WebJan 31, 2024 · An edge crosses an horizontal line when the ordinates of its endpoints (let a and b) straddle the ordinate of the line (let Y ). Hence an intersection test is very simple. To get the intersection point itself, use Xi = Xa + (Y - Ya) (Xb - Xa) / (Yb - Ya) Yi = Y What to do when Y = Ya = Yb is application dependent.
