Research And Implementing Of X3D-Based Visualized Tool For 3-Dimension Scene

With the combination of Internet and virtual-reality technique,three-dimensional scenic technique has been widely used in many fields,VRML is the most popular data form in describing three-dimensional scenes on Internet. At present,the three-dimensional scenic tools based on VRML are all text-based in China.Users,if they want to employ this tools,need to edit VRML program to develop three-dimensional scenes.Therefore,it is necessary of users to be specialized in VRML mode and master some knowledge such as graphics. So graphics-application lab of Shenyang university of technology,where the author studies,has initially developed graphics-based visualized VRML three-dimensional scenic tools,and users can operate three-dimensional objects to build up three-dimensional scenes by selecting orders in the menu by mouse,without knowing much about VRML mode and granphics.Users can instantly get visual pictures of the three-dimensional scenes,which will be helpful to the quickly development of three-dimensional scenes and application in other non-computer fields.With the development of Internet and extension of VRML appication,the old VRML technique can barely meet the demand of users.Having modified the traditional VRML mode,Web3D Consortium published a new Internet three-dimensional mode in 2001.X3D will take the place of VRML and provide wide scope for the development of Internet three-dimensional graphics.At present there do not exist development tools for visualized three-dimensional scenes based on graphics-driven X3D in China. Therefore,through the research of X3D technique,the article proposes a design and creates visualized tools for a X3D three-dimensional scenes.This article mainly deals with the research on the X3D-based technological creation of the three-dimensional scenes;the aim of developing the tools is to provide users with quick and convenient mode to build non-programming and interactive three-dimentional mode. The scenic-creating process is to choose objects from the objects store and create three-dimensional scenes by building-mode,and then operate the graphics of the objects in the scene.The changes of X3D file caused by the change of three-dimentional scenes are completed by the softwareitself,and hide themselves from users.In the processes of the research and realization of the development tools of the three dimentional tools,quick methods of commanding X3D can be found through DOM technique.Because of the extending ability of X3D,it is difficult for X3D to be formatted. Then the XML Schema technique is proposing a construction mode for the creation of X3D objects.
