Art of Destruction (or Art of Blowing Crap Up)
Destruction pipelines today are key aspects of any major visual effects pipeline. Many current pipelines are based on Rigid Body Simulations (RBS) or otherwise referred to as Rigid Body Dynamics (RBD), but a new solution – Finite Element Analysis (FEA) – is beginning to emerge. In this ‘Art Of’ article, we talk to some of the major visual effects studios – ILM, Imageworks, MPC, Double Negative and Framestore – about how they approach their destruction toolsets. In VFX and CGI, RBS is most often relevant to the subdivision of objects due to collision or destruction, but unlike particles, which move only in three space and can be defined by a vector, rigid bodies occupy space and have geometrical properties, such as a center of mass, moments of inertia, and most importantly they can have six degrees of freedom (translation in all three axes plus rotation in three directions).
Brief Bio Fedkiw received his Ph.D. in Mathematics from UCLA in 1996 and did postdoctoral studies both at UCLA in Mathematics and at Caltech in Aeronautics before joining the Stanford Computer Science Department. He was awarded an Academy Award from The Academy of Motion Picture Arts and Sciences, the National Academy of Science Award for Initiatives in Research, a Packard Foundation Fellowship, a Presidential Early Career Award for Scientists and Engineers (PECASE), a Sloan Research Fellowship, the ACM Siggraph Significant New Researcher Award, an Office of Naval Research Young Investigator Program Award (ONR YIP), the Okawa Foundation Research Grant, the Robert Bosch Faculty Scholarship, the Robert N. Noyce Family Faculty Scholarship, two distinguished teaching awards, etc. Currently he is on the editorial board of the Journal of Computational Physics, Journal of Scientific Computing, and he participates in the reviewing process of a number of journals and funding agencies.
