Abstract:  Recently computer graphics has witnessed increasing interests on physics-based sound simulation, an endeavor that exploits physical principles to automatically generate computer animations, audiovisually. In this talk, I will start by briefly showing some of those techniques we developed, and explore what these methods enable us beyond generating virtual effects. In particular, I will present a few recent projects on computational acoustic design—methods that generate desired acoustics by computational design of geometry and material—with the applications on computer animation, personalized 3D printing, HCI, wireless communication, and other engineering fields.

Putting this line of research into a larger picture, I will conclude the talk with quick examples on using computational physics techniques to bring virtual effects to reality, even beyond acoustics.
