Research On Collaborative Design Framework Of 3D Based On The B/S Mode

With the continual development of the Internet technology and computer technology, design activity is moving towards international development increasingly. Since a company's partners and even its departments are often design the same product at different area, this makes it difficult for designers to share information each other. The 3D model is the most important media for communication between the designers, so 3D model of web-based collaborative design (NCD) develops rapidly and is gradually applied to the area of product design. The application of this mode can improve the duality of products, shorten design periods and reduce design cost to make the products better meet increasingly complex demand of the market.This thesis explores the technology about collaborative design of the B/S-based structure. First, we introduce the sense of collaborative design, current research status of domestic and overseas, and the warranty of the selection of this theme. And then we research the technology of software realization. Above all, on the basis of the research I present the basic system structure of collaborative design system based on the B/S (Brower/Server) structure.The main research contents are briefly summarized as followed:1) The architecture and the requirements of functions of network-based collaborative design system are researched and introduced. Then a prototype of remote collaborative design system of B/S-based structure is raised.2) The technologies of Java Applet and Java 3D are researched. Then on this base the realizing methods of using software which is about the display andoperation of the 3D model in client under the web environment are raised.3 ) Data communication on network is researched. The method about the data communication with socket and TCP/IP protocol is proposed. Reliability and real time of the transmitting messages is ensured.4) The technology of XML is researched. Then using XML presents the information in the process of collaborative design and encapsulates the messages in process of communication.5 ) Other crucial technologies about the network-based collaborative design system are researched. Then the applications of above technologies in the system architecture of this thesis are expounded.
