this is an Excellent article, the way its set out with the vids and pics. very technical but not rambley. I learnt alot out of it.
Bob would have been proud
Congratulations Lukas:) Amazing piece of 3D parametric shader:) thank You for sharing Your knowledge:)
Entagma is back with another great Houdini guide. This time, Moritz Schwind shows how you can generate Rayleigh-Taylor instability inside the tool. The artist presented a pretty simple setup that will let you get some amazing fluid swirls with cool details.
This was one of the questions we received while on season break: How would we go about creating a Rayleigh Taylor instability. After quickly brushing up on our fluid dynamics knowledge and conducting quite a funny real-world experiment (“Let’s see if this really works!”), which involved microwaving dye, we came up with a pretty simple setup that nevertheless generates quite amazing detail in the fluid swirls that are so typical of the phenomenon called Rayleigh Taylor instability.
The team recommends watching a couple of videos below for more details on the instability:
