Deformable object : surface deformation game engine

Abstract

Physically realistic modeling and manipulation of deformable model is essential to computer graphics, games and virtual reality applications. In addition, simulation of deformable model is an interesting topic and difficult to implement because of the demanding of high interactivity and accuracy. In computer games domain, the process of object deformation must be fast enough to provide useful feedback to animator. On the other hand, the researches on deformable model are ranged from geometric methods to physically based methods. Thus, a great deal of works has been done and a large variety of techniques have been proposed since pioneered work by Terzoupolos in 1987. Currently, the main issue in deformable model development is to model the surface deformation in real-time environment. This research will develop a surface deformation modeling technique arising from interpenetration of rigid body and deformable body. To create the deformed surface in realtime environment, a multi-resolution approach and unequal shearing parameter will be used to calculate the surface deformation. From previous deformation actions, it simulates the behavior of the object materials that show the elastic and inelastic reactions. The importance of surface deformation modeling is to emphasize dynamic interactions of computer generated animation such as collision of object or a bouncing ball.
