用地震解释结果重构地质界面或地质体是地震解释成果三维可视化工作中一个最关键的环节。本文提出了适合于地震解释结果数据特点的最近邻优先法三角片曲面几何重构算法并以实例说明了其实际应用效果。

Using seismic interpretation results to reconstrct geological interfaces and bodies is a key procedure in 3-D visualization of these results. This paper introduces the “nearest-point-first connecting”algorithm to rebuild geological interfaces or bodies mesh-geometry style which is suitable to the inter-pretation result data characteristic. Several examples are presented to say its actual application effect.
