First, we check that segments lie on the same line, not on different parallel lines: ls != 0. Intersection of two segments on 1D line is the segment between their maximum left endpoint and minimum right endpoint. operator < we defined introduces strict ordering on any 2D line, so we can apply the solution from 1D case to find the intersection. Distance between two 3D lines ... Distance between the lines: Connecting line intersections: Angle between the lines: Connecting line vector:

Jan 09, 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 cases to consider. The code will go through these cases one by one. You can draw a line of minimum distance between and perpendicular to two lines in 3space. I know how to get the distance and direction of this line, but I want to locate the line in 3space so that I can find its midpoint.
