Study On User-oriented Product Virtual Display

With the development and popularization of Internet technology, more and more enterprises set up their own websites, they use the website to promote their own products, collect the personal demand from users, this approach bring a certain extent effectiveness to the enterprises, and also provide greater convenience and to fulfill their own individual needs opportunities to the users. But nowadays, texts, pictures, and flash animation are main ways of products display on the most websites, which are dwelling in only introducing that lacks interaction among men and machines, which is one of factors that retracts products exhibit effect on internet. In order to achieve third dimension environments make looker to be personally on the scene. This subject made a deep research into the User-oriented products virtual display technology.This paper described the products virtual display systems related technologies--Virtual reality technology.On this basis, I have a detailed study of VRML-Virtual Reality Modeling Language. Based on the research on the characteristics of VRML technology, architecture, the model for product and technology in the virtual product model display of the special requirements, this paper proposes the establish the product model by 3D CAD software first, then convert to VRML file formats, against the problems in coordinate system, unit system, we propose our own solutions. In order to make virtual product model in the process of transmission speed can be as small as possible and guarantee the emergence of the distortion products, the paper take research on the VRML file optimization technology.In order to be able to achieve in the virtual world of product model in the process of assembly to comply with the products in the real world in a logical order, this paper studies PROTO-node prototype and product model will be proposed division (with a specific sequence of assembly parts to establish a model of spare parts) and the achievement of the nodes of the group method.As VRML itself in the weakness in HCI, we use Java technology with the combination provided by VRML--JSAI-Java script creation interface and EAI-Expansion of creative ways interface, achieve the virtual scene within the complex animation and virtual settings scenes interaction with the outside world.Finally, above the research results, and combined with JSP, HTML and Web Database technology, proposed the concept based on B/S mode products virtual display system, study implementation of the system software design ideas, principles and methods, structures of the system's overall structure and framework, and give the example of the system's operation.This paper by using VRML constructed the Products Virtual Display System based on the B/S platform, achieve a three-dimensional model of the product enables true dynamic assembly and movement of products covered by simulation, it allows users in the network environment of the performance of the product, understanding of the characteristics of a significant upgrade...
