Recent decades have seen the dramatic rise of computer graphics and physics-based animation---from early algorithms to sophisticated software systems and parallel architectures. Unfortunately, as we race toward highly interactive and realistic visual experiences, it is becoming obvious that something is still lacking: realistic sound. For starters, most current physics simulators are inherently silent, so sounds are added as afterthoughts often having little to do with the animated geometry or physics. Compared to computer graphics, algorithms for rendering realistic and synchronized sounds for virtual objects are still in their infancy. My talk will cover the challenges of physics-based sound rendering, and discuss recent progress on sound models for contacting rigid bodies, the noisy nonlinear vibrations of thin shells, familiar splashing and gurgling sounds of water, and a few brittle objects smashed along the way.
