A Research On The Theory And Technology Of Collaborative Virtual Battlefield Discussion Environment

Collaborative virtual battlefield discussion enviroment, as an practical application of battlefield enviroment simmulation techniques based on net, is the Collaborative discussion command platforme that commanders at diffent areas can paticepate in at the same time. The vitual battlefield enviroment based on this platform makes it possible that geographic distributed commanders are able to particpate in the same real enviroment,and carry out Collaborative training and command by real time graphic sound and script, and also can simulate the simulative scheme by kinds of ways such as case analysis, war simulation and damnification evaluation, constitute the elaborate campaign plan with systemic aided analysis.Collaborative virtual battlefield discussion enviroment characteristics mianly include:●Internet-based 3D visualization;●Data sharing on the network (via document or database storage sharing);●Various discussion modes (e.g. text chatting, electronic white board, video, audio discussion);●Aimed at discussion, video, audio as well as Collaborative apperceive ability of legitimate users in Collaborative virtual battlefield discussion enviroment;●Custom the space range of virtual battlefield enviroment used in Collaborative operation, and Collaboratively deliberate on the preestablished task, manoeuvre plan, campaign purpose in this approximatively real enviroment.Collaborative virtual battlefield discussion enviroment is the extent and development of traditional Collaborative virtual enviroment, integrates cyber-cooperation, virtaul reality, internet-based 3D visualization, media streaming, becomes a new method of military automated command system ensurer under high tech condition. This paper reseaches the theory and realization techniques of Collaborative virtual battlefield discussion enviroment deeply based on enough understand of Collaborative virtual enviroment theory, and explores a prototype sysytem.This paper's main work is as following:(1) After sufficient discussion of Collaborative virtual enviroment model system, bring forward the framework system of Collaborative virtual battlefield discussion enviroment, carry out elementary realization and practice;(2) Implement the network display of 3D virtual enviroment based on Java and JOGL, solve the mass data net transfers problem by dint of Java's net and paltform independency;(3) Achieve reasonable use of media streaming in distributed Collaborative virtual battlefield discussion enviroment, satify the requirements of real time deliberation in millitary training and manoeuvre, and realize Collaborative work under distributed cinditions;(4) Study and basically accomplish Collaborative military plotting, offer real time long distance Collaborative work mode of battlefield state plotting;(5) Explores the prototype sysytem;...
