摘要
WorldWind是美国航天宇航局（NASA）研发的一款三维地理信息系统软件。由于WorldWind每次只能加载单个KMZ模型文件,加载效率过低,所以给基于WorldWind三维模型加载的科学研究来带来了很大的不便。基于worldwind对KMZ文件批量加载的需求,该文通过分析KMZ文件内部结构,改进了WorldWind中用于KMZ文件加载的相关代码,最终实现了KMZ文件在worldwind中的批量加载,为基于worldwind的后续研究提供了便利。
WorldWind is the U.S. space agency（NASA） produced a three-dimensional geographic information system software.WorldWind without their own 3 d model file format, just provide a. Point x file loading interface. Because of the limitation of format is required when the 3 d model implanted WorldWind through commercial plugin to convert the format first, then to load, so that to scientific research to a lot of inconvenience, 3 d model and easy to lose in the process of transformation of material, layer, and other important information. Based on load demand, this paper analyzes KMZ file internal structure, improve the load in the WorldWind class code, created the KML file loading port WorldWind programs. Finally, through further research,this paper realizes the KMZ model bulk loading WorldWind, and based on the three-dimensional model for subsequent ray tracing study to lay a solid foundation.
