摘要
用三维立体图的方式可以更形象直观地显示地物化资料,为了实现大网格资料的三维显示,本文介绍了一种简单、便捷通过顶点预生成与动态分块、分层LOD策略的方式,可有效解决地物化网格千万级大数据量的实时显示,同时利用分块、分层策略,通过局部更新的方式,实现了对网格数据平滑、拉升、降低等实时编辑修改,有效增强了系统的实用性。
Using three-dimensional image of the way to display the geophysical and chemical data can be more visual.In order to display a large three-dimensional grid data, the paper describes a simple, convenient way, which by Vertex pre- generated and dynamic hierarchical block. It effectively solved the display of tens of millions of geological grid data in real- time. While taking advantage of the block, layered strategy, by way of partial update, the paper discussed the grid editing by smoothing, pulled up, reducing in real-time, which effectively enhance the usefulness of the system.
