A Survey On Physical Methods For Deformation Modeling

Much effort has been dedicated to achieving realism in the simulation of deformable objects such as cloth hair rubber sea water smoke and human soft tissue in surgical simulation. However the deformable object in these simulations will exhibit physically correct behaviors true to the behavior of real objects when any force is applied to it and sometimes this requires real-time simulation. No matter how complex the geometry is real-time simulation is still required in some applications. Surgery simulation is an example of the need for real-time simulation. This situation has attracted the attention of a wide community of researchers such as computer scientists mechanical engineers biomechanics and computational geometers. This paper presents a review of the existing techniques for modeling deformable objects which have been developed within the last three decades for different computer graphics interactive applications.
