建立具有多分辨率、海量数据的大规模虚拟地形场景越来越受到人们的关注,海量纹理数据的管理与生成算法是三维地景仿真的关键技术之一。本文在金字塔塔模型的基础上,运用面向对象思想,设计了多分辨率纹理数据的生成方案,对其流程进行了具体实现,对一些相关技术进行了讨论。通过试验表明,采用本文提出的方法,可以灵活地对全球影像数据进行管理和使用,对全球三维可视化具有一定作用。

How to implant a global virtual terrain environment with multi-resolution has caught attention of many scholars,the management algorithm for massive texture data is always one of the key techniques for three-dimension terrain simulation.In the base of pyramid model,this paper designed a new method for the genegration of multi-resolution texture with OOP.Some related problems are also discussed in this paper.The experiments show that we can do management and usage to global texture data easily if the methods...
