| Abstract: | A visual simulation system based virtual reality was introduced and the system was implemented in trains operation control simulation system. The algorithm of data fit was_designed according to the analysis of numerical value, and the problem of the visual output in real-time was resolved by the algorithm. The system was reviewed from the communication between the visual simulation and the platform of simulation system, the establishment and predigestion of model environment, and the visual simulation software. Based on personal computer as hardware platform, this visual simulation system has been used in the Beifing metro simulation system based on CBTC technology. |
