The Key Techniques of a Distributed Virtual Reality Flight Training System
Guanzhong Dai · Jisuanji gongcheng · 2000
Virtual Reality has been already widely used in various simulating and training systems. This paper concentrate on a distributed virtual reality flight training system. The first key technique we researched is to construct an architecture of the DVRFTS. This architecture includes: high speed network, distributed obiect-relational database. platforms of simulation graphics. and some input/output devices. The second kev technique is our proposal of a distributed object-relational database which integrates the extented relational databases (NF2) and object-oriented databases techniques. The third key technique is our adaption of UDP of TCP/IP as network protocol. This protocol can obviously reduce the dalay of information transport The fourth key technique is our proposal of a synchronization model ITSPNs (Inhibit Time Stream Petri Nets) which takes into consideration the distributed VR environment.
