This overview provides a brief high-level summary of the Moving Worlds proposal for the VRML 2.0 specification. (The full proposed spec is available at http://webspace.sgi.com/moving-worlds/spec/spec.main.html.) The purposes of the overview are:

• to give you the general idea of the major features of the proposal, and
• to provide a summary of the differences between VRML 1.0 and Moving Worlds.

The overview consists of two subpages:

• Summary of Moving Worlds
• Node Changes since VRML 1.0

Even if you've read an earlier version of the Moving Worlds proposal you should still look over the latest version; some far-reaching changes have been made since the first public version, and many pieces have been clarified or developed in more detail.

This overview assumes that readers are at least vaguely familiar with VRML 1.0. If you're not, read the introduction to the official VRML 1.0 spec. Note that Moving Worlds includes some changes to VRML 1.0 concepts and names, so although you should understand the basic idea of what VRML is about, you shouldn't hold on too strongly to details and definitions from 1.0 as you read the Moving Worlds proposal.
