In this neat and pretty little project, Fusion got a chance to take to a new level one of the most iconic of CG fluid simulations: the ice cube + cocktail sim. Co-founder Mark Stasiuk created a classic tutorial on this topic a loooong time ago for RealFlow v3, altho in this case the sim had a lot more to do than just float an ice cube. Here, 4 glasses of Tea's Tea dance happily in time to a catchy tune, moving around on a turntable while spinning and tilting. The ice cubes jumble actively in the tea, the tea sloshes in the glasses.... but never spills out! Of course! To beat physics at it's own game we created a Python-scripted deamon to make a cylindrically-symmetrical force field with highly controllable falloff, allowing the tea to move naturally in the glasses but whenever it tries to spill over the lip, it gets nudged gently back. The resulting sims are rendered in mental ray using the tremendously flexible mia_x_passes shader. Oishii ! (Japanese for delicious!)
Hey, thanks for checking it out. Fusion was responsible for fluid sims for the tea sloshing around in the glasses as well as the models for the ice cubes and glasses. The finished spot turned out great and the catchy song can still be heard in the studio now and then being sung randomly by one of our crew.
