DeepMatrix 3D multi-user system
Introduction
“DeepMatrix is an open-source Java server/client 3D multi-user system capable of both chat and shared events working in conjunction with VRML/X3D browsers. Users appear as avatars in a shared 3D scene. [...] The latest version of DeepMatrix is composed of a Java server and Java standalone-client application. It uses the latest Sun Java Runtime Environment and is designed to work with standalone VRML/X3D viewers that have Java EAI or External SAI capability.” (deepmatrix.org)
Presently, DeepMatrix works with the free Instant Player client.
DeepMatrix was originally developed by a team led by Gerhard Reitmayr from the now-defunct Geometrek.com site in the late nineties. This project in turn was based on the VNet EAI applet by Steven White and Jeff Sonstein.
The new version seems to work better and has additional features. Active project when last checked in Sept. 2010 - Daniel K. Schneider
Short how to
Prerequisites

- (2) Install the very latest Instant Reality X3D/VRML player
- Windows (msi installer): Take it from the FTP archive.
- Other systems: Find your version in the FTP archive. Be careful to select the player and very right version, e.g. File InstantReality-Ubuntu-10.04-x86-2.0.0.20206.deb File for a typical 32-bit 10.04 LTS - the Lucid Lynx - install of April 2010.
