Research Of Multi-frame-smooth Strategy Of Animation Display In Simulation Platform

As the rapid development of the computer technology, the research fields of computer are expanding towards an increasing number of aspects. Computer simulation, as the research hotspot now, has attracted more and more attention. The simulation show results formed by the combination of computer simulation data and computer amination technology can give a person realistic effects, in order to help people to understand the activity and behavior of simulation object better and faster.Simulation animation displays has been used at the Information-based modeling and simulation platform to determine the support ability of equipment load. However, there exists the phenomenon of pause in the process of animation shows. This paper has carried on analysis and research thoroughly in view of this phenomenon, and has proposed the predictive caching model of the client. This model is composed of display module of the client and the module of cache predictive, it divided cache into three parts:the display cache which store the data that will be played, the displayed cache which store the data that has been played and the predictive cache which store the data that is predict through the predictive module. Through the coordination between them, the purpose of improving cache hit rate were finally achieved.According to the principle of the model, and in terms of all the data latency of user's requests. This paper has introduced the caching mechanism and data prefetching mechanism, and on the basis of analyzing and researching the traditional caching and prefetching algorithms, this paper has proposed the prefetching cache replacement algorithm which is based on business relation and is very suitable for the simulation platform. This algorithm includes two parts:The first part is that it introduces the concept of virtual cache in cache replacement algorithm, so as to resolve the problem that the records of all the caching data has been visited is cleared because of being replaced in traditional algorithm; Another part is that based on an overall consideration of the popularity and the cost of bytes, this paper has presented the prefetching algorithms based on popularity bytes price. This text has combined prefetching and cache together, and has controlled the prefetching time and prefetching quantity properly through prefetching control and prefetching threshold, so as to resolve the conflict problem caused by the shared storage space of cache and prefetching reasonablely. Finally, this paper has applied the proposed multi-frame-smooth strategy on the simulation platform, and has given the simulation show results. Through comparison and analysis, the results have showed that the strategy can reduce the average response time of every frame of the animation loading and improve the effect of animation's multi-frame-smooth effectively.
