A new fluid process hit by Fusion! Air entrainment trails behind projectiles thru a water surface. In this qt showing RealFlow particles, 4 objects are plunged into water at high speed and pull air behind them that forms a pocket in their wake that then collapses into swarms of buoyant bubbles and rises back to the surface. Fusion created this new and challenging effect thru a true team effort over a 1-week schedule to deliver the sim data for a high-speed commercial project. CG artist Luke Olsen came up with the idea for creating a guide geometry for the downward plunge by using an n-cloth sim in maya. Mark Stasiuk begin_of_the_skype_highlighting end_of_the_skype_highlighting created a script that had fluid particles attracted to the cloth geo and filling in space between the fluid particles as the cloth stretched, then releasing at the bottom of the plunge, and disaggregating into buoyant bubbles. Dan Novy worked the sims and meshes to get a nice (if rushed) final look!
