| 摘 要： | 以石油地质勘探数据处理为应用背景，提出了一种含断层的不规则散乱数据域中等值线的绘制方法。对于数据域中的断层作为区域中的内边界处理，通过平面外推法对边界上的点进行插值。然后按照Delaunay三角剖分准则和边界约束条件通过生长法对区域进行三角剖分，最后进行等值线追踪和平滑，取得了较好的效果。

| Abstract: | Contour map is widely used in visualization of petroleum exploration data processing system.A contour map drawing method for irregular scatter data field is described with faults.Faults are regard as inner boundary of field and compute value on boundary by extrapolate,then triangular field is constrainted according to the Delaunay Max-Min Angle Criterion and boundary.This method acquire good contour map for irregular scatter data field with faults. |
