"Physically-Based Simulation for Robotics and Animation"
Abstract: Modeling motion is central to all computational disciplines that deal with representations of dynamical systems in the physical or virtual world. Some applications include interaction with virtual environment, human modeling and simulation, design and assembly of electronic appliances and mechanical systems, surgical training, manipulation of nano-structures, physics engines for computer games, special effects and feature animation. There exist numerous motion synthesis approaches: geometric-based techniques (such as key-framing), data-driven methods (such as motion capture), physically-based simulation (derived from law of physics), behavior and high-level cognitive modeling. Each of these techniques has its strength and limitations; the choice of techniques largely depends on applications.
In this talk, we will focus on some of our ongoing efforts on physically-based modeling for realistic, predictive simulation of physical phenomena. Specifically we will introduce novel algorithms on continuous collision detection for articulated bodies and deformable models, adaptive forward dynamics for animated characters and autonomous agents, and constraint-based planning for serpentine robots and flexible objects. We will also demonstrate the results on some interactive applications, including real-time mobile interaction with VR training systems and catheterization procedure for liver chemoembolization.
