隨著電腦科技的發展，電腦視覺化的技術日益進步，將3D技術應用在網路上的需求也逐漸提高。本研究將以網際網路虛擬實境技術Extensible 3D (X3D)來實做系統。透過X3D與JAVA程式語言結合，建構出一套具有人機互動效益的3D場景編輯工具。此系統讓使用者可以直接在3D場景中取得物件屬性並且編輯它，因此可以建立出一個更簡單更好用的3D場景編輯環境。

The evolution of the computer technology and the rapid development of the visualization technology are increasing the demand of using the 3D technology on the network. In this study, we employ a network-based virtual reality technology called Extensible 3D (X3D) to implement the system. We construct a 3D scene authoring tool with the capability of human-interaction by the combination of X3D and JAVA programming language. In the system, the user can get attributes of objects and modify them in the 3D scene directly. For this reason can establish the 3D scene authoring environment that is simpler and easier to use.
