We use an adapted version of Nierstrasz's explore perl script as a Web spider to construct a raw list of Weblet links. The adaptations include the use of the libwww-perl libraries. The C++ program that creates a graphical representation of the Weblet links with the OOGL transformation libraries , which support 3D hyperbolic transformations. The original Euclidean version demonstrated in 1994 was called webspace. Due to the release of the popular VRML browser by that name from SGI, we have renamed the hyperbolic version webviz.
For a 3D Web browser we use the Geomview/ WebOOGL software system. Geomview is a public domain 3D viewer which runs on SGI, X, and NeXTStep workstations. The original WebOOGL system demoed in 1994  had a very different structure than the current WebOOGL 2.0 configuration. See  for details on the WebOOGL system.
