Technologies behind AJAX3D

AJAX3D is based on the integration of two programming models:

• the W3C Document Object Model (DOM), a model for programs interacting with a Web document
  • In particular: XMLHttpRequest
• the ISO Scene Access Interface (SAI), an interface to control X3D scenes.

Combination of DOM, SAI and AJAX means

• using the SAI to access a real-time 3D scene;
• using the DOM to manipulate Web page content in response to changes in the 3D scene
• using server-request methods (XMLHttpRequest, createX3DFromURL) to store and retrieve data in response to, and/or leading to, changes in a 3D scene.

Current implementation status

• DOM and SAI are standards (and in principle implemented)
• AJAX simply means using the DOM XHMLHttpRequest. JavaScript is used to script interactivity on the client-side and to send request to a server.

The only challenge is to write libraries that will make this task easier. Therefore, the AJAX3D initiative aimes to Template:Quote (Parisi, 2006).

Clients

Any SAI-compliant X3D plug-in that supports JavaScript should be able to support AJAX3D,

Parisi et al. developed showcases on their website with their own FLUX player.

Server-side technology

• Bascially any, e.g. Apache/PHP/MySQL
