Title: "Generating Synthetic Motion Using Physically Based Simulation"
Realistic synthetic motion is required in applications ranging from commercial entertainment to surgical training. However, generating realistic motion for complex objects is a difficult task because of the large amount of data that must be specified and because humans are very good at detecting unnatural or implausible motions. I have explored one possible solution to this problem: using physically based methods to automatically generate motion for animated objects through the numerical simulation of their physical counterparts. In particular, I have developed a series of techniques for modeling the behavior of passive systems such as water, cloth, and breaking objects, as well as techniques for coupling multiple, heterogeneous systems together. In this talk, I will emphasize recent research on modeling fracture propagation in a dynamically restructured finite element mesh in order to animate objects that can crack or tear. Because my goal is realistic motion, I will also discuss evaluation techniques such as user testing and side by side comparison with high-speed video footage.
