To detect the number of intersections to the right from a point that is not aligned with a vertex, start with the formula of the coordinate where the horizontal line intersects a segment (Xi).

要检测未与一个顶点对其的一个点右侧的交点数量，首先使用水平线与一个线段(Xi)相交的坐标公式。

It says if I want to get the length of a segment, going to pass in that instance, it says from that instance, get the start point, that's the thing I just found.

它的意思是如果我想要，得到一个线段的长度，首先要把这个实例传进来，然后对于这个实例，从开始点，取得x坐标，然后通过同样的操作。

If it was, then it became the endpoint for the final segment. Otherwise, the code moved on to the next point.

如果是，它将成为最后一个线段的终点。
