The contents of media going into diversification, it comes to fail to present all these in the traditional 2D information. As the result, the form of 3D information is getting more popular, especially through the World Wide Web, like the on-line games, e-commerce, virtual agent. With the related 3D technologies, we can see the various logics of 3D information structure on the net, for example, VRML, Flash, QuickTime VR, and many other rendering engines. However, although we are accustomed to a real 3D environment, 3D information on the monitor is kind of unfamiliarity, and not only a user, but designer is in confusion at these new media and numberous methods. The traditional image-based information has a linear structure, so it is incongruent for the web, which needs a frequent update and expansion of the information. To work with this new media environment, it is necessary to establish a proper design process and a guideline for designers.
This thesis purports to propose a new logic of information structure, based on the analysis of the features of the existing 3D information structures on the web, and to prove the usefulness of the proposed logic by the application for the customized eCommerce. The practical development of program was followed by the evaluation of presence, to find the factors related with end-users. At first, this thesis introduces the basic concept and major features of 3D information transmission by reviewing and categorizing the various types of 3D information. Then, based on the research on the related Web 3D technology, the classification of 3D information by the logic of information construction is proposed. Next, the problems in each logic of information construction are examined, followed by the propose of the new logic of 3D information structure, which is grounded on the analysis of those issues. Then the new logic is applied to the customized eCommerce, developing the ordering program for a client system. This program is evaluated from the point of developers and end-user, to verificate the usefulness of the applied logic. Finally, findings of this study are summarized and further study are proposed, presenting kind of possibility in applying a new logic in developing an effective 3D information structure.
