Popular Post 953u6015t Posted September 24, 2017 Popular Post Share Posted September 24, 2017 Few tips and tricks to manipulate gas simulation. 1. Independent resolution grid. E.g. Overriding vel grid size independent to a density grid. 2. Creating additional utilities. E.g. gradient, speed, vorticity and etc which can be used to manipulate forces. 3. Forces via VEX and some example snippets. smokesolver_v1.hipnc P.S. Some of this technique are not Open CL friendly though. 42 33 Quote Link to comment Share on other sites More sharing options...

Im genuinely curious, where does one start if they want to learn these things? 6 3 Quote Link to comment Share on other sites More sharing options...
953u6015t Posted September 26, 2017 Author Share Posted September 26, 2017 (edited) Subjective question, at least this how I started: 1. Shelf tools, learn the basics and concepts. 2. Dive into DOPs OTLs/HDAs and look around to see how they are implemented. My examples are just a product of what those Side Effects guys implemented. 3. Read Houdini's documentation. 4. Be inspired by all the test that posted on Vimeo/YouTube that doesn't look like off the shelf imagery.

Popular Post 953u6015t Posted September 30, 2017 Author Popular Post Share Posted September 30, 2017 Another, focused on instancing smoke objects. Manipulating points with basic instancing attributes, i@cluster, v@scale and f@sourceframe. How to activate smoke object and holding a volume source. This method ideal for triggering independent gas simulation on impact data. Additional examples, e.g. grid clustering method for trail and non-trail which I'm merging from a separate thread. smokesolver_v2.hipnc 31 6 Quote Link to comment Share on other sites More sharing options...

tamagochy Posted October 9, 2017 Share Posted October 9, 2017 It would be grate if you paste explanation in your custom stuff to fast understand what happen there)) But anyway thanks for sharing. 2 Quote Link to comment Share on other sites More sharing options...
953u6015t Posted October 10, 2017 Author Share Posted October 10, 2017 Good point. Something I have to improvise I guess. Initially I wanted to but was lazy, easier to put a setup than writing. I'll consider in future though! Quote Link to comment Share on other sites More sharing options...

Dave Stewart Posted December 21, 2017 Share Posted December 21, 2017 What a goldmine of techniques and ideas, so glad I found this!! Wish I'd known about the independent resolution trick a few weeks ago, that one will really come in handy in the future. Thanks SO MUCH for taking the time to put these together and sharing!! --Dave Quote Link to comment Share on other sites More sharing options...
