An algorithm is presentedthatenables fast deformation of volumetric objects. Using this algorithm, rigid, defm-rnable,elastic and plastic materialscan be modeled by adjusting deformation limits for individual elements. An interactivesystem thatcombines the deformation algorithm with collision deteetion and an energy minimizing elastic relaxation step is described. Using this system, objects containing up to-125,000 elements have b deformed intem~tivelyon an-SGI Indy.
