The 3-D model and the gate test use VRML, version 2.0.
VRML
is the Virtual Reality Modeling Language, a
standard file format to display 3D models on the
web. The current version of VRML is referred to as
VRML 2.0 or VRML97.
The most common way to display, show, navigate,
browse, play, or view VRML files, models, or
worlds (.wrl file extension) is with a VRML
plugin, also known as a VRML viewer, player,
browser, reader, add-on, client, toolkit, program,
software, or ActiveX control. You must download
and install the VRML plugin in Internet Explorer,
Firefox, Google Chrome, or other browser.
