which is touching the water transparent the result is very similar. You can improve it making the top of the liquid concave, as you said in your blog.

Written October 22, 2013I suppose that works, but rendering lots of transparency in Cycles is very slow when it adds up. Might not make too much difference here, but when there's a few glasses next to each other it'll bog it down.

Written October 21, 2013Hi Greg, I tried to visit your link and my anti-malware software said I couldn't go to your site.

Written October 22, 2013Sorry, use a different malware program ;) or there's probably a whitelist of sorts for you to specify places you trust.

Written November 11, 2013Yeah, I don't know why it was ornery that day, but it seems to work fine now with no complaints!

Written November 28, 2013Doing a render right now for a few of my homebrew bottles+labels this has helped me a lot to do it right!
Thank you Greg! :D

Written January 14, 2020I never knew I was supposed to do all that I just made a glass then extruded the inside as the liquid. https://www.deviantart.com/ztip5/art/Wine-Glass-Red-825785079 I thought it was fairly good for my first blend and no instructions.
Greg, I've followed your work for a couple of years now. Thanks for the tutorials you used to do and I see that you are in more formal productions these days. Best of luck in your future endeavors.
Thanks for the physics lesson. We should all strive for realism when the model/scene requires it.
And a special thanks for your generosity for taking the time on occasion to mentor those of us who are trying to improve with each new model and scene.
