摘要
根据细节层次模型(LOD)的设计思想,提出了大规模数字高程模型的数据组织和可视化方法。该方法在数据分页算法和细节层次模型相结合的基础上,采用视区计算和边界融合算法,实现了地形的快速绘制。实验证明该方法实现了高性能绘制大规模数字高程模型。
The article describes the data organization and visualization method of large scale digital elevation model based on LOD method. The methods implements the fast render of the terrain by using the view port calculation and the border combination based on the data-paging algorithm and the model of the level of details （LOD）. Results of experiments show that the method can archive the good performance for rendering of the large scale digital elevation model.
