To view vrml files, you may need to download and install a browser plugin.
Internet Explorer has the vrml viewer incorporated.

Geodesic spheres as vrml wireframes
These work on Internet Explorers and Cortona vrml viewer, and should work on blaxxun Contact 4.4 and COSMO.
If you need to install the plug-in, try Cortona -
You may need the VRML Converter also: Cortona VRML 1.0 Converter - a plug-in for Cortona VRML Client 3.1 that enables VRML 1.0 to be converted to VRML 2.0. This allows the user to view VRML 1.0 scenes with Cortona VRML Client 3.1
In the Cortona viewer, change the background to anything but black. The geodesic wireframes are black so the background should be a light color.
