The 3D Scene Search Engine (3DSSE) by the Multimedia Research Group of Athena Research Center uses X3DOM for visualizing captured Scenes.

Dive into it by searching the database – an empty query will show all available content – and navigate through the scenes here. (You can, for example, use X3DOM’s fly mode by pressing ‘f’)

Just another example of what people do with X3DOM:

Available through Mathworks’ MATLAB Central, the function FIGURE2XHTML exports your 3D Matlab figure to an X3DOM scene, which can directly be viewed inside your browser!
