中文摘要：

对虚拟现实建模语言VRML可视化编辑器进行了研究，设计并实现了VRML可视化编辑器Visual VRMLEditor。构造了一个节点树视图，描述VRML文件的内部数据结构；构造了一个三维场景视图，显示了VRML文件所描述的三维场景；构造了一个路由视图，将路由这种无形的机制进行可视化编辑。实现了将节点树视图和三维场景视图结合起来，方便用户操作。此外，将路由这种无形的信息可视化，使用户能够进行可视化编辑路由，不用记住繁琐的VRML语法规则，提高了编辑VRML文件的效率。

英文摘要：

A research on visual VRML editors, which is designed and implemented. It constructs a node-tree-view to describe the inner data structure of VRML files and a 3D-scene-view to show the 3D-view which is described by the VRML files. It constructs a route-view too, making intangible mechanisms visual. This editor can bold the node-tree-view and the 3D-scene-view, which is convenient for users to operate. Moreover, this editor can make invisible information like routes visual and make users edit routes visually, without memorizing the fussy VRML grammar rules, which increases the efficiency of editing VRML files.
