ON AUTOMATICALLY DRAWING GEOLOGY GRAPHICS USING VISUALIZATION TECHNIQUE

研究利用可视化技术自动生成地质图件。首先给出限制条件下的区域Delaunay剖分原理;其次采用了地质统计学中的克里金插值技术建立图件模型,提出了"多边形"扩张法搜索待插值三角网格顶点邻域内的已知采样点,以"距离环绕法"处理了断层和边界对插值结果造成的影响;结合地质图件自动建立过程;最后给出了一个具体的应用实例。

In this paper we studied the way of automatically drawing geological graphics using visualiZation technique. Firstly, we gave out the principle of regional Delaunay triangulation with restricted conditions. Then we used Kriging interpolation technique in geological statistics to establish geological graphics model, and presented the method of searching known sample points in the region to be interpolated adjacent to triangle mesh vertex with＂ polygon＂ expanding,and the method of dealing with the impact of boundary and faultage on interpolated results by distance revolving. In the end, combining with the process of automatically drawing geological graphics, we provided a concrete practical example.
