Scratch Posted September 3, 2015 Share Posted September 3, 2015 (edited) Hey Folks, I recently heard about Yannik F.'s Q-Solver Plugin for Realflow (275$) which looks really promising for small-scale liquid-simulations (good surface tension, sheeting, etc.) In my opinion even better than some custom fusionCIS stuff). What do you guy's think about it? (There's a lot more RnD stuff on Yannik F's Vimeo-channel) Annother Example: Release-Notes: https://www.youtube.com/watch?v=5Ud8qBa35r8 I'm (still) wondering if something like this is possible in Houdini. I know that Alejandro Echeverry is working on some similar stuff (http://forums.odforce.net/topic/18111-flip-smorganicsheeter-effect/) , but his tool is to my knowledge not yet finished and available for public use. Is there something similar in H? I did some small-scale stuff a few weeks ago, it turned out ok, but the results couldn't get close to the q-solver stuff - even with a surface tension microsolver attatched to my flip-solver. Some the discussion regarding my project and the topic can be found here: http://forums.odforce.net/topic/22272-how-to-emit-additional-small-droplets-from-a-water-drop-crown-splash/. I'm courious what you think! Edited September 3, 2015 by Scratch 1 Quote Link to comment Share on other sites More sharing options...
Farmfield Posted September 3, 2015 Share Posted September 3, 2015 I'm (still) wondering if something like this is possible in Houdini. Dive into a microsolver - or the help for all the gas solvers and such - and I'm pretty sure you can do whatever, it's "just" math, all of it. But Yannik's setups are absolutely awesome, do question about that. Quote Link to comment Share on other sites More sharing options...
Scratch Posted September 3, 2015 Author Share Posted September 3, 2015 (edited) it's "just" math, all of it. Sure, but isn't that something that's needed so often, that there should be some implemented high-level solutions, without the need to dive into vops and microsolvers and a lot of highlevel math? Like a "sheeter microsolver" or a more sophisticated "surface tension microsolver"? My only explaination is that a big flood-wave, a vast ocean or a roaring river (where those effects are less influencial/crucial) is needed more often than a tiny little drop of water, so there might be more (dev-)focus in that direction. But for commercials/advertising, small scale liquid sim is something that is asked for quite often, and there is as far as I know no real (commercial-)solution out there - except from custom built inhouse tools and now maybe the Q-solver plugin that looks very promising regarding sheeting and it's (more realistic) surface tension model.

Diego A Grimaldi Posted September 4, 2015 Share Posted September 4, 2015 Hey Philipp, the guys that made this video are using H for their awesome liquid FX and sadly are using their own custom tools. I don't think they'll share but they got the basic of their tools from Siggraph papers Quote Link to comment Share on other sites More sharing options...

Scratch Posted September 4, 2015 Author Share Posted September 4, 2015 @diego: Inspirational! @marty: Very nice and indeed simple workflow! I'll keep that in mind for my next projects! Thanks alot for sharing your approach! Quote Link to comment Share on other sites More sharing options...
herertik Posted February 3, 2016 Share Posted February 3, 2016 Yes its possible in houdini and like the Farmfield said, its just a math, we did something like this:) But, yes, Q solver is very impressive and inspiriting! Quote Link to comment Share on other sites More sharing options...
