WebFeb 25, 2012 · currently I write a program where finding out whether 2 line segments intersect is an essential part of the algorithm. Could anyone tell me if there's a way to determine if two segments are intersecting (i.e. whether the intersection point of 2 lines lies on each line between the points of each segment) without computing the exact … WebThe intersection of line segments algorithm is used to determine whether two line segments intersect with each other or not. The algorithm works by checking the orientation of the two line segments with respect to each other. If the orientation is different for both line segments, then they intersect. Otherwise, they do not intersect.
