碩士 === 國立交通大學 === 土木工程系所 === 94 === In recent years, 3D computer graphics technology has been developed rapidly. The application of virtual reality (VR） is able to enhance the efficiency of editing complicated information for design such as behavior of structures. The purpose of this thesis is to develop a system for simulating dynamic analysis of structures displayed by VR with the capability of interaction and visualization. Thus, the interactive VR system enables users to design structures with more efficient tool and to simulate the 3D dynamic responses of buildings under earthquakes. This system is designed and developed using the object- oriented and 3D computer graphics techniques in the Microsoft Windows environment, and is implemented using Microsoft Visual Studio .NET 2003. Win32 program design is used to develop the Application Program Interface (API), and it also supports various user-interfaces, such as pull-down menus and pop-up menus to guide the user to run the system easily. DirectX 9.0 is used to develop the API of 3D computer graphics for information visualized, and the dynamic simulation of structures will be displayed smoothly and have more efficiency in interaction. During the process of dynamic simulation, a window is designed to display and compare with different control device, and display the data diagram for the different placement and different kind of the sensor in real time.
