Design and implementation for distributed collaborative virtual laboratory
Xinhua Zhu · Jisuanji gongcheng yu sheji · 2007
Distributed collaborative virtual laboratory techniques for network research and learning are discussed,and an implementation scheme using HLA(high level architecture) and Java 3D for the technology is proposed.This laboratory system is defined as a federation,the laboratory goals are achieved by federates which collaborate with each other.The federate consisted of four threads,among them Applet thread and remote updating thread are responsible for rendering virtual laboratory,federate main thread and RTI callback thread are responsible for collaboration control.All threads of federate are implemented.The collaboration of the threads is realized by using queues and blocked instances,and reentrant RTI problem is solved.The experimental result demonstrates that the scheme is available.
