O3D is an open source (BSD license) JavaScript API created by Google for creating interactive 3D graphics applications that run in a web browser window or in a XUL desktop application. O3D may be crafted for use in any application area, however it is geared towards games, advertisements, 3D model viewers, product demos, simulations, engineering applications, control and monitoring systems, or massive online virtual worlds. O3D is currently in Google`s incubation lab, and originally built as a web browser plugin, the new implementation of O3D is a JavaScript library implemented on top of WebGL.
