Abstract
In movies or games, physically-based simulation has become an indispensable technique to generate realistic animations. In movie productions, the scene is designed beforehand in a storyboard, and while keeping a realistic appearance, there is often a need of non-realistic behavior. During the movie production, the control of the behavior of the objects is slightly possible by adjusting certain parameters of the simulation such as materials. Despite that, setting them to obtain the expected results is a laborious and not a straight-forward process. In this paper, we propose a method for the destruction simulation based on a mass-spring model, where objects are represented as set of elements interconnected by spring, to control the shape of the objects after destruction. We control the shape resulting from destruction by letting the user to specify the hard and the fragile parts of the objects. Based on this information, the toughness of the springs are automatically adjusted. As a result, we can generate realistic destruction animations and at the same time control the shape of the objects after destruction.
