Based on the requirements of the TV-track System-real time , swiftness , directness and trueness to life,a combination of Open GL with hardware is adopted as a solution to developing the TV - track system of a simulator. This paper introduces the whole construction of developing the visual simulation software of the TV - track system with the aid of Open GL , several key technologies conceming modelling , viewing , pattern version processing and target data driving , and then furnishes the results of simulation.
