The Research And Design Of The Management System Of The Online Virtual Stores

Virtual display has been widely used as an important complementary of physical display in developed countrieso We are backward in this field, there is no theory and methods in development technology of virtual display system, particularly lack of an effective development platform to design and produce a hall. Virtual network technology opens up a new way for company and customer to exchange information. The development of virtual reality technology makes the ultimate realization of the "real" online virtual display come to true. Therefore, this paper' s research has broad application prospects.This paper presents a interactive virtual stores management system based on VRML/X3D. Papers introduce the virtual reality technology and research in e-commerce applications. VRML/X3D studies use virtual reality technology with the current online shopping technology platform, introduce design of the system structure in detail. This paper introduces the critical technologies of construction of the 3-D virtual dimensions. The detailed content and the programs are as follows:1,The structure and pattern for researching of 3D virtual stores.In order to improve the safety and performance of the system, and be easy to improve and upgrade the system in the future, we adopted MVC structure. Packaged the key information and most logic processing are concentrated on the server to improve system security and performance.2,The study and implementation of collision detection in virtual store.The collision detection of 3D scenes plays an important role in improving the authenticity and enhances the immersion. Considering the characteristics of virtual system and the requirements of interaction, the system adopts a method based on the region-ray for collision detection to obtain a relatively good balance between speed and performance.3,The study and implementation of real-time interaction in 3D virtual store.(1) Research and implementation in real-time objects addition in 3D virtual scenes, we can dynamic add objects to virtual store in the web by the means of JavaScript through EAI.(2) Research and implementation of location of the objects in the 3D scenes.We can obtain information of the objects in 3D scenes which was saved to the database by the means of JavaScript and JSP.(3) Research and implementation of update material of the objects in 3D scenes. We can update material of the objects through dialog which was made by JavaScript.The creative of the work is list:1,Propose a collision detection method for 3D virtual stores.2,Propose and achieve a virtual scene associated with the database.3,Research and implementation of location of the objects in the 3D scenes.Papers analysis and descript the system' s operation, finally, Summed up the online virtual store system development study, and point out the future research direction.
