Based On Accurate Mechanical Model And The Fdh Tree Collision Detection Algorithm Cloth Simulation Technology,

Cloth simulation is a technology that simulates the falling and damping of clothe by the support of computer,which has a vast prospect in computer graphics.Although spring-mass model is easy to built and efficient in calculation,it is very hard to simulate the physical feature of the cloth.We have to improve this to fit the simulation which needs physical real cloth.In mechanics,we have enough knowledge in analyseing hull structure.So it is very nature to use mechanics to support our cloth simulation.Finite element and volume cloth model is perfect in deducing the forces of the cloth.But this kind of model is too complicated in calculation to fit the real-time simulation.Particle Model with accurate mechanical formulation solves the force in cloth using Finite Element Analysis,which is much precise than mass-spring model and is comparatively efficient in calculation.Cloth are not always alone in the scene in cloth simulation.In the process of the cloth moving in the scene,we must concern the situation of the collision between the cloth and the object. Collision response is always carried out with the help of collision detect which needs to consider the figure of the 3D model and the correlation between the cloth and the model.I use FDH method to detect the collision between the cloth and objects in the scene.When a collision is happening,I use impulse to correct the movement of the cloth.Air-force and friction are also considered in the impulse,which exactly detects and handles the collision between the cloth and the model.The programme is built with Microsoft Visual C++ 6.0 and OpenGL API.The programme simulates the whole process of the interaction between the clothe and the human model.
