On Windows, it works only with Java 1.3 and QuickTime 4.
Both Java (jdk1.3.1_15 which bundles the 1.3 JRE) and QuickTime (QT4) versions can download
from the following URLs:
http://sonic.u-aizu.ac.jp/spatial-media/mixedreality/Java/java.zip

Multiplicity
We have extended Just Look at Yourself! to allow multipresence in collaborative virtual environment.
It has more features, including spatial sound.
Multiplicity is audio windowing system for workstation.

How to execute
We have developed client/server architecture. Before launching client applications, run the server application.
Otherwise the clients will run stand-alone.
Note: these applications are of "academic quality," and have numerous bugs and inconsistencies.
Server
Compressed file contains all the files including executable batch file Server.bat.
For Windows, just double click the Server.bat file and then it will launch and wait for the client applications.
For Sparc and Mac, launch the server from a command line:
java CVEServer
VR4U2C
Important reminder for Windows platforms: Because QT was rewritten to use the Cocoa architecture,
VR4U2C on Windows PCs requires QT4 and jdk1.3.
For Windows, if there are several Java versions besides jdk1.3.1_15, use the jdk1.3.1_15 path to run VR4U2C.
For example, if you installed jdk1.3.1_15 in directory C:\ use the following path:
C:\jdk1.3.1_15\bin\java VR4U2C
VR4U2C on Mac requires jdk1.4.
For example, to run VR4U2C on Mac OS X with menus at the top of the screen (like native applications),
use the following command:
/System/Library/Frameworks/JavaVM.framework/Versions/1.4.2/Commands/java -Dapple.laf.UseScreenMenuBar VR4U2C [-server <server>]
VR4U2C application allows users to connect to local or remote host.
To connect other clients locally, please select localhost.
