A Java-based Multi-participant 3d Graphics Application Interface Using Javagl and Javanl

This paper proposes a Java-based multi-participant 3D graphics application interface to provide 3D graphics and interactive capabilities over network. Two libraries support this interface, one is a 3D graphics library, called JavaGL, and the other is a network library, called JavaNL. The 3D graphics library is almost identical to OpenGL application interface but is written in Java to satisfy the 3D graphics requirement of the application model. The network library follows the concepts of Distributed Interactive Simulation (DIS), and is also written in Java. With these two libraries, we are able to provide an interactive application written in Java, gains the flexibility in cross-platform capability, while maintaining reasonable performance over Local Area Network (LAN).
