Title: From mass-spring system to general hyper-elastic materials -- Towards real-time simulation of deformable objects
Abstract: Traditional FEM based methods are usually considered slow, because simulating those types of FEM materials relies on Newton's method, where even one Newton iteration is too expensive to fit in the limited time budget for real-time applications. Fast methods such as Position Based Dynamics support only a limited selection of materials, and often converge to a different solution compared to the ground truth. From mass-spring system to general hyper-elastic materials, we proposed a series of methods, trying to fill the gap between slow but accurate physics-based animation and fast but ad-hoc real-time simulations. Our final method is typically more than 10 times faster than one iteration of Newton's method without compromising quality. In fact, our result is often more accurate than the result obtained with one iteration of Newton's method.
Bio:  Tiantian Liu is a fourth-year Ph.D. student in the Computer and Information Science Department at University of Pennsylvania. He is currently working with Prof. Ladislav Kavan on physically based simulations, and is also very interested in fast numerical algorithms.  Previously, he obtained his Master's degree in Computer Graphics and Game Technology at University of Pennsylvania, and Bachelor's degree in Computer Science and Technology at Zhejiang University.
