Abstract
A method is provided whereby the user can view and interact with live, realtime 3D content using just a web browser, requiring no extra downloads or third party 3D plugins. The invention uses W3C standard bitmap formats, typically JPEG or PNG, as the delivery vehicle for server side rendered 3D content. The invention provides a 3D rendering application that runs on a web server and responds to commands from the user's web browser to manipulate, re-render and deliver new 3D rendered scenes back to the users' browser. The invention preferably uses Ajax - Asynchronous Javascript and XML to create the client side Web 3D scene manipulation tool set.
