Developing Of An Interactive Community Of Online Product Display System

With the development of information techniques, there are more and more ways from which people can get information. Mean while, as development of network, customer consuming patterns are subject to gradual change. Network promoting became a main sales mode of advertisement. Computer VR display systems get more acceptance from the market. This thesis brought out an Interaction Community of Online Product Display System(COPD System).It provides communication between users, online exhibiting of produces and online trading. This system emphasizes graphic effect and running efficiency. This thesis discussion from original engineer, Concept designing, market analyzing and availability analyzing are presented to develop the system. Two techniques are used to optimize the graphic effect of this system, which are 2D skeletons and Z axis space. The running efficiency is dramatically raised by using image compressing and dynamic loading techniques.The development of this system includes community module and display module. They are developing independence. Development of display module needn't network. It can develop offline. It can show the production in 3D view. There are better presentation and more humane way to interact with one of its characteristics. For community part, the network is very important. It is characterized by real-time network. Need to consider multiple users log on to the same system when the whole system operation efficiency and image quality. The main focus of this paper in a virtual interactive community section, which main contents include:(1) Graphic technique and optimizing: In graphic expressing, the system uses a 2D skeleton technology and Z-axis space to strengthen the system screen. As the details of the screen are more frequent when the image is updated and changes, the system significantly decreased operating efficiency, optimization of the screen is inevitable, because the system uses a depth of three-dimensional image, so the optimization part of the image optimization using the LOD Technology, that is, the details of scenes and characters based on the distance from the screen, the details of the optimization. In addition, the character animation using flash CS4 the newer 2D skeletal system, making the community the role of the system's performance in the action even more nimble and lively, like traditional animation as no longer to adjust as each body part, so That is also part of the character animation system, improved work efficiency and shorten the production cycle produced the entire system.(2) Data loading technology: the development of the biggest problems and difficulties encountered mainly in improving the speed of the whole system and how to better present the picture out of the system under study because this is a procedure for the browser to play online. The program itself contains only a simple interface information, almost all of the data stored in the corresponding directory server, and create a simple database. To avoid the system is slow to load and users wait too long, so we developed in the development of the corresponding data in the loading mechanism, making the system significantly reduced loading time.(3) Development and system expansion editor: usually a large graphical application can be used in logic programming languages to form, while the interactive system, similar to the game community as a large map of the scene in the graphic elements of data structures is difficult to process applications to control the overall feel. To address these issues specifically developed to facilitate the map editor graphic arts staff to the way the graphic elements assembled into a large map, this production methods similar to the game engine development even after the completion of the entire system is still able to continue to expand, Create a new community map without having to use the program for help.(4) Database and network communication technology: a database designed and implemented large user information data will be maintained on the server side, using third parties such as ASP or PHP scripts to support the user's browser communication between remote server and other users, how Tens of thousands of Internet users the server will be linked in real time, and flash and PHP Taiwan before and after implementation of the interface is one of the key research in this thesis.
