To apply cache technology fold the data files which were going to be operated in CPU to the buffer memory directly, which could improve the resources utilization rate of the CPU effectively and the visualizing of the large scene watershed model in real-time interactive manner. Based on this goal, firstly discussed the differences between all kinds of memory as well as the current questions of the visualizing the large scene watershed model in real-timeinteractive manner , and then analyzed the methods to achieve cache technology, and presented the main algorithm steps to fold the data files. The results show that: the cache technique can not only take full advantage of the CPU resources effectively, but also improve the visualizing of the large scene watershed model in real-time interactive manner, which can make the visualizing of the large scene watrshed model more smooth and more coherent. ......
