How can I check if two segments intersect?  Stack Overflow
If you need the intersection point, then the answer by OMG_peanuts is a faster approach. However, if you just want to find whether the lines intersect or not, you can do so by using the line equation (ax + by + c = 0). The approach is as follows: Let's start with two line segments: segment 1 and segment 2.
How do you detect where two line segments intersect? [closed]
Suppose the two line segments run from p to p + r and from q to q + s. Then any point on the first line is representable as p + t r (for a scalar parameter t) and any point on the second line as q + u s (for a scalar parameter u). The two lines intersect if we can find t and u such that: p + t r = q + u s. Cross both sides with s, getting.
Line Segments in Matplotlib  Stack Overflow
Yes, you need to redraw the line, but you can clip the line so that only the part you are interested in is visible. To do this I create a rectangle covering the area that represents prop (a), then I use this to create a clip_path. import matplotlib.pyplot as plt. from matplotlib.transforms import Bbox. data = [1,5,7,3,5,10,3,6,8] X0 = 1. X1 = 3.
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).
c#  The algorithm to find the point of intersection of two 3D line ...
There are two approaches to finding the shortest line segment between lines "a" and "b". Approach one: The first is to write down the length of the line segment joining the two lines and then find the minimum. That is, minimise the following.  Pb  Pa ^2. Substituting the equations of the lines gives.
python  How to draw a line with matplotlib?  Stack Overflow
The line will span the full range of your plot (independently on how big it is), and the creation of the line doesn't rely on any data point within the axis, but only in two fixed points that you need to specify. import numpy as np. x = np.linspace(0,10) y = x**2. p1 = [1,20] p2 = [6,70] plt.plot(x, y)
Calculating the shortest distance between two lines (line segments) in 3D
I have two line segments: X1,Y1,Z1  X2,Y2,Z2 And X3,Y3,Z3  X4,Y4,Z4. I am trying to find the shortest distance between the two segments. I have been looking for a solution for hours, but all of them seem to work with lines rather than line segments. Any ideas how to go about this, or any sources of furmulae?
Calculation of intersections between line segments
The point of intersection is equivalent to a solution of a system of equations representing the two lines. Really, y = a1*x + b1 and y = a2*x + b2 intersecting basically means that both of these equations hold. Solve this system by equating the two right sides and it will give you the intersection point.
Overlapping line segments in 2D space  Stack Overflow
For two colinear line segments that are not necessarily axisaligned: Sort the vertices in clockwise order around the origin. The lines overlap if the ordered vertices alternate between the two segments, e.g. Line1.Point1, Line2.Point1, Line1.Point2, Line2.Point2.
How do I compute the intersection point of two lines?
@firelynx I think you are confusing the term line with line segment. The OP asks for a line intersection (on purpose or due to not understanding the difference). The OP asks for a line intersection (on purpose or due to not understanding the difference).
