Abstract
Realistic motions of articulated bodies are usually generated by using physically-based animation methods such as constrained dynamics. However, these methods involve heavy computations and complicated numerical methods. We present an alternative way of solving constraints of articulated bodies. Our objective is not physically correct motions but visually plausible animation. In our method, each object of the constrained body is first moved according to their physical parameters and external forces, without considering any constraints. Then the objects are translated and rotated to satisfy the given constraints. Instead of strict simulation of physical laws, we suggest procedural formulations for solving constraints. This formulation has the power of generating visually plausible motions as presented in our example animation sequences. Since our method is free from complex numerical methods, it is fast enough to be used in real-time applications such as virtual reality, computer games and real-time simulations. Numerical stability is another merit of our method. This procedural approach can be an alternative to strict physically-based animation methods.
