This is what a sample site space looks like at a distance. This is the first thing that a visitor to a website would see when they visit the site. Since it's just a framework for the site, the download size of this structural representation is small.

In a directory or on a site, this file would typically be saved as home.wrl. A 3D-only web browser would look for this file the way that 2D web browsers and servers typically look for index.html in a directory or on a site.

Mcubed separates site design from page design from data, and yet all of these can be lumped together if the author desires. Although it horrified old-school SGML hands and created vast angst for site developers when HTML started to be used for serious applications, it was this very lumping together of style and data in the first place that allowed HTML to be adopted so rapidly and so widely. The problem wasn't that HTML allowed this, it's that there was no facility to do it any other way. With VXML, affordances are built in so that it can work just as a 3D stylesheet. Content and design can be separated if the author so desires.

A VXML file format could easily be filtered into a 2D page description language, either print or screen based. The main benefits to the end users of VXML

The nodeUrl field in the VRML or in the XML determines what is loaded when the user navigates (either via a link or via free navigation) into the node's space. What that might look like is described on the next page.
