| Now with the electronic games, virtual reality, CAD development, the quality of computer simulation is required more and more high. But in real life not only rigid objects, but also have flexible object. As a result of the rigid body simulation after long time development, related technology has been relatively mature. So the flexible object simulation research more and more important, and flexible object simulation research has become a hot research topic in computer graphics.Generally there are three kinds of methods in the process of simulation of flexible object: They are geometric model, physical model and hybrid model respectively. Physical model not only can simulate the change of the flexible object shape, but also in-depth analysis of internal force of flexible object, let the simulation more real, which is based on physical model simulation has become the focus of researchers.In this paper, it uses the physical model that based on the method of simulation of the deformation of soft objects for research.This paper first introduces the flexible object simulation research status quo and existing problems. The second chapter compares the common flexible object modeling method, and decided to use the mass-spring model in this paper. The third chapter deeply studies the flexible object modeling method, and using the mass-spring model to model, and use integral method to solve the model. In chapter four, a study on the collision detection and collision response in the process of simulation, Collision detection prediction including time and distance prediction method. In chapter five, first introduced the relevant knowledge of OpenGL, use mass-spring model to modeling the drape of fabric, then Implementation of flexible object simulation based on OpenGL.The last work in this paper is to summarize the experimental results, and Plan for the future research. |
