How to check if line segments intersect

Web9 jan. 2015 · Testing for intersection between segments is a bit more tricky than finding intersections between infinite lines on the form y = ax + b, as they are a bit easier to solve symbolically. When testing for intersection between two line segments, there are five … WebWhen the two segments intersect, the points (X1 (t1), Y1 (t1)) and (X2 (t2), Y2 (t2)) are the same. Setting the equations for the points equal gives: x11 + dx1 * t1 = x21 + dx2 * t2 y11 + dy1 * t1 = y21 + dy2 * t2 You can rearrange those equations to get: x11 - x21 + dx1 * t1 = …
