% Theory of operation: % % Given two line segments, L1 and L2, % % L1 endpoints: (x1(1),y1(1)) and (x1(2),y1(2)) % L2 endpoints: (x2(1),y2(1)) and (x2(2),y2(2)) % % we can write four equations with four unknowns and then solve them. The ...
python linex.pyThe test app's UI is very simple. Two line segments are drawn, and their intersection (if any) has a small circle drawn around it. One of the four line segment endpoints is considered the "active" endpoint, indicated by a small red circle. To change which endpoint is ...

TheSegSegmodule provides a functionintersectionthat calculates the intersection between two line segments and returns a tuple with three elements: Booleantrueif the two segments intersect at all,falseif they are disjoint An atom representing the classification of the intersection: ...
This chapter presents an algorithm to determine whether two line segments in 2-D space intersect or not and to determine the point of intersection. Rapid calculation of line segment intersections is important because this function is often called a primitive many number of times in the inner loops...
goal we must not allow more than two line segments to intersect in a point. The intersection points on the top row and the bottom are not included in our count; we can allow more than two line segments to intersect on those two rows. Given the value of a and b, your task is to ...
[xi,yi,ii] = polyxpoly(___)returns a two-column array of line segment indices corresponding to the intersection points. Thek-th row ofiiindicates which polyline segments give rise to the intersection pointxi(k),yi(k). To remember how these indices work, just think of segments and vertice...
