Calculating the shortest distance between two lines (line segments) in 3D
How about extending the line segments into infinite lines and find the shortest distance between the two lines. Then find the points on each line that are the end points of the shortest distance line segment.
How to efficiently check if two line segments intersect?
Checking whether two line segments have a shared coordinate is a trivial check that you do first, before running the standard line/line intersection math. As for "Line segments shouldn't be considered intersecting just because they share the same slope": slope is undefined for vertical lines, so don't work with, or think it terms of, slopes.
How do you detect where two line segments intersect? [closed]
Otherwise, the two line segments are not parallel but do not intersect. Credit: this method is the 2-dimensional specialization of the 3D line intersection algorithm from the article "Intersection of two lines in three-space" by Ronald Goldman, published in Graphics Gems, page 304.
How can I check if two segments intersect? - Stack Overflow
8 Based on Liran's and Grumdrig's excellent answers here is a complete Python code to verify if closed segments do intersect. Works for collinear segments, segments parallel to axis Y, degenerate segments (devil is in details). Assumes integer coordinates. Floating point coordinates require a modification to points equality test.
algorithm - Joining unordered line segments - Stack Overflow
The line segments are not directed, i.e. it might be needed to flip a line segment before it can be joined to its neighbour. What would be an extremely fast way of finding these polylines? I have to do this in real-time, so anything that takes longer than -say- 10ms is not a solution. I'm doing this in C#, but I'm looking for ideas, not source.

Plotting numerous disconnected line segments with different colors
In general, any two line segments are disconnected (meaning that their end-points do not necessarily coincide). How to plot this data using matplotlib with a single plot call (or as few as possible) as there could be potentially thousands of records. Attempts Preparing the data in one big list and calling plot against it is way too slow.
Finding a distance between two line segments? - Stack Overflow
5 Given two line segments, find the two points at which the distance between the line segments is d. This is similar to the "shortest distance between two line segments problem", except we are solving for the two points on the line segment separated by a given distance d. Each line segment consists of two 3-dimensional points.
Line Segments in Matplotlib - Stack Overflow
6 Given coordinates of [1,5,7,3,5,10,3,6,8] for matplotlib.pyplot, how do I highlight or colour different segments of the line. For instance, the coordinates 1-3 ([1,5,7,3]) in the list represent attribute a. How do I colour this bit of the line and mark it in the legend? Edit: The list in question contains tens of thousands of elements.
Intersection of two line segments in Python - Stack Overflow
Different articles have discussed about the intersection of two line segments in Python such as How do I compute the intersection point of two lines?, Numpy and line intersections, How can I check ...
