You need to get new friends, Pierce.

你得点新朋友了 皮尔斯。

16.your position distance 400 metres from intersection of reference line.

你的位置距参照点400米。

Because there are two points where the moon’s orbit crosses the sun’s plane, called nodes.

因为月球轨道与太阳平面的点有两点，称为点。

No other choice of two intersection points is guaranteed to get all the robo-ants within five minutes.

没有其他选择的两个点可以保证在五分钟内得到所有的机器。

17.your position distance 500 metres from intersection of reference line A and reference line B and distance 700 metres to port side of reference line C.

你的位置是参照AB点处500米，在距参照C左侧700米。

Now that we have a set of intersection  points on separate planes, we find whether the point is inside each corresponding triangle.

现在我们有了一组位于不同平面上的点，我们会找到该点是否位于每个相应的三角形内。

So let's see how these problems are solved and  we'll start by transitioning to a new scene and see how ray-triangle intersections are calculated.

那么让我们看看如何解决这些问题，我们将首先转换到一个新的场景，看看如何计算射三角形点。

So far we have established the preliminary conclusion that the volume of employment is determined by the point of intersection of the aggregate supply function with the aggregate demand function.

至此，我们初步建立了就业量由总供给函数与总需求函数的点决定的结论。

If there are no objects between  the intersection point and a light source, then that means that this point on the blue stripe  is directly illuminated by that light source.

如果点光源之间没有物体，则意味着蓝色条纹上的该点被该光源直接照亮。

This light is called indirect illumination, and in order to calculate it, we take the  intersection point from the primary ray and generate a secondary ray that bounces off it.

这种光被称为间接照明，为了计算它， 我们取主射的点并生成从该点反射的次级射。

The old man's route being along one side of an equilateral triangle, while Jim's was along two sides of the same, the former was at the point of intersection long before Hayward.

老人的路是沿着等边三角形的一侧，而吉姆的路是沿着等边三角形的两侧，前者在海沃德之前很久就在点处。
