In this paper we describe a system to generate in an interactive way and thinking in multimedia applications, realistic simulation of a 3D deformable object’s. The physically elastic deformation techniques are actually an important and challenging feature in applications where three-dimensional object interaction and behaviour is considered or explored. Also, in multimedia environments we need a rapid computation of deformations with a good visual realism. In this paper we present a prototype of a system for the animation and simulation of elastic objects in an interactive system and under real-time conditions. The approach makes use of the finite elements method (F.E.M) and Elasticity Theory. Using picking node selection the user can interactively apply forces to objects causing their deformation. The deformations computed with our approach have a physical interpretation based on the mathematical model defined. In particular we extend our original system to non-homogeneous regions. This property is very important to able simulations with material that have deferents density functions. Finally, a set of results are presented which demonstrate this capability. All programs are written in C++ using POO, VRML and Open Invertor tools.
