Using PHP to dynamically generate virtual reality VRML Web page

Years ago I began to engage in three-dimensional animation learning, after learning PHP, found that can be dynamically generated through PHP VRML document, a bit similar to the generator dynamic generation of flash mode.
Because of the profound VRML, here only a simple example, can also be a variety of VRML node into the database, such a virtual reality page will ..., cool!
The following is the source program. Note: On the server, you will have PHP process documents in WRL format, otherwise the consequences will be no virtual reality. Source program directly into the WRL file, in the browser to install Plug-ins, you can go to my other homepage to download: http://go.163.com/~sjtucaocao/
