On using VRML format you can easily rotate
crystal structures on your desktop by your computer mouse.
In order to see the structures and to rotate them you need a special plug-in
(computer program) for your browser, called Cosmo-Player.
The official website is no longer available but you will find the Cosmo-Player by standard search machines.
You may download the Windows95/Windows NT version, even if you are running a higher version like (Microsoft Windows 98, Windows 2000, Windows ME or Windows XP).
- Open Microsoft Windows Explorer (file managing module) and click twice on the file:
cosmo_win95nt_du.exe, you have just downloaded. Follow the instructions of the
set-up-wizard (installation program). If you are browsing with Microsoft Internet Explorer,
the installation route will proceed by default.
- Netscape-Users: If you like to use Netscape, please proceed the following:
install the program like described above.
Click on a 3D-example and a Netscape plug in-window will be opened:
Now register in this window the Microsoft Internet Explorer (File: iexplore.exe).
You need to do this only once.
Click on a 3D-example and Netscape is opening the plug-in program with the Internet
There are other VRML-viewer, with lower quality. You will find them here:
Blaxxun Contact 4.0-Viewer can be downloaded here.
The installation is very simple. The 3D files are written in VRML 1.0 and the viewer opens them automatically on clicking.
Cortona-Viewer can be downloaded here. Note: The resolution is not the best one.
