Yancy Lindquist is head of Head of Fx, Dreamworks Animation has been posting a few tutorials showing how to do some really cool things within Side FX Houdini. The most recent, is a look at using Houdini to create a liquid Flip simulation as if it were in zero-G.
Yancy shows how to create the liquid flip simulation that ultimately is based on limiting the behaviors of the liquids. Loosely basing the tutorial on some theories of forces governing matter, developed in the 17th century theoretical physics world.
One substance in the Flip simulation will try to attract and stick to itself, while the other will be drawn to cover the first substance in the simulation. The final result offers a really nice zero gravity effect over the particles in the flip simulation.
