Description
We describe how a new programming paradigm dubbed AJAX (Asynchronous Javascript and
XML) has enabled us to develop highly-performant web-based graphics applications.
Specific examples are shown of our web clients for: CMS Event Display (real-time
Cosmic Challenge), remote detecotr monitoring with ROOT displays, and performat 3D
displays of GEANT4 descriptions of LHC detectors. The Web-client performance can be
comparable to a local application. Moreover the web client does not suffer from any
of problems of software packaging, distribution and installation and configuration
for multiple platforms. AJAX, which uses a mixture of Javascript, XML and DHTML, is
spreading rapidly, helped by its support from industry leaders such as Google, Yahoo
and Amazon. We describe how AJAX improves on the traditional post/reload web-page
mechanisms, by supporting individual updates of sub-components of web pages and
explain how we exploited these design patterns to develop real web-based High Energy
Physics applications.
