The project makes extensive use of "LiveConnect" that is used as an interface between the VRML External Authoring Interface (EAI) from CosmoPlayer (VRML Viewing plugin) and Javascript with HTML. Therefore the code is unfortunately not portable to Internet Explorer or other VRML-plugins. In addition to that some of the Javascript functions (e.g. the eventCapturing of the mouse-movements) only work with Netscape 4.05 or above. Therefore viewing of these pages is limited to the combination "Netscape 4.05 or higher" and "Cosmo Player 2.1 or higher". We apologize for that.
