【摘要】 本文实现了一种基于局部多边形的复杂地质构造等值线图的填充算法.算法基本思想是:先对矩形网格的顶点值采用两段法估计,然后把断层线作为约束条件,将矩形网格划分为若干个的三角形网格,最后在三角形网格内完成等值线的追踪和填充.研究实例表明,该算法在油藏描述可视化中有很好的显示与应用效果.更多还原

【Abstract】 In this paper,an algorithm is introduced for contour filling about irregular and complicated fields.Following is the main idea of this algorithm.Firstly,the point value of mesh is estimated by the two-stage method;. Secondly,the fault lines are considered constraint lines,with the mesh divided into some triangles under the constraint lines.Thirdly,trace and fill contour on each triangle are obtained above.Experiment results show that this algorithm has excellent effects of displaying and applying in reservoir description.更多还原
