In Dreamworks Animation’s Megamind, the production faced a challenge in creating a shot where the top of a skyscraper is torn off and hurled down a city street, destroying portions of the city and creating a massive dust cloud. Development for this shot inspired a new fluid simulation framework with significant improvements in four areas: speed, visual quality, setup flexibility and artistic control. In this talk we describe the simulation algorithm and the framework that allowed it to be used in our effects pipeline.
