http://csharphelper.com/howtos/howto_segment_intersection.html WebFeb 16, 2024 · All other points on the line will have either t < 0 or t > 1. Similarly, points on the line segment connecting C and D have form s C + ( 1 − s) D for 0 ≤ s ≤ 1. The intersection of the two lines must have both forms, giving the equation. t A + ( 1 − t) B = s C + ( 1 − s) D. This is actually three equations in the two unknowns t and s:

To find out whether two lines defined by points ( p 1, p 2) and ( p 3, p 4) intersect within the part of the line truncated by the points, first of all check whether any of the points are identical. If not, then compute δ = p 2 − p 1 and γ = p 4 − p 3, then compute the determinant. d = δ x γ x δ y γ y . WebJul 15, 2024 · In other words - we should check all possible lines (combination of any 2 points) in polygon for a possible intersection. Check whenever any combination of 2 lines segments (from step1) can intersect. Obviously - not the most efficient method - complexity of this is about O (nˆ2). While our polygon not very big and complex, we can use it.
