   Jul 30, 2019 · Here is a github repo on finding the concave hull for a set of points using python. My recommendation to you is the following. Create a set of points using the endpoints of each line. Then use the linked to code to generate a concave hull for these points, with some guess for the value of alpha.

   A simple (but non-obvious) computational geometry algorithm for determining convexity is to check that every triplet of consecutive vertices is CCW. This takes just a few lines of Python geometry code (assuming that the points are provided in counterclockwise order—if points is in clockwise order, you’ll want all triplets to be clockwise):

   A concave hull is visualized using the red line in the image below (the blue line visualizes the convex hull). Intuitively, it is a polygon which embraces all the points, but has less (minimal?) area compared to the convex hull. As a result, the polygon's boundary length is longer.

   Why is concavity important?

   • Concavity provides valuable insights into how a function curves, distinguishing between concave upward and concave downward shapes, while points of inflection mark locations where the curvature changes sign.

   How many types of concavity exist in a function?

   • There are two types of concavity that exist in the function, Concave Up: A function is said to be concave up on an interval if the graph of that function lies above any tangent that is drawn on any point of the interval.

   How do you know if a function is concave?

   • To identify concavity, we analyze the sign of the second derivative of the function. If the second derivative is positive, the function is concave upward, and if it is negative, the function is concave downward. Points of inflection are found where the second derivative changes sign, indicating a change in concavity.

   How do you find the inflection point of a concavity function?

   • We can find the inflection point by equating the second-order derivative of the function and solving for the points, and then at these points we can check the concavity change. What is Concavity?

   What is a concave inflection point?

   • An inflection point is defined as a point on a curve where the curvature changes from concave up to concave down, or vice versa. This transition is identified by either the second derivative of the function being zero or non-existent at that point.
