The 3D dynamic simulation is rendering by the time series information of Geographic Information System and the dynamic features of X3D. The developed 3D simulation model is embedded into the software environment of Geographic Information System ArcView. The user could use the interface of Geographic Information Systems to do the X3D simulation. The simulations of the effect of wave, current on the coastal evolution were done by the developed X3D GIS model respectively. And the combined simulation of the effect wave, current on the coastal evolution was also demonstrated in this research. The model of combining Geographic Information System, numerical computation and X3D simulation is developed to provide dynamic 3D simulation of the coastal evolution is this research.中文摘要...................................I Abstract...................................II 目錄.......................................III 圖目錄.....................................V 第一章 緒論................................1 1.1 研究動機...............................1 1.2 研究目的...............................2 1.3 論文結構...............................3 第二章 地理資訊系統介紹....................4 2.1 地理資訊系統...........................4 2.1.1 地理資訊系統定義.....................4 2.1.2 地理資訊系統的資料格式...............6 2.2 ESRI ArcGIS............................7 2.3 地理資訊系統發展近況...................12 第三章 X3D虛擬實境.........................19 3.1 什麼是X3D..............................19 3.2 X3D的場景圖概念........................21 3.3 X3D的事件傳遞概念......................23 3.4 X3D的優點..............................24 第四章 系統架構............................27 4.1 系統概念與流程.........................27 4.2 地理資訊系統的地理資料擷取與轉換.......28 4.3 物理現象的模擬與建立X3D資料............30 4.4 輸出結果瀏覽...........................33 第五章 應用案例實作........................35 5.1 前處理作業.............................35 5.2 建立X3D資料............................39 5.2.1 地形變化.............................39 5.2.2 波浪.................................42 5.2.3 潮汐.................................43 5.3 結果整合...............................44 第六章 結論與建議..........................46 6.1 結論...................................46 6.2 建議...................................47 參考文獻...................................49 附錄1......................................51 附錄2......................................54 附錄3......................................585152450 bytesapplication/pdfen-USGISX3DXMLVirtual Reality3D GISthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/51033/1/ntu-96-R94525026-1.pdf
