algorithm - Joining unordered line segments - Stack Overflow
My algorithm produces a list of (usually) several thousand line segments (all 2D) which I need to join up into large polylines. These resulting polylines might be closed or open, but they are never self-intersecting. 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.
Shortest distance between two line segments - Stack Overflow
I need a function to find the shortest distance between two line segments. A line segment is defined by two endpoints. So for example one of my line segments (AB) would be defined by the two points A (x1,y1) and B (x2,y2) and the other (CD) would be defined by the two points C (x1,y1) and D (x2,y2).
How do you detect where two line segments intersect? [closed]
Now move line segment b the same way and check if the new points of line segment b are on different sides of line a. If this is the case, check it the other way around. If this is also the case, the line segments intersect. If not, they don't intersect. Question A: Where do two line segments intersect? You know that two line segments a and b ...
Join multiple line segments into one line - GIS - Stack Overflow
Now, click on the last vertex of a line, and get the mouse closer to the vertex that you wish to join (QGIS will mark it in pink). After you have joined the line, remember to use the dissolve tool to merge attributes, so that only one row on the attribute table remains.
plot - Drawing line segments in R - Stack Overflow
I've got some x and y coordinates that I am trying to plot into line segments. And I'm getting some unexpected behavior from what I think should work. For each segment, there is a starting set of coordinates (x1,y1) and an ending set of coordinates (x2,y2). It's a data frame (call it 'df') that looks like this:
math - Merge 2d line segments - Stack Overflow
A line segment is made of up two vector points, the start of the line segment and the end point of the line segment. I want to join line segments that look like they should form the same straight line, I don't want to join the line segments if they are of completely different orientations but happen to have 2 points close to each other.
java - Overlapping line segments - Stack Overflow
// If line segments would overlap, this gets set to false. // boolean drawSegment = true; Line2D.Double segment = new Line2D.Double( sx, midy, tx, midy ); // Associate the middle-y point with the bounds of the target object. // On subsequent draws of targets with a similar mid-y, make sure that // there are no overlapping lines.
Finding The Shortest Distance Between Two 3D Line Segments
I have two Line Segments, represented by a 3D point at their beginning/end points. Line: class Line { public string Name { get; set; } public Point3D Start { get; set; } = new Point3D(); public Point3D End { get; set; } = new Point3D(); } The 3D points are just 3 doubles for coordinates X,Y and Z. 3DPoint:
python - Numpy and line intersections - Stack Overflow
I would like to add something small here. The original question is about line segments. I arrived here, because I was looking for line segment intersection, which in my case meant that I need to filter those cases, where no intersection of the line segments exists. Here is some code which does that:
c# - Algorithm for intersection of 2 lines? - Stack Overflow
The line case is a lot easier because any two non-parallel lines in an x,y plane will intersect somewhere, not so with segments – user316117 Commented Dec 28, 2015 at 18:31
