    Abstract: 3D視覺化技術比2D的展示方式更能提供使用者更逼真的視覺認知感受;此外使用者可以自由的在3D環境中操控視點及視線方向來得到更多的資訊。要建立一個3D的虛擬環境需要許多的模型及資料;例如,地形、建築物、車輛、及植物等,甚至於一些大氣壓力、氣溫、速度、溼度、及磁場等環境資料。當虛擬環境中的模型數量太多或環境資料太複雜時,管理模型及資料就變得非常困難。因此需要一個完整統一的規範來描述所有的虛擬環境模型及資料。 在本論文中,我們提出了一個以SEDRIS為基礎的虛擬環境編輯及瀏覽系統。SEDRIS是一個可以完整描述環境資料的軟體工程技術。我們所提出的系統包含編輯器、瀏覽器、容易操作的使用者介面來操控模型,及兩種不同的瀏覽模式來瀏覽虛擬環境。此外我們還提供飛行路徑編輯器,方便飛行模擬應用的演練及重現。 3D visualization technology offers more realistic presentation than 2D visualization technology offers; moreover, user can choose arbitrary views to visualize more information in a 3D environment. Constructing a 3D virtual environment needs many models such as, terrain, buildings, vehicles, vegetation, etc. and fluid data such as, atmospheric pressure, temperature, speed, humidity, magnetic field, etc. If huge amount of models and complex data are included in a virtual environment, the management of the environmental models and data will be very difficult. Thus we need a complicated representation and specification to describe the whole virtual environment. In this study, we purpose a virtual environment system based on the synthetic environment data representation and interchange specification (SEDRIS). SEDRIS is a software engineering technique for describing complicated virtual environments. We utilize the technique to unambiguously represent 3D objects and their attributes to build a virtual environment. The proposed system includes an environment editor, a browser, a user friendly interface, a facile model manipulation, and two kinds of views in the virtual environment. Moreover, we provide a flying path editor for the virtual environment system such that we can demonstrate or rehearse a fly through simulation.
