    Abstract: 3D視覺化技術提供使用者更逼真的視覺認知與感受;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。如果我們希望建立出非常逼真的虛擬環境,我們所建立的虛擬環境系統必定包含許多資訊與各種屬性。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。合成環境資料表示與交換規格(Synthetic Environment Data Representation and Interchange Specification, SEDRIS) 就是一個可以完整描述虛擬環境資料的標準規範。 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。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。此外我們還提供屬性編輯器,方便使用者編輯環境中的屬性。 3D visualization technology provides more realistic presentation than 2D visualization technology offers. We can choose arbitrary location and direction of cameras to visualize the 3D virtual 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. When a lot of models and complex data are included in a virtual environment, the management of the environmental models and data will be very difficult and very important, so we need a complicated representation and specification to describe the virtual environment. In this study, we provide a synthetic environment system (SEsystem) which is based on the synthetic environment data representation and interchange specification (SEDRIS). The SEDRIS is a software engineering technique for describing a lot of models and complicated data in virtual environments. We use the technique to clearly represent 3D models and their properties to build a virtual environment. We emphasize the structure of property in SEDRIS; we describe methods to set properties into models, and offer an importer for file transformation between SEDRIS and the other file formats.
