Abstract
In this talk I will present my research on real-time 3D graphics and virtual characters. In the first part, I will introduce myself and several projects I've been working on. In the second part, I will talk in detail about skinning---a popular method to animate virtual characters in real-time. I will explain how dual quaternions can be used to obtain better quality skinning than the standard technique based on matrices. I will follow with our approach to real-time cloth animation, discussing how to create an upsampling operator that adds fine-scale details to coarse mesh simulations. The main tricks needed to make upsampling work robustly include harmonic regularization (an extension of the classical Tikhonov approach) and our take on "tracking," i.e., constraining fine-scale physics to follow a given coarse-scale animation. Finally, I will conclude with some ideas for future work, for example, how to make digital content creation more intuitive.

Ladislav Kavan is a Research Scientist for Disney Interactive Studios, working with Peter-Pike Sloan. His recent work has focused on combining data-driven techniques with physically-based simulation, subspace methods, and real-time character animation. Ladislav received his M.S. in computer science from Charles University and Ph.D. from Czech Technical University in Prague. Prior to joining Disney, he was a Post-doctoral fellow at Trinity College Dublin, working on character animation and crowd simulation projects.
