Study And Implementation Of Modeling Flexible Objects Based On The Hybrid Method

With the slather application of flexible object, and the prosperous development of technique of virtual reality, it is important to modeling for the flexible object on the computers, especially the cloth that has close relation with people. It would have great effect for the clothing field if we know the appearance before the cloth was made. So, it has profound and lasting meaning for flexible and clothing industry to molding the cloth putted on the people or on the desk by computers. This paper makes great contribution to the further research of flexible objects through modeling the flexible material.The model of simulating cloth usually has three kinds. (1) Geometric model (2) Physical model (3)Hybrid model. The geometric has the advantage of faster modeling, but it hard to attain the precision pattern which in order to add dynamic effect. The physical model can get dynamic effect, but it would consume great time. The present hybrid model could attain the dynamic effect in shorter time, but it does not consider the series of different motive states. To solve the above problems, this paper stated from the composites, fabric. It considers the properties such as geometric, physical and energy of the cloth, sufficiently. On this basis, it analysis, and model the cloth on a desk. Through this work, the problem of real time is mainly solved in computer. A new algorithm for the adaptive triangulation of Curved Surface and A new algorithm for the collision detecting and dealing with are putted forward. These algorithms decrease the consumed time in triangulation- curved surface. Advance union of precision and real time.
