几乎所有的受访者基本上建议划分了一套

离散点集成一个三角形，然后计算交集

同级别飞机的轮廓代表这些矩形。这种方式

我们可以一次处理的“履带式”算法，而不是所有类型的水平

这是我原来一直在努力去工作。-Basically almost all of the respondents suggested dividing up the set of

discrete points into a set of triangles and then computing the intersection

of these rectangles with planes representing the contour levels. This way

we can process all the levels at once instead of the "crawler" type algorithms

which is what I had originally been trying to get to work.
