This video demonstrated our technique forapproximating the sounds that are generated by the motions of solid objects.  As the motions of the objects are computed, theirsurfaces are analyzed to determine how the motion will induce acoustic pressure waves in the surrounding medium. Our technique computes the propagation of those wavesto the listener and then uses the resultsto generate sounds corresponding to the behavior of the simulated objects. Furtherdetails are provided in our paper in the SIGGRAPH 2001 proceedings.
