Abstract

This paper presents a 3D distributed virtual environment (DVE). The DVE, created using Java, is intended to allow for the creation of applications to enable multiple users to collaboratively interact in, and communicate about, a virtual world. This DVE is used to primarily support a flight simulator application. Three client-server synchronization methods were developed and compared. The method of transparent synchronization with non-blocking I/O has been found to be the best method for maintaining synchronization among DVEs. The successful creation of the DVE and the positive results collected in the supporting experimental data, leads to the conclusion that Java, with the addition of the non-blocking I/O and 3D API's, can be successfully used to create high performance 3D DVEs.
