Use PHP to dynamically generate a virtual reality web page

I have been engaged in 3D animation many years ago. After learning PHP, I found that I can use PHP to dynamically generate the OpenGL document, which is a bit similar to the Generator to dynamically generate Flash.
Due to the wide and profound knowledge of VRML, here is only a simple example. You can also store various types of VRML nodes into the database. Such a web page of virtual reality will ......, Great!
The following is the source program. Note: on the server, PHP is required to process wrl-Format documents. Otherwise, there will be no virtual reality. Source program directly saved into wrl files, in the browser to install plug-ins, you can go to my another home page download: http://go.163.com /~ Sjtucaocao/
