Object Modeling and Animation Withparticle -

In this article, we describe a general method for the reconstruction and animation of deformable 3D objects. These objects are initially deened by a closed surface model, which is lled with particles. For this, new particles are progressively generated inside the boundary. When a new particle is introduced, it enters in interaction with all the previously existing particles. It will also collide with the boundary. Then we let the system evolve under the action of physical laws until reaching an equilibrium. With an aim of a medical application, we want to simulate the movement and the deformation of anatomic objects. So we have introduced the necessary tools to take into account the dynamic and deformable behavior of the organs and the surrounding environment.
