分布式环境下的并行处理ARC/INFO飞行动画生成技术

Generation of Flight Animation of ARC/INFO on Distributed Environment

针对ＡＲＣ／ＩＮＦＯ系统中飞行动画生成速度慢的问题，分析了速度慢的原因，提出了用并行处理技术来加速的思想，设计了相应的并行算法，并在ｃｌｕｓｅｒ结构上实现了飞行动画生成并行处理．经实际应用达到了提高计算速度、满足实时性要求的目的．

ARC/INFO system is widely used in GIS. But the system does not satisfy the user's real time requirement when it is used in large scaled computing. This paper analyses the reason why the speed of generating a flight animation is very low. A strategy of using parallel computing for acceleration is proposed according to the analysis and the arithmetic is designed. The system can generate flight animation parallel on Cluster architcture. It meets the user's requirement for real time handling.
