I have a set of points and I have learned to use scipy.spatial.ConvexHull to get the boundary of the points. And I tried to use the attributes hull.equations to find out the lines which form the convex hull. current convex hull

The next step for me is that I need to find out a way to get the points with a given distance to the current convex hull. Or a direct way to know the new convex hull of these points. For example, let's say the incremental distance to the current convex hull is d, I need to find out the new points, or find out the new convex hull directly. Thus, I could know the incremental area as a function of the distance d. I have read the user guide of scipy.spatial.ConvexHull, but I am sorry I am not experienced in programming and can not think about a solution. Please give me guides. Any help would be much appreciated!

  • Does this answer your question? https://stackoverflow.com/questions/23937076/distance-to-convexhull – Serge de Gosson de Varennes Jan 21 '22 at 05:54
  • Thanks for the reply! That is useful and I have already used that for computing the distance. But what I need is the new convex hull or only the points at the given distance. It seems to be somehow a different problem. – FreeAir Jan 21 '22 at 14:56
