Help with Three-Dimensional Objects

The use of three-dimensional objects on the Web remains, unfortunately, without adequate support or standardization. An older technology to allow for interactive three-dimensional content was the Virtual Reality Modeling Language (VRML), which has now been replaced largely by a new standard that grew out of it referred to as X3D. One of the biggest drawbacks to either is that support for their use does not come automatically in browsers, but rather has to be added in via special plugins. These plugins are free and easy to install, but unfortunately many users don't want to take the time to do. In addition, as VRML has become replaced by X3D, the older plugins have worked increasingly erratic with new versions of the various browsers, and you have to be concerned with the type of browser, version of browser, type of operating system, and version of operating system. Finally, the precise nature of controls and functions varies, so instructions are specific to which plugin you are using. See below for details on various plugins and browsers.

Our main three-dimensional project is an immersive reconstruction of Meru Nyingpa Monastery in Lhasa. This fully interactive virtual model of the complex allows visitors to explore the spaces of Meru Nyingpa. Links inside the monastery rooms and spaces provide detailed information and visual media of each space, while audio samples taken from the actual site provide a sense of the sounds of the community inhabiting these spaces.

If the frame on the left does not load the entrance to the monastery (give it some time if you have a slow connection - this is a whole monastery!), you probably need to install a viewer - see below for links. One you are at the entrance to the monastery, you may "walk" through the grounds, enter the main temple, even go upstairs and examine the rooms. Click on the blue wheels that appear in different rooms or areas to see pictures and video taken at Meru Nyingpa, as well as short textual descriptions of the corresponding room or area.

Firefox for Windows

Cortona worked great in previous versions of Firefox, but with Firefox 3.0 it caused any pages with VRMLs to crash the entire browser. Octaga 2. 3 and 2.2 both crash Firefox as well. At this point Firefox itself seems defective and we can only recommend not using Firefox 3.0 for viewing VRMLs.

Internet Explorer for Windows

In contrast to Firefox, IE works great with Cortona and Octaga's most recent versions.

Safari for Mac

We recommend FreeWRL for use on a Mac.

Plugins

external link: http://cic.nist.gov/vrml/vbdetect.html is a great survey of all the various plugins and players that can be used with VRMLs and X3D three-dimensional objects. We have not at present tested all of these plugins and players, and would be happy to hear of users' experiences with them.

Version: As of August 18, 2008, 2.3 was the version of the new beta player, and 2.2 ws still the only official release.

This is the the most current of the plugins, and is actively supporting newer X3d technologies, while maintaining backwards compatibility with VMRL models.
