Dynamic Cloth Animation in Virtual Environments

Dynamic cloth animation is an important problem in virtual reality, in which the reality and real-time effect becomes the main problem to resolve. To achieve the reality of animation, two aspects of research have been done. The mass-spring model is one of the main adopted models, but it has the "super elastic" effect. In this paper, compared to the previous method of deal with this problem, a feasible method is proposed. Besides, how to design wind is also a key problem, in this paper, a function and an algorithm for wind is also proposed. To achieve the real-time effect, the idea of bounding boxes hierarchy is applied in collision detection and self-collision detection. For collision detection, the authors describes a detailed algorithm; for self-collision, art algorithm is described that convert collision detection to self-collision detection. The simulation is executed with an average PC, and a live real-time result is achieved
