一种支持实时地景仿真的数据调度策略

复杂场景的实时绘制是当今图形学的研究热点。针对大型场景的实时绘制，本文提出了一种基于Ｃｌｉｅｎｔ／Ｓｅｒｖｅｒ结构的分布并行绘制模型，详细介绍了与模型对应的基于视点的场景数据动态分块策略和动态调度策略，并利用场景数据空间位置的相关性将１＋８＋１６的动态调度策略简化为１＋３＋５策略和１＋５＋９策略。在多武器平台综合防空体系的开发中，应用本文提出的绘制模和数据调度策略，并结合基于视点的ＬＯＤ模型的生成

A Kind of Data Schedule Strategy Supporting Real-time Scene Simulation

Real time rendering of extremely complex scene is one of the hotspots in computer graphics nowadays. Aiming at this problem,a distributed parallel rendering model based on Client/Server structure is presented in this article. The corresponding view dependent dynamic data partition and schedule strategy associated with this model is discussed in detail. By using position coherence of data blocks,the dynamic data schedule strategy named 1 8 16 is simplified into 1 3 5 strategy and 1 5 9 strategy. Using our model and strategy,the real time walkthrough of the scene is achieved successfully in the multi weapons aerial defense system,together with the view dependent LOD generation method. And the image quality is also satisfying,which illustrates that our method is effective. In addition,it is out of question to popularize our dynamic data schedule strategy to achieve the fast data exchange between hard disk and memory in local computer.
