VRML Visual Design And Implementation Of Integrated Editing Environment

Virtual Reality Modeling Language (VRML) is a file format for describing interactive 3D objects and worlds. In order to construct dynamic and various virtual scenes and not to face with lots of codes and complex syntax, VRML programmers urgently need a WYSIWYG developing environment.We design and implement the visualized VRML Editor with IVF(Interactive Visual Framework) and Scene Graph/Viewer architecture of Template Graphics Software, Inc. We create a Tree View to describe the scene graph and it' s hiberarchy, and implement all the nodes defined in VRML97. We make a ROUTE View to implement the Event Routing Mechanism inorder to Edit ROUTE comment. We still construct a 3D Scene Graph View todisplay and handle with the 3D Scenes described by VRML files.One innovation is to display and edit VRML scene graph by "node ?field-fieldValue " tree diagram. The other is to present the visualization for ROUTE comment. Thus, we succeed in combination with visualized editing for static scenes and ROUTE comment.
