Study Of The Theory Of Three-dimensional Fitting

Virtual Reality is the new practical technology that concerns with many subjects. It is extensively applied in the fields such as business, education, entertainment and military affairs. The fast development of Virtual Reality technology makes it become more popular and widely used on the internet.Nowadays, the trade of clothes on internet is limited because the virtual mall can only show some picture of clothes to customers. It is far away from the conception of "Virtual", and the client would rather go to a real shop to buy the clothes because they can try clothes on. This article realized a clothing system on client side, independent of the speed of server or network, and it is especially suitable for e-commerce.First paper realizes a browser that carries out the personalization of customers' body more easily than VRML. At clients end paper corrects a standard model with body data that a customer offers and gets a body model of that customer. Paper builds rigid models for nori- rigid garments and puts forward a new model matching algorithm, using 3D model and garments characteristic data to make the model try a garment on. At clients side, the trying-on system needs customer offer 3 feature data. Then the system can get a composed model of garment that customer selects and the costumer's personalized body model, to let customer appreciate.To realize the dynamic performance of customer model wearing clothes, it is necessary to study the dynamics model of garments. Paper considers garment is formed by some pieces of cloth, then the research of the dynamics model of cloth is the basis of the dynamicsmodel of garment. Paper have put forward a practical method for dynamical cloth model, then realize a imitating system using this model.
