Metisse is a window manager developped by the In Situ project. It is available under the GPL Licence. Mandriva Linux is using Metrisse in its latatest Live-CD. Metisse differs from a ‘classic’ 3D desktop in the way that it offers innovative windows interactions, thus enforcing work efficiency. It is using basic openGL commands for most of its feature and can run on entry level 3D graphic cards. This workshop describes the hard disk installation and Mandriva One setup. Additionally you will find information how to use the Metrisse 3D Desktop.
