Through the analysis of relation of neighborhood bore-hole data,horizon interfaces with various complex boundaries were reconstructed by boundary representation(B-Rep) method considering the smoothness of the surface and the feasibility of modification.
考虑地层分界面的光滑性和整体控制性,运用边界表示法(B-Rep)和B样条曲面重构地层分界面,为地层建模提供了一种新的方法。
6) Polygonal method
多边形法
补充资料:凹多边形

把一个各边不自交的多边形任意一边向两方无限延长成为一直线,如果多边形的其他各边不在此直线的同旁,那么这个多边形就叫做凹多边形。
凹多边形的内角和的解,其实我们可以通过(n-2)·180来计算。实际上是把大于平角的角划分为两个角(如图)
