UCLA Math Behind Disney's Latest Animation Film

The Math of Making Snow

UCLA alumnus Alexey Stomakhin (from the left) and UCLA mathematician Joseph Teran attended the wrap party for the movie, along with two UCLA math students.

Thanks to the latest material point method (MPM) technology created by UCLA Animators, Alexey Stomakhin, Craig Schroeder, Lawrence Chai, Joseph Teran and Andrew Sell, Disney has been able to simulate an incredible realistic snowy environment in its latest animation comedy, FrozenThe following video was presented at the computer graphics conference Siggpath and explains the mathematics (utilizing a user controllable elasto-plastic constitutive model integrated with a hybrid Eulerian/Lagrangian Material Point Method) involved behind the snow simulation and dynamics used in the film. Watch the below video for various realistic simulations of the "snow" in action.
