三维地质建模及可视化研究

Study of 3D geology modeling and visualization

地质三维可视化是正确认识地质构造的重要手段,能为矿藏及各种地质现象描述提供科学的依据.本文研究了三维地质的建模方法,提出了一种快速构建地层的三角网格算法,给出了相应的数据结构定义,并在VC++6.0下实现了该算法.借助于OpenGL库及提出的算法,实现了地层剖切显示及地层缝合成地质体,达到了地质三维可视化的目的,并成功地将算法应用于实际的工程项目,取得了很好的效果.

3D visualization of geology is an important means to learn the geobody structure with useful and scientific proof for descriptions of mines and all kinds of geological phenomena. Modeling methods of 3D geology is studies because of the importance of 3D geology visualization. Algorithm of fast constructing stratum triangulation network and definition of data structure is presented. When algorithm in VC++6.0is accomplished the displaying of geology layers are carved,seaming adjacent layers into geobody. Through OpenGL library and algorithm, the goal of the geology 3D visualization is obtained. The algorithm is applied successfully to projectitem with a satisfying effect.
