    Abstract: 由於電腦與網際網路的快速發展,使得目前土木工程領域虛擬實境的相關應用更為廣泛。除了將結構設計的結果利用3D虛擬的方式來展示、檢核之外,更導入了互動性的概念,使用者有更好的操作彈性,可借著與虛擬場景作互動性的溝通來取得想要的資訊。
    Because of the fast development of computers and Internet, the applications of
    virtual reality in civil engineering become more extensive at present. Besides the use
    of 3D virtualization to show and examine the results of structural designs, introducing
    the concept of user interaction gives engineers better operational flexibility. We can
    get the information we want by interacting with virtual scenes.
    This thesis utilized several programming languages to cooperate with virtual
    reality to explore the effectiveness of interaction between the user and virtual scene.
    Three systems were implemented to demonstrate and explain the application of the
    technologies. With the design of the interactive procedure, the user can control and
    alter the virtual scenes according to one''s own idea. Interactive communication can be
    achieved by simple mouse dragging and dropping operations in virtual scenes. The
    completed virtual scenes can be stored and browsed again in the future.
    VRML is the virtual reality language used in this research. Combined with other
    programming languages, such as Java, Servlet, Ajax, etc., the interactive features of
    virtual scenes were discussed. In order to develop the interactive 3D reinforcement tie
    modeling system, in which the users can build a new type of tie by assembling basic
    bar components, the existing tie models in the design code were first analyzed and
    generalized to extract the basic bar components. In the interactive 3D building
    modeling system, interactive operation tools written in VRML and Java were used to
    put together non-uniform cross section VRML buildings that represent the main
    building models used in wind-tunnel experiments. The parameter feedback
    mechanism is for retrieving information from a virtual scene that has been changed by
    the user directly in the scene with the interactive features provided. The retrieved
    information reflects the changes and can be fed to other programs for calculation as
    well as generation of new virtual scene.
