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.


P.S. Some of this technique are not Open CL friendly though.



Thanks a bunch for the detailed setup!

Im genuinely curious, where does one start if they want to learn these things?

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.
