on the other hand, the ray methods have faster speed, but sometimes they introduce singularities at ray-crossing points.

the method combines vector and ray-crossing. and the method solves the abnormity which ray-crossing takes on.

该方法将矢量和射线法结合，彻底解决了射线法所具有的奇异情况。

as can be seen from the illustration, the sum of the values from a given ray crossing the segments in its path is zero.

从图中可看出，给定射线与其路径中的段的交叉值总和是零。
